Standardizing the Meter
for Millivolt Measurement
Millivolt measurement is used in electrode diagnostics,
titration, and in measuring oxidation/reduction (redox)
potential (ORP). ORP measurements indicate the
oxidizing or reducing capacity of a solution. You can
use ORP values to monitor and control solutions that
require a defined level of oxidants or reductants.
1. Immerse the electrode in standard solution.
2. If the display is not in mV mode: Press the [Mode]
mode key to toggle to mV mode.

3. Set a relative mV value:
Press the [Standardize] key.
4. When the signal has stabilized:
The meter automatically stores the measured value.
The current absolute mV value becomes zero relative
millivolts.
