Submerge the ORP electrode 4cm (1½") into the sample to be tested
and wait a few minutes for the reading to stabilize.
Measurements within the ±699.9 mV range are displayed with 0.1
mV resolution, while outside this range the resolution automatically
switches to 1 mV.
For accurate ORP measurements, the surface of the electrode must be
clean and smooth. Pretreatment solutions are available to condition
the electrode and improve its response time (see "Accessories" section).
Notes:
• When the reading is out of range, the display will flash the closest
full-scale value.
• If using pH electrode while in mV mode, the meter will measure
the mV generated by the pH electrode.
MEM & MR FUNCTIONS
The instrument allows the user to store the current measurement (pH
and temperature, or mV and temperature) into internal memory by
pressing the MEM key. The MEMORIZE tag lights up on display.
Stored value can be recalled by pressing MR: the display will show
the value as long as the button is pressed, and the MEMORIZE
tag.
