MEASUREMENT PROCEDURES
mV Measurement (± 499 mV)
mV measurement range is from -499 mV to +499 mV with a pH probe.
1. Follow Step 1 in the pH Measurement section (page 30) to clean and
soak the probe.
2. Press
POWER
to turn the meter on. Press
MODE
to select mV mode.
3. Follow Steps 3-5 in the pH Measurement section (page 30) to obtain
a reading.
4. Press
MODE
to switch between mV and pH.
ORP (mV) Measurement (± 1999 mV)
Oxidation Reduction Potential (ORP) measurement range is -1999 mV to
+1999 mV. Use an ORP probe for measurement:
1. Follow Step 1 in the pH Measurement section (page 30) to clean and
soak the probe.
2. Press
POWER
to turn the meter on. Press
MODE
to select
mV measurement.
3. Follow Steps 3-5 in the pH Measurement section (page 30) to obtain
a reading.
Note...
There is no need to take temperature compensation into consideration
when measuring ORP.
