Chapter 8 Error Compens
ation
A window such as the following will be displayed if the compensation process fails. If an error message is
displayed and compensation canceled (if you touch ), open compensation will be disabled.
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 measure-
ment will be performed.
• During the compensation process, be sure not to disturb the test cables or to move your hand near
them.
• Execute the guarding process.
