Pgen Output Trim (Pgen 1 And Pgen 2); The Rtd Calibrate Menu (Optional) - Siemens SITRANS F Operating Instructions Manual

Section 4
If the multimeter reading does not match, use the numeric keys to type in the multimeter read-
ing.
ENT
Press to register setting. This adjusts the meter's DAC (digital-to-analog converter) so
that a 2.00 Volts output corresponds with 2.00 Volts on the multimeter.
Recheck the multimeter to make sure that it is now reading 2.00 Volts.

4.5.4 PGEN OUTPUT TRIM (Pgen 1 and 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 signal and reference terminals of the pulse rate output un-
der test.
Move the highlight to the port to be tested by pressing
to move the cursor to Trim @ 1kHz.
ENT
Press . This triggers a 1 kHz pop-up window. The frequency counter should now be read-
ing 1 kHz.
If the frequency counter reading does not match, use the numeric keys to type in the frequency
counter reading.
ENT
Press 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.
Recheck the frequency counter to make sure that it is now reading 1 kHz.

4.5.5 THE RTD CALIBRATE MENU (optional)

The RTD Calibrate Menu appears on some 1010P models. Use this menu to calibrate the 1011 Series
RTD Temperature Sensors to an external standard. It is important to note that Controlotron RTD tem-
perature 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 cali-
bration, which can be accomplished either by data entry of the current RTD temperature or by a 32
0
(0 C) 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.
