IMPORTANT NOTES:
1. Meter allows a tolerance range of ±40% of its calibration standard.
If the calibration standard is detected out of the tolerance range
during the calibration mode, the meter will prompt by the toggling of
the secondary display continuously between various calibration
standard values. An error message “ERR” will be displayed for 3
seconds if you attempt to calibrate with a solution whose value is
outside the tolerance range.
For instance: For 1413 µS conductivity calibration standard, 40%
tolerance is from 848 µS to 1978 µS.
2. All new calibration data will over-ride existing stored calibration data
for each measuring range calibrated.
3. It is important to use new conductivity calibration standards.
4. Low conductivity standard solution (less than 20 µS /cm) cannot be
available easily. Such low conductivity standard will be
contaminated as soon as it is exposed to the air. It is therefore for
this reason automatic calibration in the first measurement range
(0.00 to 20.0 µS /cm) of this meter is not possible.
