To enter Rel mV operation press 2nd and Mode from mV measurement.

• Place the ORP electrode into solution or

standard.

• Wait for a stable mV to be displayed.

• Press CAL when the instrument is in

RELATIVE mV measurement mode. The

relative mV value is displayed on the

primary LCD and the absolute mV value

on the secondary LCD.

• Use the ARROW keys to change the displayed relative mV value.

• When the reading is stable, in mV range and the Relative mV offset

is inside the offset window (±2000 mV), “CFM” tag blinks.

• Press CFM to confirm the relative mV calibration. The instrument will

return to measurement mode.

• If the absolute mV reading is out of range or the Relative mV offset

is out of the offset window, “WRONG” tag will blink. Verify sensor tip

is fully submersed in solution and electrode is fully plugged in.

However, temperature correction during pH measurements provides

values at the temperature of measurement. Actual pH values may differ

if measured at two different temperatures.
