7.13 Resistive Temperature Device (RTD) Calibration
The [RTD Calibrate] menu appears on all SITRANS 1010 models. Use this menu to calibrate
Temperature Sensors to an external standard. It is important to note that Siemens RTD
temperature sensors are factory-calibrated for high accuracy. We recommend that before
deciding to perform the calibration, check the current RTD reading in the [Diagnostics Data]
menu. You may find that you do not 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 0°C (32°F) 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 temperature sensors,
changing the sensor/connector orientation established during the procedure may void the
calibration.
1. From the [Meter Facilities] menu scroll to the [RTD Calibrate] menu.
2. To access the [RTD Calibrate] menu press <Right Arrow>.
