OPERATIONAL GUIDE
POWER CONNECTION

Notes: These instruments use non volatile memory to retain the
pH, mV, temperature calibrations and all other settings, even when
unplugged. Make sure a fuse protects the main line.
ELECTRODE AND PROBE CONNECTIONS
For pH or ORP combination electrode connect to the BNC connector on
the back of the instrument.
For electrodes with a separate reference connect the electrode’s BNC

pH MEASUREMENTS
Make sure the electrode and the instrument have been
calibrated together before taking pH measurements.

approximately 3 cm (1¼”) into the sample to be
tested and stir gently. Allow time for the electrode
to stabilize.
The pH is displayed on the primary LCD and the temperature on
the secondary LCD.
