Taking A Conductivity Measurement - GE AutoSigma 3000 DL Technical Reference, Operating Manual

Operation
5.6 Taking a conductivity
measurement
Ensure the instrument is on and in Measurement
mode see section 5.1. Carry out set probe routine as in
sections 5.4 and 5.5.
With the probe in air the display should be as below.
With (H) if 500 kHz is selected or (L) if 60 Hz is select-
ed. The battery indication should show some content,
and if the icon shows empty new batteries should be
fi tted.
5 - 8
The instrument is now ready to take a measurement.
The probe should be at the same temperature as the
material to be measured, if there is a difference the
probe and STD blocks should be allowed to stabilise
on the surface of the material to be measured. The set
probe routine should then be carried out at the tem-
perature the measurements are to be taken at.
Place the probe on the surface of the material to be
measured, making sure it is as fl at as possible on the
surface and not overhanging the edge, the display will
then indicate the conductivity in the units selected.
If the material's ambient temperature drifts beyond
+/–3 °C the display will indicate that a probe set rou-
tine is advisable. (SET will appear on the bottom line
of the display).
If measurements are to be carried out on round bars
or curved surfaces the correct probe and guide should
be used for ease of use and accuracy of results.
