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 recalibrated unless the Temperature sensor
is replaced or the meter is initialised.
5.3 Calibration Messages
1. If a temperature calibration has been successfully performed, the 901-PH
will display the offset value of the sensor and then return to Temperature
mode. For example…
Temp Cal. OKTemp Cal. OK
then:
Offset=1.0Offset=1.0
oo
cc
The " ∗∗ " is replaced by a decimal point in the Temperature reading to
indicate that Temperature is correctly calibrated.
2. If a temperature calibration has failed, the 901-PH will display the failed
offset value of the sensor before returning to Temperature mode. For
example…
Temp Cal. FailTemp Cal. Fail
then:
Offset=11.0Offset=11.0
oo
cc
Note that " ∗∗ " replaces the decimal point in the Temperature reading to
indicate that Temperature is not correctly calibrated.
