6.2 Measurement using
Kelvin probes
An example how to perform testing using the two
Kelvin probes. This example describes the perfor-
mance if you only want to know if the test object pass
a preset value and you do not need to store the test
results.
1]
Select LOG function "OFF", and set P/F value
(see section 4.6 and 4.7).
2]
Attach the test cables with Kelvin probes (2 x
1.3 m) one with a trigger, to MOM2.
3]
Turn the function selector to desired posi-
tion.
4]
Hook the instrument to your belt or use the
strap.
5]
Press and hold the two Kelvin probes to the
test object and pull the trigger.
