TROUBLESHOO

TING GUIDE

SYMPTOMS

PROBLEM

SOLUTION

Slow response/excessive drift

Dirty pH electrode.
Dirty reference junction.

Soak the electrode tip in

HI7061

solution for 30 min.

and then clean the electrode.
Soak in

HI7074.

Readings fluctuate up and
down (noise).

Clogged/dirty junction.
Low electrolyte level (refillable
electrodes only).

Clean the electrode.
Refill with fresh solution (for
refillable electrodes only).

The LCD displays “_” during
measurements (pH, mV, mV
Rel or ISE).

Out of range in the appropri-
ate scale.

Check to see if the pH bulb
and reference junction are in
the solution. Make sure the
sample is in the specified
range.Check the electrolyte
level and the general state of
the pH/ORP or ISE electrode.

IMPORTANT

After performing any of the cleaning procedures, rinse the electrode thoroughly

with distilled water, refill the reference chamber with fresh electrolyte (not necessary for gel-filled
electrodes) and soak the electrode in

HI70300

HI80300

Storage Solution for at least 1 hour

before taking measurements.

Out of range in the mV scale.

Dry reference junction.

Soak in

HI70300

Storage

solution for at least one hour.

The instrument does not work
with the temperature probe.

Out order temperature probe.

Replace the probe.

The meter fails to calibrate or
gives faulty readings.

Broken or out of order
electrode.

Replace the electrode.

Explicit warnings are dis-
played during calibration.

Dirty/broken electrode,
contaminated buffers.

Follow displayed instructions.

The electrode condition is not
displayed after calibration.

Only one-point calibration has
been performed.

Perform at least a two-point
calibration.

The instrument does not
start up.

Internal or software error.

Restart the instrument using
the power switch or unplug
adapter.If the error persists,
contact your local Hanna
Instruments Office.
