3. Press enter repeatedly to view all previous calibration data,
starting from the first range till fourth range.
The meter will display the calibration value of that particular range
provided calibration is performed. If any of the range is not being
calibrated the upper display shows “---“.
Range 1 has the lower display showing “r1”, range 2 will display
“r 2” and the following ranges respectively.
The meter displays the effective cell constants through the
respective ranges and also the calibrated value. The cell constant
is adjusted according to your calibration options. This will serve
as an indicator to the probe’s efficiency.
)
Cell constants of electrode will degrade with time and usage. You
can use this feature to prompt you the need for a new probe prior
to total failure. Recommended value as an indicator for a
replacement of probe is either 0.60 or 1.40 (±40% of 1.000).
