• pH-the slope and offset values are shown alternating with the
deviation (in %) and calibration temperature.
• ORP-the measured mV value and calibration temperature are
shown.
• Conductivity-the cell constant and calibration temperature for each
standard are shown.
Set the calibration reminder
The calibration reminder can be set between 0 to 23 hours or 1-7 days
(default 1 day). The display shows the remaining time to the new
calibration.
Note: When 0 days is selected, the calibration reminder is turned off.

Resolution
Select the resolution: 1, 0.1, 0.01 (default) or 0.001
Measure
Stability—select By stability Criterion: Fast (variation <
0.02 pH in 6 s), Standard (variation < 0.01 pH in 6 s) or Strict
(variation < 0.002 pH in 6 s). In continuous—enter the time
interval for the In continuous Acquis. interval (data storage or
printing data). By time—enter the time interval for data storage
or printing data.
Display mV
Display mV—select YES or NO to show mV.
Limits
Limits—select YES or NO. YES: Enter the upper and lower
limits. An acoustic warning appears when the measurement is
out of limit. The report output shows an A next to the
measured value when the measurement was out of limit.
Isopotential Isopotential—change the Isopotential pH value in Data
introduction. Select Calculate to calibrate the probe again.
3. Push
to start the measurement.
Note: If the measurement is not stabilizing after 120 seconds, the meter turns
automatically into the continuous measurement mode.
