MEASUREMENT PROCEDURE

To compensate the meter for the sample turbidity or color, the measurement takes place in two
phases. First, the meter is zeroed using the unreacted sample. After the reagents are added the
reacted sample is measured.
Important note:

Free and Total Chlorine have to be measured separately with fresh unreacted

samples if both values are requested.

• Turn the meter on by pressing ON/OFF.

The display briefly shows all tags on.

• Press RANGE/GLP/ to change the range.

The range can be changed any time when the
instrument is in

measurement mode

.

The selected range is memorized and the selection
remaines unchanged at power off or when the
battery is removed.

The HI 96710 can measure pH when range P1 is selected, Free Chlorine when range P2 is
selected or Total Chlorine when range P3 is selected. To change the active range follow the
procedure:
• Turn the meter on by pressing ON/OFF. The

display briefly shows all tags on.

• After startup, the range identification number is

displayed on the secondary LCD as P1, P2 or P3.
