3.4 Relative mV Calibration

1. While in the measurement function, press MODE to

enter the mV mode. The mV indicator appears in the

upper right hand corner. See figure at right.

2. Press the CAL/MEAS key. The CAL indicator

appears above the primary display. The primary

display shows the relative mV reading and the

secondary display shows the absolute mV value.

NOTE: If you have never calibrated relative mV or if

the meter has been reset, the value shown

in the primary display is the same as the

absolute mV value.

NOTE: “R.” annunciator will appear once mV

calibration is performed, an indication of

mV offset.

3. Press the MI/▲ or MR/▼keys to enter the relative

mV value that matches your desired reading.

4. Press the ENTER key to confirm the reading and to

return to the measurement mode. The primary

display now shows the relative mV reading.

NOTES:

To view the mV offset value, use the SETUP mode

Program P3.1. See page 27 for instructions.

To reset all calibration and offset values in memory to the

factory default settings, use:

• In pH 300 meter: SETUP Program P 5.0. See page

34.

• In pH 310 meter: SETUP Program P 6.0. See page

37.
