4.7 Open Circuit Compensation

4.7.5 When an Error Message Appears and Compensation Has
Stopped
4.7.6 Clearing Compensation Data
When an error message appears and compensation has stopped, open circuit
compensation is turned OFF.
The open circuit compensation process is quite sensitive to noise - both
noise originating externally and induced noise. Therefore, if open circuit
compensation has been interrupted with a fault, you should check the
following points before starting the compensation process again:
Check that the test cables are properly connected.
Check that nothing is connected to the test cables. (Open circuit
compensation cannot be performed while any test sample is connected to the
test cables.)
Check that the test leads are arranged as closely as possible to their
configuration in which measurement will be performed.
During the compensation process, be sure not to disturb the test cables or to
move your hand near them.
Stopping during open-circuit compensation may result in failure to finish a
reading. This is thought to be due to the influence of outside noise, so please
execute the guarding process as a precaition. (For details, refer to Section
5.2, "Testing High Impedance Elements".)
From the Open circuit compensation screen, press the key, and the
display will revert to the Initial screen with the compensation data cleared.
