11.1.

When do you need to calibrate?

•

It is recommended that after one year of field use, the user may verify the calibration using

appropriate calibration solutions mentioned in the original factory calibration certificate. The
user may order this solution when ordering the sensor.

•

The correct calibration solution and its batch number are also mentioned in the calibration

sheet of the sensor.

•

The user may also find the original factory calibration data including optical profiling (multi-

point calibration from) at:

https://analite.com.au/NEP-5000/CFG

11.2.

Two-point calibration requirements

•

When Auto-range mode is employed, it is recommended that user may calibrate all three

ranges at the same time using matching batch numbering solutions (so that batch to batch
tolerance in the turbidity standards are minimal).

•

When single range is being employed, the user may calibrate only the desired single range.
