DRO PROS 2G Basic and Special Functions Explained:


Clear Zero - Sets the current position to zero. Allows the operator to specify any desired point as the "0" reference point.

Inch/Metric Display Conversion - Allows the operator to choose between inch and metric display. Resolution is .0002" or .005mm.

Direct Entry - Allows operator to manually input desired dimension / coordinate.

Result Transfer - A point value computed from the calculator feature can be entered and found.

ABS/INC (Absolute / Incremental) - Allows the operator to switch between absolute and incremental display. 'Absolute' display references the work piece zero coordinate you designate. You may choose the absolute center point of your workpiece or perhaps a corner of your workpiece, the decision is yours. Incremental display references any arbitrary coordinate/position without losing your designated zero point. For example, to locate a point exactly in the middle of your workpiece you would most likely use 'absolute' display to locate the point. To locate points exactly .78 distant from an arbitrary point somewhere in the middle of your workpiece, you would then switch to 'incremental' display, designate the present position as a zero point, and then simply move your workpiece until .78 was displayed. 

Center Find Function - Automatically calculates the center of the workpiece after the edges are located.

199 Reference or Sub Datum Memory (SDM) Points - Are you doing any sort of repetitive machining? Wouldn't it be great to be able to create exact copies of your original workpiece? Well now you can - either enter your points as you move to them on your workpiece or simply enter them in a list format - the choice is yours!

Power Off Memory (Ref Datum Memory) - This function allows the operator to store the work piece zero position in memory. If the machine is turned off at night or there is a power failure, the zero reference point can be recovered without having to reestablish the work piece zero point.   

Parameters Setup - Enables you to swap or 'reverse' the direction a scale reads, also allows the operator to perform a memory check.

Linear Error Compensation - This function allows the operator to compensate for linear error.

Non Linear Error Compensation - This function allows the operator to compensate for non-linear error. Normally only available in readouts costing twice as much, Non-Linear Error Compensation dials in scale accuracy to the micron!

Vibration Filtering - Filters the display to obtain a more comfortable reading.


High Noise Immunity & (EMC) Design

A triple stage noise filter is used in the 2G for transducer signals input noise filtering which offer very wide frequency bandwidth (1 KHz-1000MHz) noise attenuation. Extreme care was taken in PCB and component layout to achieve the highest possible noise immunity and EMC performance.


Adaptable to Poor Electrical Sources

A low power consumption approach was used in the system design of the 2G. The 2G can handle a wide range of supply voltages (160v~260v/80v~130v). The 2G's linear power supply offers excellent noise immunity and proven highest reliability without serious heat generation. Use of a combined capacitor-varistor noise filter in the power supply system ensures the highest possible noise and surge immunity to poor electrical sources.


High Durability Switch Membrane

An Autotex series polyester film from UK'S Autotype Ltd. is used as the key membrane of the 2G. Autotex polyester film is known as the highest quality, highest specification membrane film available in the membrane switch manufacturing industry. Autotex film offers excellent switch life and chemical resistance to the most commonly used industry solvents. Switch life expectancy is rated at a minimum of 100,000 cycles.


Robust Casing, Chromium Plated Panel

The front plate is made from 1.5mm thick electroplated steel. The high strength 3.5mm metal casing provides a high quality, robust housing.


Ultra Low Temperature Rise Transformer

Reducing heat generation is critical to longevity. An ultra low temperature rise high permeability iron core transformer is utilized, which significantly reduces core temperature rise to about 5 degrees Celsius.


State of the Art Electronics Technology

A custom 3 axes counting ASIC designed with CMOS technology greatly reduces the number of component counts, which lowers the system power consumption and yields greater reliability.


Advanced Production Technology

An SMT assembly process is used in manufacturing the 2G. All components are soldered by computerized control soldering machines to achieve the highest quality soldering possible.


Totally Sealed Enclosure

The enclosure of the 2G is completely sealed to protect the electronic circuitry against the hazards of a typical shop environment, such as dust, evaporated coolant, fumes, etc. To avoid overheating of the PCB caused by the totally sealed enclosure, a metal front plate and panel is utilized to quickly dissipate generated heat.


Non Linear Error Compensation

In an application where a very high degree of accuracy is required, such as grinding machines, boring machines, etc. it is very costly and also very difficult to achieve the required micron grade accuracy. The 2G offers a very cost effective way to improve the display accuracy by utilizing non-linear error compensation. The non-linear error compensation function of the 2G is very similar to the non-linear error compensation that is commonly found in CNC machine controllers.


Glass Scale Kits

At DRO PROS, we only sell true five bearing scales with our glass scale kits, and with over 70 different size scales to choose from, we fit your machine right! For .0002" resolution scales up to 39.3" in capacity (models 100mm - 1000mm), the scales are included in the price of the kit and there is no surcharge. Simply tell us what size scale you'd like and we'll send the correct length scale. For scales greater than 39" capacity (our oversize scales), there is a small surcharge based on length when purchased with a kit.

