CAUTION In ammeter function, range switching is always
manual, and selected by the rotary switch.
See precautions to be observed in the current
measurement section.
· Pressing the MAN RANGE/AUTO RANGE key changes to the
manual ranging mode, and the range selected can then be incre-
mented by briefly pressing the same key. (Hold it down for not more
than two seconds.)
· Holding the MAN RANGE/AUTO RANGE key down for more than
two seconds re-activates autoranging mode.

· Connect the black lead to the terminal marked COM, and the red
lead to the terminal marked VW .
· Set the rotary switch to the V
DC
position.
· Apply the test prods to the points across which the voltage is to
be measured, and read the result directly from the display. This
shows the measurement units (mV or V) and the polarity ( - for
negative polarity and nothing for positive polarity).
· Accuracy, resolution, and input resistance: see detail specifica-
tions section 2.2.

example in the line scanning circuits of television
sets), use a type HA0902 filter probe.
