If the multimeter reading does not match, use the numeric keys to type in the multimeter read- ing.

Press ENT to register setting. This adjusts the meter’s DAC (digital-to-analog con- verter) so that a 2.00 Volts output corresponds with 2.00 Volts on the multimeter.

Re-check the multimeter to make sure that it is now reading 2.00 Volts.

4.5.4 PGEN OUTPUT TRIM (Pgen 1 & Pgen 2)

(Note: Can be trimmed to within 1.25 Hz of nominal.)

To calibrate a pulse rate output (Pgen1 or Pgen2):

Connect a frequency counter to the supply and return terminals of the pulse rate output under test.

Move the highlight to the port to be tested

, press

, then press

to move

the cursor to Trim @ 1kHz.

 

 

 

Press ENT . This triggers a 1 kHz pop-up window. The frequency counter should now be reading 1 kHz.

If the frequency counter reading does not match, use the numeric keys to type in the frequency counter reading.

Press ENT to register setting. This adjusts the meter’s DAC (digital-to-analog converter so that a 1 kHz output corresponds with 1 kHz on the frequency counter.

Re-check the frequency counter to make sure that it is now reading 1 kHz.

4.6THE RTD CALIBRATE MENU (optional)

The RTD Calibrate Menu appears on all 1010N models. Use this menu to calibrate the 991T or 1011TN RTD Temperature Sensors to an external standard. It is important to note that the RTD temperature sensors are factory-calibrated for high accuracy. We recommend that before deciding to perform the calibration, check the current RTD reading in [Diagnostics/Liquid Data]. You may find that you do not even need to calibrate the sensor. In any case, make sure that the temperature reading stabilizes before proceeding further. The RTD Calibrate menu allows you to perform an external calibration, which can be accomplished either by data entry of the current RTD temperature or by a 320F (00C) Ice- Bath procedure. You can switch between the intrinsic and external calibration modes at any time.

NOTE: If you perform an external temperature calibration, you should mark and record the location of each connector and sensor-cable. Once you have re-calibrated the tem- perature sensors, changing the sensor/connector orientation established during the procedure may void the calibration.
