(62) dBV/dBm Selects or cancels dBV or dBm.
dBV
Displays ac rms voltage measurements as the log of
the ratio of the input voltage to 1 V. Readings equal
20xlog(V
jnput
/V
ref
), where V
jnput
is the input voltage
and V
ref
is 1 V. With zero input, the readout
displays "OVER."
dBm
63) CONT
Displays ac rms voltage measurements as the log of
the ratio of the input voltage to a 1 mW reference at
600 ft. Readings equal 20xlog(V
jnpu1
/V
ref
), where
v
m
P
ut
is the in
P
ut
voltage and V
ref
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 ft, the instrument produces an
audible tone. The readout shows either "SHORT <
10 ft" or "OPEN > 10 ft." 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.
(64) HI ft/LO ft Selects or deselects resistance measurement.
HI ft
Measures resistance within 2 k, 20 k, 200 k, 2 M,
and 20 Mft ranges. At full scale, 2 V appears across
the test leads, which will bias a silicon semiconductor
junction to forward conduction.
LOft
65) °C/°F
Measures resistance within 200, 2 k, 20 k, 200 k,
and 2 Mft ranges. At full scale, 0.2 V appears across
the test leads, which will not bias a silicon
semiconductor junction to forward conduction.
Selects or deselects temperature measurement. If a
temperature probe is not connected to the input jacks,
the readout shows "ATTACH TEMP PROBE/'
Measures temperature in Celsius degrees.
Measures temperature in Fahrenheit degrees.
