3.2.2 With Temperature Probe (with Curve Selection)
In the event the temperature probe has drifted too far from
its original characteristic due to age and use or if the probe
is being replaced, it may be a good idea to match the
probe to the best curve. There are 3 curves programmed
in the unit. To choose the curve, proceed as follows :-
1 Connect your temperature probe to the meter. Dip the
probe in a constant temperature bath or a liquid whose
temperature can be checked with a thermometer known to
be accurate. For best accuracy, place the probe and
thermometer in a constant temperature bath.
2 Make sure that the meter is in the pH measurement mode.
Press CAL key and the pH value flashes to indicate that
you are in the CAL mode.
3 Press MODE key. The display will show the temperature
of measured liquid.
4 Press MODE key. Each press will take you through one
curve. Choose the curve which gives you a reading closest
to the actual value (of the bath or thermometer).
