5.
The calibration range indicator will appear on the display for each range
that is calibrated during a power on cycle.
L
Low Range, 84μS/cm
M
Medium Range, 1413μS/cm or 3000 ppm SaH
H
High Range, 12,88mS/cm (12,880μS/cm)
NOTE: Each time the calibration mode is entered all calibration range
indicators will be cleared, but only the calibration data for the currently
selected range will be replaced. In the conductivity/TDS modes, the
calibrations for the other two ranges will be saved even though the
indicators for those ranges are no longer displayed. Calibration of all
three ranges must be performed during one power on period for all three
calibration range indicators to be displayed.
Reset Calibration Data
Follow this procedure to clear all calibration data from the meter. Resetting
the calibration data may be necessary when new calibration solutions are
used or accuracy of measurements is in question.
1.
Turn off the meter.
2.
Press and hold the CAL and MODE buttons.
3.
Momentarily press the ON/OFF button, as soon as they display comes
on, release all 3 buttons.
4.
The display will show "dFLt rSt" (default restart) and all of the
calibration data will be erased. If "dFLt rSt" does not appear, retry the
procedure.
5.
Proceed to the calibration routine for pH and Conductivity.
