Table of Operations When Measurement Errors Occur
Operations When Measurement Errors Occur
Operations When Measurement Errors Occur
Table D-1 shows the LCD screen indications, GPIB output, and the parameters and
interface signals that become active when any of the following items is detected.
• Overload
(Detected for ranging failure caused by DUT coming loose during measurement, etc.)
•R
dc
limit deviation
(Detected when the R
dc
measurement result does not fall within the limit range.)
• Simultaneous detection of overload and R
dc
limit deviation.

*1. All measurement values of parameters 1 to 4 (impedance measurement), measurement signal level monitor, and
R
dc
measurement.
*2. Ovld lights up red in the instrument status area at the bottom of the display.
*3. Overload is not detected for R
dc
measurement.
*4. The measurement result is indicated as usual, but the indicated value may have been measured in a condition of
improper contact.
*5. The measurement result is indicated as usual, but the characters are displayed in red.
*6. The measurement result is read out as usual, but the readout value may have been measured in a condition of
improper contact.
