Displays ac rms voltage measurements as the log of
the ratio of the input voltage
to a 1 mW reference at
6000. Readings equal 20Xlog(VinputlVret)' where
Vinput is the input voltage and V
ret
is 0.7746 V. With
zero input, the readout displays
·OVER."
Selects or deselects continuity. If the resistance between
the probes
is less than 10 n, the instrument produces an
audible tone. The readout shows either 'SHORT <
10 !2" or 'OPEN > 10 0." The tone responds to
continuity within about
100 ms.
Continuity operation
is not affected by AUTO, UP,
DOWN, HOLD, SMOOTH, MIN/MAX DISPLAY,
MIN/MAX
RESET, REF DISPLAY, or REF SET.
Selects or deselects resistance measurement.
Measures resistance within 2 k,
20 k, 200 k, 2 M,
and
20 M n ranges. At full scale, 2 V appears across
the test leads, which will bias a silicon semiconductor
junction
to forward conduction.
Measures resistance within
200, 2 k, 20 k, 200 k,
and 2 M n ranges. At full scale, 0.2 V appears
across the test leads, which will not bias a silicon
semiconductor junction
to forward conduction.
