Function
POWER OFF/ON switch
Push on/push off switch that when
1
pushed to the in position applies ac
power to the voltmeter.
SAMPLE RATE control
Varies the sample rate from approxi-
2
mately 1 reading every 5 seconds
(CW) to about 20 readings/second
(CCW).
When
rotated
fully
counter-clockwise to the HOLD
position, the last sample measure-
ment is displayed until reset.
RESET/DISPLAY TEST switch
Momentary switch that initiates one
3
sample reading each time it is de-
pressed if the SAMPLE RATE control
is in the HOLD position. If held in
the depressed position, the status of
the display is checked by displaying
+1.88888.
Activates the ratio mode when
the
4
RATIO DC/DC, AC/DC, AC/AC
DC/DC switch is pushed in.
switches
The
A C / D C and AC/AC positions
are
used only when the appropriate
op-
tions are installed.
Selects ohms function (optional).
4a
Selects the mode of voltage mea-
5
VOLTS DC, AC, AC+DC
switches
surement; dc voltage (DC), ac rms
voltage (AC) or ac and dc compo-
nents combined (AC+DC).
SLOW RESPONSE switch
Push/push switch that when pushed
6
to the in position the lowest speci-
fied AC Voltage frequency input is
0.5 Hz.
FILTER LP/10 kHz switch
Push/push switch that when pushed
7
t o the in position attenuates AC
Voltage input frequencies above 10
kHz (-3dB at 10 kHz). Also selects
additional normal mode filtering in
DC Voltage and Ratio modes.
