• 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 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.
