Error Messages
– If the last measurement is not valid error –230, “Data corrupt or stale” occurs.
A measurement is valid after it has been initiated. It becomes invalid when
either a reset occurs or any measurement parameter, for example frequency, is
changed.
– If the expected_value and resolution parameters are not the same as the
current expected value and resolution settings on the specified window, error
–221, “Settings conflict” occurs.
resolution A numeric value for the resolution. If it is unspecified the current
resolution setting is used. If a value is entered it should
correspond to the current resolution setting otherwise an error
occurs.

[a] The mnemonic DEF means DEFault. This is not equivalent to the DEFault parameter used in the command sub-systems. The parameters must
be entered in the specified order. If parameters are omitted, they default from the right. The parameter DEFault is used as a place holder.
Specifying DEF leaves the parameter value unchanged.
[b] When the measurement result is linear this parameter represents the number of significant digits. When the measurement result is
logarithmic 1 to 4 represents of 1, 0.1, 0.01 and 0.001 respectively.
FETC1:REL? DEF,2,(@2)
This command queries the upper window/
upper measurement relative measurement of
Channel B, using the current sensor range
and a resolution setting of 2.
