General Description

Specifications

Display Code Guide

This indicates that the meter is in a
ready state and zeroing can be
performed.
Sampling in Progress. This prompt
appears each time the meter is
performing a measurement.
This indicates that the meter is in a
zeroed state and measurement can
be performed.
A zero reading was not taken. Insert
a sample before adding reagent and
press ZERO.
Under range. A blinking "0"
indicates that the sample absorbs
less light than the zero reference.
Check the procedure and make sure
you use the same cuvet for reference
(zero) and measurement.
Over range. A flashing value higher
than the maximum concentration
readable (see specifications) indicates
that the sample absorbs too much
light, meaning that the concentration
is too high. Dilute the sample.
Light over range. The cuvet is not
inserted correctly and an excess
ambient light is reaching the detector.
If the cover is properly installed,
then contact your dealer or the
nearest Hanna Customer Service
Center.
Light under range. The zero sample
is too dark for proper zeroing. If
this is not the case, contact your
dealer or the nearest Hanna
Customer Service Center.
The "V" indicates that the battery
voltage is getting low and the battery
needs to be replaced.
This indicates that the battery is dead
and must be replaced.

Note:

 once this indication is

displayed, the meter will lockup.
Change the battery to restart.
