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.
Ice Bath RTD Calibration
Use 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.
NOTICE
Sensor Damage
If RTD sensor makes direct contact with ice during an ice bath calibration procedure the
sensor may be damaged and the calibration results will be incorrect.
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 the pressing <Up/Down Arrow> to the
