15. Initialising the WP-80
If the calibration settings of the
WP-80
exceed the allowable limits, the
unit may need to be initialised to factory default values. This action may
be required if the electrode is replaced.
To initialise the
WP-80
:
1. Switch the
WP-80
off.
2. Press and hold the
key while switching the
WP-80
back on.
3. The following messages should be displayed:
Initialized
MUST ReCalibrate
then :
WP80s V3.5 S1234
pH mV Temp.
(The “s” after
WP-80
is shown when the RS232 serial port option is
fitted)
4. The meter then displays pH and Temperature. Note that the decimal
points have been replaced with a
∗
, to indicate that the unit requires
recalibration.
Note:
When the
WP-80
is initialised, the automatically recognised
buffers are re-set to pH4.00, pH6.88 and pH9.23. See section 14 if
you prefer to use pH7.00 instead of pH6.88 and pH10.00 instead
of pH9.23.
