7.11 RTD Calibration
5. Press <ENTER>to register setting. This adjusts the flow meter's DAC (digital-to-analog
converter) so that a 1 kHz output corresponds with 1 kHz on the frequency counter.
6. Recheck the frequency counter to make sure that it is now reading 1 kHz.

RTD Calibration
Resistive Temperature Device (RTD) Calibration
The RTD Calibrate Menu appears on all SITRANS F 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/Liquid Data] menu. 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 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>.
