6.5 CALIBRATION – Analog Outputs

6.5.1 Purpose

Although the analyzer analog outputs are calibrated at the factory, they can be trimmed in the field to match the reading from a standard milliammeter. Both the low (0 or 4 mA) and high (20 mA) outputs can be trimmed.

6.5.2 Procedure

1.Connect a calibrated milliammeter across the output you wish to calibrate. If a load is already connected to the output, disconnect the load. Do not put the milliameter in parallel with the load.

4.The analyzer will simulate the low output current. Change the value in the display to match the reading from the milliammeter.

5.The analyzer will simulate the 20 mA output current. Change the value in the display to match the reading from the milliammeter.

6.If the calibration was successful, the screen at left will appear.

7.If the user entered value is more that ±1 mA different from the nominal value, a possible error screen will appear. To force the analyzer to accept the calibration, choose Yes.

8. To return to the main display, press MENU then EXIT.
