Model UT804: OPERATING MANUAL
D. AC Current (AC+DC measurement is available)
Range Resolution
400 A 0.01 A
4000 A 0.1 A
40mA 0.001mA
400mA 0.01mA
10A 0.001A
Remarks:
l Display:
a) True rms are valid from 10% of range to 100% of range
b) AC crest factor can be up to 3.0.
c) A residual reading of 80 digits with test leads shorted, will not affect stated accuracy.
d) The accuracy guarantee range 10%-100%.
e) When making AC+DC measurment, the accuray need to add(1%+35 digits)of reading based on the above table.
l At 10A range:
a) When the measured current is
b) When the measured current is between >5A-10A, continuous measurement
than 15 minutes.
