Temperature Calibration
5.1
Calibration Procedure
1. Plug the Conductivity/Temperature sensor into the
Sensor
socket.
2. Place the sensor into a beaker of room temperature water, alongside a
good
quality
mercury
thermometer.
Stir
the
sensor
and
the
thermometer gently to ensure an even temperature throughout the
beaker.
3.
Select Temperature Calibration (
�
F1:Cal.
�
F3:Temp
).
4. The reading from the sensor is now displayed on the right of the
display, and the value you are going to set is shown on the left. For
example…
�
25.0
�
20*0
o
c
��
:Set
F1:Cal.
5. When the reading on the right has stabilised, press the
and
keys until the reading on the left shows the same temperature as the
mercury thermometer.
6. Press the
key to calibrate the temperature readout.
Alternatively, press
to quit and retain the current calibration
settings.
The
�
will now be replaced by a decimal point, if calibration was
successful.
Alternatively, press the
key to abort temperature calibration.

Calibration Notes
1. Temperature calibration information is retained in memory when the
WP-84
is switched off, even when the battery is removed. This
information can be recalled or printed later using the GLP function (see
section 7).
2. Temperature does not need to be re-calibrated unless the sensor is
replaced or the meter is initialised.
