Probe Compensation
To ensure good repeatable readings, particularly for low values of ESR, it may
be necessary to occasionally perform a simple Probe Compensation procedure.
This procedure is easiest to perform with the gold plated croc clips fitted.
1. Ensure the unit is switched off.
2. Press and hold down the
on-
test
button for about 5
seconds until the following
message is displayed*:
3. The unit will then ask you to
short the probes together (by
interlocking the jaws of each
croc clip). Then press the
on-
test button.
4. After a short delay the display
will
confirm that the
procedure is complete and
then switch off.
If the following message is displayed
then the probes may not have been
correctly shorted during the above
proecedure.
This message may also be
displayed if any of the probe connections are faulty.
It is useful to test the integrity of the probe compensation by measuring a fixed
resistor of 1Ω and 10Ω to verify the correct ESR reading respectively.
* NOTE: For the ESR70, the sound on/off mode will be entered while
holding the button down, keep the button held down and the unit will
proceed to the probe compensation mode.
