Voltage measurement:
･
Check that the test leads are fully connected.
･
Check that the frequency of the measured circuit is within
the range provided in the specifications.
･
Check that the proper steps have been taken, according to
the procedure described in 2.5.1: Auto-zero adjustment
function and 2.5.2: Zero-cancel correction function.
･
Check that you're using the proper mode. (See 1.5:
Modes.)
･
Check that the peak value is below the circuit dynamic
value provided in the specifications. (To check
transitional peak value, see Notes in 2.2.4 and 2.3.4: Peak
hold measurement.)
･
Check that the crest factor (peak value / RMS value) is
below the circuit dynamic value provided in the
specifications.
･
Check that the battery warning annunciator is off.
Frequency measurement:
･
Check the waveform. Some special frequencies can't be
measured, such as those of inverters.
･
Check that the input value corresponds to 10% or more of
the range.
