• If the measured offset isn’t within the preset limits (±45 mV), the meter will display the
message
“Buffer Contaminated”
alternatively with
”Electrode Dirty/Broken”
.
• If the computed slope isn’t within the preset limits, the meter will display the message
“Wrong
Slope”
. If the slope is too high the symbol
will be displayed. If the slope is too low the
symbol
will be displayed.
• If the
“Wrong Old Slope”
error message is displayed, an inconsistency exists between the
current and the previous (old) calibration. Clear the previous calibration by pressing
Clear
and
proceed with calibration from the current calibration point. The instrument will keep all the
confirmed values during the current calibration.
• If the temperature reading is out of the defined temperature range of the buffer (0 to 45 °C),
the
“Wrong Buffer Temperature”
error message will be displayed, and the temperature
symbol will blink on the display. Calibration cannot be confirmed in this situation.
