TING GUIDE

6. TROUBLESHOOTING GUIDE

IMPORTANT:

After cleaning rinse the electrode thoroughly with distilled water, refill the reference

chamber with fresh electrolyte and soak the electrode in

HI70300

HI80300

Storage solution for at

least 1 hour before taking measurements.

Symptoms

Problem

Solution

Slow response / Excessive drift

Dirty pH electrode

Soak the electrode tip in Hanna

HI7061

General cleaning

solution for 30 minutes and
then follow the Cleaning
Procedure.

Reading fluctuates up and down
(noise).

Clogged/dirty junction
Low electrolyte level

Clean the electrode. Refill with
fresh electrolyte.

Display shows full-scale value
blinking.

Reading out of range

Check that sample is within
measurable range.

Display shows "Clean electrode"
blinking.

Difference between new and
previous calibration has
been detected.

Clean electrode and recalibrate.
If the problem remains, check
the buffer solutions.

Meter fails to calibrate or gives
faulty readings.

Broken pH electrode

Replace electrode.

Error messages are displayed
during pH calibration procedure.

Wrong or contaminated
buffer, electrode dirty or
broken

Check that buffer solution is
correct and fresh.

Meter shuts off.

Dead batteries
Auto-off feature is enabled:
in this case, meter shuts
off after selected non-use
period.

Replace the batteries.
Turn the meter on.

"Errxx" message at start up

Internal error

Contact your local Hanna
Instruments Office.

The instrument does not start
when pressing the

ON/OFF

key.

Initialization error

Press and hold down the

ON/OFF

key for about 20

seconds or remove and replace
the batteries.
