5. Temperature Calibration
5.1 Calibration Procedure
1.
Switch the
901-C
on and select Temperature mode (see section 2).
2.
Plug the temperature sensor (Part No 121245) into the
Temp.
socket.
3.
Place the sensor alongside a good quality mercury thermometer into a
beaker of room temperature water. Stir the sensor and the thermometer
gently to ensure an even temperature throughout the beaker.
4.
When the reading has stabilised, press the
key.
5.
The
901-C
now enters temperature calibration. For example…
Enter True Temp

keys until the display shows the same temperature as
the mercury thermometer.
7.
Press the
key to calibrate the temperature readout.
Alternatively, press the
key to abort temperature calibration.
5.2 Calibration Notes
1.
Temperature calibration information is stored in memory when the meter is
switched off, even when the power supply is removed.
2.
Temperature does not need to be re-calibrated unless the Temperature sensor
is replaced or the meter is initialised.
