This indicates a measurement fault. It appears in cases of a disconnected test lead, poor
probe contact or when the test object’s measured value is far above the measurement
range.
The measurement fault signal is output from the ERR terminal of the EXT I/O connector.
The following causes should be considered:
• A test lead may not be connected to the test object
• Test object resistance may be too very large for the measurement range
Example: Measuring 20

with the 300 m

range
• Any of the SOURCE-H, SOURCE-L, SENSE-H or SENSE-L leads may be discon-
nected or poorly connected
• The probe may have a high contact resistance
See " Measurement Fault Detection"(

p.36)
• The contact failure circuit protection fuse may have blown due to test lead damage,
excessive wear, or impurities.
