5.3
Temperature Measurement
5.3.1
The instrument can be used to measure temperature
independently with the temperature probe.
5.3.2
When measuring temperature independently, remove
the pH electrode connected to the instrument.
5.3.3
Press the READ/AUTO key for 3 seconds to activate
continuous reading mode. Error code may appear on
pH display but will not affect the temperature reading.
5.3.4
Allow some time for the temperature reading to stabilize
before taking the measurement value.
5.4
mV Measurement
The instrument mV measuring function allows ORP, ion-
selective mV and others mV measurements.
5.4.1
Replace the pH electrode with the measuring
electrode.
5.4.2
Rinse the measuring electrode in distilled water and
switch on the instrument.
5.4.3
Rinse the measuring electrode in test sample solution
and then in another test sample solution and press the
READ/AUTO key.
5.4.4
The Wait indicator will flash momentarily until reading is
stabilized. The instrument will beep and the ‘AUTOLOCK’
indicator appears. Reading is established.
5.4.5
To disable the AUTOLOCK feature and allow continuous
reading, press and hold the READ/AUTO key for 3
seconds until a beep sound is heard. To resume to
AUTOLOCK mode, press the READ/AUTO key once.
5.4.6
If reading is erratic or unstable, the instrument will not be
able to AUTOLOCK the reading. This can be the result of
a worn-off or bad electrode.
