This document describes an ion selective meter called HI 96717, which features GLP mode, calibration mode, zeroing function, etc.
This document is the instruction manual for the Hanna Instruments HI 96717 Phosphate High Range ISM (In-Situ Meter). It provides preliminary examination steps, lists included accessories such as sample cuvettes and a 9V battery, and details technical specifications including range, resolution, accuracy, and environmental conditions. The meter utilizes an amino acid method adapted from standard water examination methods.

The instrument measures phosphate concentrations in a range from 10 to 30.0 mg/l.
One fresh battery lasts for around 750 measurements, depending on the light level.
A flashing value of the maximum concentration indicates an over range condition; you must dilute the sample and re-run the test.
No, you should not validate or calibrate with other standards as it will result in erroneous readings.
