If the meter is connected with Pt1000 temperature electrode, user should set temperature electrode to
be Pt1000, otherwise, set temperature electrode to be RT2252.
Direct press “Model Pt1000” or “Model RT2252” on screen, and press “ENTER” button to
confirm.
The meter sets temperature electrode and to be back to starting working state. Press “CANCEL”
button or “X” to exit temperature electrode setting menu, the meter is back to starting working state.
If selected temperature electrode is “Pt1000”, the meter displays “SETUP RO” button in menu, press
this button to set resistance of Pt1000 temperature electrode at 0℃. Generally, the resistance value of
Pt1000 temperature electrode under 0℃ is 1000Ω, considering the technics and material used, the
resistance value of Pt1000 temperature electrode at 0℃ is not exactly 1000Ω. At this time, in order
to ensure measuring precision, it is neccessary to reset R0 value according to nominal resistance
value. Press „SETUP R0‟ key and input R0 value of actual nominal resistance.
The measuring result will be different everytime when the data is amended. If you are not able to get
R0 resistance value in using Pt1000 electrode at 0℃, please do not amend the data at will.
4.6 Calibrating mV zero point
To ensure high precision, please calibrate mV zero point only after you switch on
the meter in
half an hour
Press “SETUP” button, select “Zero(mV)”, press “ENTER” button to enter mV calibration
mode. The meter displays “Adjust zero(mV), Enter?”. Press “ENTER” button to confirm,
otherwise, press “CANCEL” button to be back to starting working state.
