13.1. mV MEASUREMENT
Submerge the electrode tip (4 cm/1½”) into the sample to be tested and wait a few seconds for the
reading to stabilize. mV measurements are generated by the pH electrode and are displayed with 0.1
mV resolution.
13.2. RELATIVE mV CALIBRATION
1. Press
CAL
when the instrument is in mV measurement mode. The relative mV value and the
temperature values are displayed.
2. Use the / keys if you want to change the displayed relative mV value.
3. After the reading has stabilized and the relative mV offset is inside the offset window
(±2000 mV),
CFM
functional key is displayed. Press
CFM
to confirm relative mV calibration.
The instrument will return to measurement mode.
13.3. RELATIVE mV MODE
To enter relative mV mode, press
MODE
while in mV measurement mode. The Relative mV reading
will be displayed along with the absolute mV value and the current temperature readings.
The relative mV reading is equal to the difference between the absolute mV input value and relative
mV offset established in the relative mV calibration.