Why does DRO PROS post their digital readout part prices online when other companies don't?

That's because if you were to find out what other companies are going to charge you for parts

when you need them, you might not buy their digital readout kit in the first place!

At DRO PROS, we're proud to show off our low part prices. 




Why should you buy from DRO PROS?

We speak English - We answer our phones - Same day shipping

Veteran owned, Veteran managed - and proud of it!


Our goal is to make customers for life. We feel that, in the long run, treating customers right will yield much more than simply "going for the sale". In accordance with that, we have attempted to pass on some ideas to help you, the customer, in completing your purchase decision:


Price. Probably the most talked about factor when buying a digital readout. Price can also be the most misleading, and perhaps worst way, to judge a digital readout kit. We've all heard the old adage, "You get what you pay for." Before the internet, it was true, price did generally correlate directly to value. But that was yesterdays economy. All resellers obtained their goods the same way, and therefore incurred the same costs. In today's economy, the market has changed drastically. At DRO PROS, we import and sell directly to you. Unlike our competitors, we do not have Western and Eastern sales divisions and multi layers of management to support. One location, one cost, and the savings get passed on to you!


Intuitiveness or "Ease of Use". Probably the most important, and hardest to determine factor when buying a readout. Think in terms of after the sale. Even if you get an absolute 'rock star' bottom line price that would make William Shatner proud, if the digital readout is not user friendly, you still didn't get a 'deal'. The whole point of getting a digital readout is to make your work easier and more enjoyable. If the digital readout is poorly designed, too complicated, if the display isn't bright enough, or in other words is 'user unfriendly', you'll regret your purchase decision every time you turn it on. It simply won't matter what you paid, it's not worth it!


Support. Most likely the second most important, and perhaps most overlooked factor when buying a digital readout. Imagine trying to reach a technician when you've bought a digital readout from an overseas reseller! Yet every day, people "save" $50 and buy products on eBay without stopping to think what will happen when they need service or tech support. Some digital readout resellers don't even publish a phone number! While our competitors continue to pare down or even totally eliminate their customer support, we continue to expand our Customer Service. Our Video Tutorials are the best in the industry, and are available free for you, our customers. Our tech help is the best in the business - our techs all know our readouts inside and out. Nobody knows digital readouts like DRO PROS!


Warranty. DRO PROS is proud to offer the industries safest, longest, 6 year warranty on all of our Electronica magnetic scale kits. All of our DRO PROS brand glass scale kits come with a full 3 year warranty, and our EASSON kits come standard with a 1 year warranty. DRO PROS brand warranty claims are handled directly by DRO PROS. No run-arounds, no hassle! Something not working as expected? Call us, don't get redirected overseas like the other guys!


Parts. Can you believe some resellers don't carry parts? That's right, buy from the "other guys", break a scale, and you get to replace the entire digital readout kit! Don't assume you can just go buy a different brand scale, either, because most manufacturers use different connectors on their scales. If that wasn't enough, even among those with a common connector, such as a DB9, most are hard wired differently. Finally, don't overlook the cost of parts. At DRO PROS, an 800mm replacement scale will cost you $197. A similar scale sold extensively by a European company will cost nearly $700! Finally, we have a massive inventory of parts, so rest easy - a replacement part is only a phone call away!


The Best Value. We literally search world-wide for the best value digital readout products on the planet. If there was a better digital readout package to be sold, we would be selling it. Yes, we've seen cheaper units on eBay, but there is a reason they're cheaper. Think poor quality, no parts, no manual, non-existent customer service, poor product fit/finish etc.


Customer Service. We pledge to never "over sell" you on a product that won't work well for you. Our philosophy is to try and save you money and get the best value kit tailored to the machinery you have. Many of our customers are surprised when we recommend against buying a more expensive brand. Again, our philosophy is to build customers for life. Give us a call and let us save you money!


Shipping. Most orders ship the same day, the next at the latest. We do not 'drop' ship, we have our own massive warehouse of inventory right here on site. We use UPS, you'll get a tracking number emailed to you immediately, and we cover all shipping insurance automatically.


The Company. DRO PROS is a veteran owned, American company. We enjoy selling quality products at competitive prices. We believe that  providing the best customer service is the key to success. No other company spends more time on the phone with customers than we do. Even in a down economy, our company continues to thrive and grow. We look forward to earning your business! 


The Bottom Line. Our line of digital readout's are simply the most user friendly readouts on the planet. Because of our direct marketing structure, they're also extremely affordable. Coupled with our extensive customer service and affordable parts, our Digital Readout products are simply the best value on the planet.




Domestic Shipping to the United States: All digital readout shipping is done via UPS for a flat rate of $43. You'll get a tracking number emailed direct to you from UPS, enabling you to track your shipment door to door! We cover insurance against any potential shipping damages, so no hidden fees here!
