• Press CLR during calibration if you want to clear calibration
values. The instrument will display “ CLR” message and will
return to measurement mode.
• The calibration needs to be cleared when a new electrode is
attached to the meter.
• The instrument will display “ ----” on the primary LCD if it is
not calibrated or after all calibrations are cleared.
• Press RANGE to display the temperature reading on
the LCD during calibration.
ONE-POINT CALIBRATION
• Press CAL after first calibration point was confirmed. The instrument
memorizes the one-point calibration information and returns to
measurement mode.
• Press RANGE to display the temperature reading on
the LCD during calibration.
