Operational Guide

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 con rmed values during the

current calibration.

If the temperature reading is out of

the de ned temperature range of the

bu er (0 to 45 °C), the “Wrong Bu er

Temperature” error message will be

displayed, and the temperature symbol

will blink on the display. Calibration

cannot be con rmed in this situation.
