A Simple How-To Guide on a Metrology DRO

How to Master Displays, Set Tolerances, and Print to USB on a GAGE-CHEK

HEIDENHAIN’s metrology digital readouts (DROs) offer numerous functions for measured data acquisition and statistical evaluation of measured values.  HEIDENHAIN’s popular ND 2100G GAGE-CHEK is one of the Evaluation Electronics offered for metrological applications, and setting some basic programs couldn’t be easier.

Especially useful with multipoint inspection apparatuses and SPC inspection stations, the GAGE-CHEK can easily be set to master displays, set tolerances and print to a USB.  See examples below.

Master Displays

Start by clicking the Master softkey.

This will bring you to the Mastering screen, where you can calibrate your probes to a known standard, such as a gauge block, or zero out your display.

Screen1

 

 

Here you can enter the values you wish to set the current position at, and hit enter.

screen2

 

It will now prompt you if you want to Master now. Hit the YES softkey.

Screen3

 

It will now set your position values accordingly. Press finish to return to the main DRO screen.

Screen4

Tolerance setting

Start by pressing the Menu softkey. Then hit it again when it shows Setup.

Screen5

 

Scroll down to the Tolerances tab and press enter.

Here you can change your Warning, Limit and Max and Min levels of Tolerance for each channel. Simply scroll down and enter your values using the number pad.

You can see an apply all and mirror button as you enter new tolerances.

This is the result when the first tolerance was manually set and then the mirror button was hit.

Screen8

 

Here is what happens when you hit apply all.

When you hit YES, it will apply the same tolerances across all dimensions.

Screen9

 

You can also assign an audio alert to warn when the warning and/or limit tolerances are reached. You will also notice an Apply All button that will apply the same rule to each dimension, separate of the tolerances.

Press Finish and you will have set your new tolerances.

USB Printing

Scroll down to USB within the Setup menu.

Screen11

 

Then, set the Data field to Report.

Screen12

 

Set the Destination to File.

Screen13

 

And then you can choose how you want the file to save—if you want it to replace the old file, append the old file, or make a new file with numbering.

Screen14

 

The last setting you need to check is the RS232 settings just above the USB settings. This needs to be set to None.

Screen15

 

Finally, now that all the settings are correct, you can simply press the print softkey in the upper right hand corner of the box. And that is how to save a file to USB.
