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.

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.
