Ice Bath RTD Calibration
Use distilled, deionized water and ice mixture at 0°C (32°F) equilibrium for an ice bath. Ensure
temperature with a reference thermometer. Siemens can not assume responsibility for the
incorrect design, construction or operation of an Ice Bath.
Do not allow an RTD sensor to make direct contact with ice during an ice bath calibration
procedure.
To perform a 0°C (32°F) calibration:
1. Immerse RTD sensor in deionized water and ice mixture. Stir the mixture constantly.
2. In the [RTD Calibrate] menu move the highlight by pressing <Up/down Arrow> to the RTD
3. To access the RTD option list press <Right Arrow>. Move the highlight to [User Cal] then
4. When you are sure that the RTD Sensor is at 0°C (32°F), press <ENT> to recalibrate the
5. To verify the calibrated reading, go to Dual Path Flow [Diagnostic Data/Liquid Data] menu
7.11 Reflexor
Reflexor is one of the operating modes available on certain SITRANS F 1010 models. The
Reflexor operating mode utilizes Doppler flow detection along with digital signal processing
techniques to successfully measure flow under conditions that may not be suitable for transit-
time flow measurement. The Reflexor samples the flow stream as it detects Doppler shift. It
converts the Doppler shift information by use of Fast Fourier Transform (FFT) and filters the
96
thermometer (e.g., 72.0).

sure that it coincides with the reading of the reference thermometer. Repeat for the other
RTD, if necessary.
Note
Factory Calibration provides an additional prompt after a new temperature is entered: [Are
you Sure? No Yes]. It is recommended that you use [User Cal] to avoid alteration of preset
factory calibration.
