OPERATIONAL GUIDE

OPERATION

• Dip the probe in the sample to be
measured. An immersion level of 4 cm
(1 ½") is recommended.

• Do NOT immerse the probe handle.

• Do NOT wrench the probe or put
heavy objects on the cable. If the
cable is damaged, the meter needs
to be replaced.

• Wait for a few seconds for the display
to stabilize.

• Variations in readings or fading dis­play can indicate a weak battery.

CALIBRATION CHECK SWITCH

• Remove the rear cover (see also “Battery replacement”
section).

• Move the internal switch to the “TEST” position.

• The display should show 0.0±0.3°C (contact the near­est Hanna Service Center for recalibration, if necessary).

• To return to measure mode, move back the switch to
“MEAS” position.

• Reattach the cover while paying attention that the
gasket is in place before tightening the screws.

BATTERY REPLACEMENT

When the display fades, it is recommended to replace the
battery with a new one: unscrew the screws on the meter
back, remove the rear cover and change the battery, while
paying attention to its polarity.

Reattach the back cover while ensuring that the gasket is in
place before tightening the screws.

Battery should only be replaced in a safe area using one

1.5V AA alkaline type.
