Hanna Instruments Intercom System HI 982401 User Manual

The BNC connector is protected
against vapors and humidity by a wa-
terproof sheath.
• Slide the protective sheath down.

Connect the HI  3214P/2 ORP elec-
trode to the BNC connector and
then slide up. Make sure the con-
nector is completely covered.

• Do not be alarmed if white crystals appear around the

electrode protective cap. This is normal with ORP elec-
trodes and they dissolve when rinsed with water.

• When not in use, rinse the electrode with water and store

it with the protective cap.

• If the electrode has been left dry, soak the tip in HI 70300

storage solution for at least one hour to reactivate it.

• Turn the meter on.
• Remove the protective cap from the

ORP electrode and immerse the tip
(4 cm/1½”) in the sample.

• The LCD will show the ORP value

measured in mV unit. Allow the read-
ing to stabilize and HI 982401 will
start continuous monitoring.

Note: to prevent damages to the meter,

remove the ORP electrode from
the sample before turning the
meter off.

• To access the MEASURE/SET switch

and the setpoint adjustment trimmer,
unscrew the 4 screws on the meter
back and remove the rear panel.

• Move the switch to the SET position

(left).
