• 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 calibration parameters
by pressing Clear and proceed with calibration from the current calibration point. The
instrument will keep all the confirmed values during the current calibration point.
• 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
symbol °C will blink on the display. Calibration cannot be confirmed in this
situation.
