5) For multi-point calibration repeat steps 2 & 3 with additional standards. Press

ESC to save the calibration, or press NEXT to view the calibration report.

Calibrate one point per range, up to 4.

Addition

al automatic conductivity calibration notes:

A maximum of one calibration point per range can be performed. If multiple

calib

ration points are used in the same range, the most recent one will replace

the previous one.

When the electrode is replaced, it is best to cl

ear the calibration to the factory

default values.

Rinse or immerse the probe before calibration and between samples with clean

water

(deionized water is ideal).

To protect from erroneous calibrations, the allowable tolerance is ±40% of the

factory defaul

t value.

For best results always begin with your

lowest calibration standard value,

followed by the next lowest, and so on.

Low conductivity standard solutions (less than 20 µS

) are unstable and are very

temperature dependent. As a result, reproducible calibration results are

challenging in lowest measurement range #1 (0.00 to 20.0 µS).

“2 Cell’ or “4 Cell’ electrode is automatically detected and

displayed on the measurement screen when connected.
