19. TROUBLESHOOTING GUIDE

SYMPTOMS

PROBLEM

SOLUTION

Slow response/excessive
drift.

Dirty pH electrode.

Soak the electrode tip in

HI7061

cleaning solution for 30 minutes.
Refill with fresh fill solution.

Reading fluctuates up and
down (noise).

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

Soak the electrode tip in

HI7061

cleaning solution for 30 minutes.
Refill with fresh fill solution.
Check cable connection to meter and
verify protective cap is off.

While in pH reading mode,
-2.00 or 16.00 pH is
displayed blinking.

Reading out of range.

Check cable connection to meter and
verify protective cap is off.
Check the quality of the sample.
Clean the electrodes.
Refill with fresh fill solution.

The meter does not accept
the pH buffer solution for
calibration.

Broken pH electrode.

Replace the electrode or contact the
vendor.

The pump calibration can’t
be performed

Broken pump tubing.
Wrong or contaminated
pump calibration solution.
Broken pH electrode.

Verify tubing, valve, syringe are intact
and solution passes when pump is
primed and no air bubbles are present.
Check the pump calibration solution.
Verify electrode is calibrated in fresh pH
buffers.
Prepare another standard, prime the
pump and restart the calibration.

The temperature probe is
connected, but the meter
displays “MTC”.

Broken temperature probe. Replace temperature probe.
