Troubleshooting
Check Items When Trouble Occurs
Clearly abnormal measured value
o Measurement of compensation data may have failed.
Measure the compensation data again. For how to measure correction data,
refer to“CORRECTION page” on page 112.
o If the measured value is still abnormal even after taking the above measure,
turn off the correction function.
Perform resistance measurement of 100 to 1 k DUT by using the
E4980A/AL’s fixture after turning off OPEN/SHORT/LOAD on the
CORRECTION page and setting cable length to zero. If a measured value
close to the DUT’s value is displayed, there is the possibility of correction
failure or inappropriate cable length.
o When the MULTI compensation is ON, check that the channel and the
definition method of the LOAD standard value are selected correctly.
Saving to USB memory fails
Some USB memory does not work with the E4980A/AL. See the section on
