1. Press to display ～.
2. Slide the slide cover up using the slide knob. Next,
insert the red test lead to V and the black test lead
to COM of the voltage measurement terminal.
3. Switch between the auto range and the manual range
as necessary.
4. Carefully contact the test leads to a circuit.
･ Just after suspension of input, or when modes are
switched under no input, the counter would not
become zero for about 10 seconds. This is normal
and simply reflects the workings of the internal
circuit. But you can measure with guaranteed
accuracy before the counter becomes zero.
･ Depending on ambient temperatures, the counter
would not become zero under no input, if this
happens, press
HOLD
and then press
0ADJ/RESET
to perform a zero-cancel correction. (2.5.2: Zero-
cancel correction function)
･ During a f.s. input, the measurement response speed
is about 250 ms during rise (0% to 90%) and about
500 ms (100% to 10%) during fall (2.2.5, Figs. 1
and 2).
･ The AC V mode does not allow measurement of DC
waveforms, full-wave rectification waveforms, half-
wave rectification waveforms, or DC+AC
waveforms (See 1.5: Modes).
･ Every range will display up to 125% of the range,
however, only the range from 10% to 100% can be
displayed with guaranteed accuracy.
･ At any range, gross errors may occur at 1% or
below of the range, whose accuracy is not
guaranteed, as a result of internal corrective
calculations.
