4.6.1 RTD CALIBRATION BY DATA ENTRY
The RTD Calibrate menu allows you to adjust the intrinsic RTD reading to match an external reference thermometer by directly entering its reading. Only perform this procedure while the RTD under test is installed and currently measuring temperature.
To enter the current RTD temperature
Move the highlight to the RTD you want to calibrate (RTD1 or RTD2).
To access the RTD option list press 
.
Move the highlight to [User Cal] or [Factory] Cal then press ENT . This triggers the 
To enable numeric entry press 
(e.g., 72.0).
To recalibrate the RTD sensor ENT
. To verify the calibrated reading, go to [Diagnostics/Liquid Data] to check the current RTD output. Make 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.
4.6.2 ICE BATH RTD CALIBRATION
Use distilled, deionized water and ice mixture at 0ºC (32ºF) 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.
CAUTION: DO NOT ALLOW AN RTD SENSOR TO MAKE DIRECT CONTACT
WITH ICE DURING AN ICE BATH CALIBRATION.
To perform a 32ºF (0ºC) RTD Calibration:
Immerse RTD sensor in deionized water and ice mixture. Stir the mixture costantly.
Move the highlight by pressing
