FUNCTION SELECTOR: This control is used for
selecting type of measurement to be made. They
are: ±DC Voltage, ±DC Current, AC Voltage,
and resistance measurements.
AC ZERO: This control provides adjustment for
zero-setting the meter before making AC volt-
age measurements.
MECHANICAL ZERO ADJUST: This adjustment
mechanically zero-sets the meter prior to turn-
ing on Voltmeter.
RANGE:
This control selects the full scale
meter range.
AC POWER SWITCH: This push button - lamp
combination, when depressed, turns the instru-
ment power on or off. The push button glows
when the Voltmeter power is on,
DCA-OHMS: This lead is used in conjunction
with the COM Lead to measure DC current or
ohms. The FUNCTION SELECTOR determines
which measurement is made.
COM: This lead is used with the input leads for
DC voltage current, AC voltage, and resistance
measurements. The COM Lead is normally
floating; however, a shorting bar can be con-
nected from the floating ground terminal to the
chassis ground terminal on the DC AMPLIFIER
OUTPUT connector. If a shorting bar is not
used, the COM Lead is floating except when the
FUNCTION SELECTOR is set to ACV.

DCV: This lead is used in conjunction with the
COM Lead to measure ±DC voltage.
AC PROBE (300V MAX): Receptacle for tele-
phone-type plug of Model 11036A
AC Probe.
With probe connected the Voltmeter may be
used to make AC voltage measurements.
ADJUST: This control is used to set meter
pointer to before resistance measurements
are made. Only periodic adjustment
of
this
screwdriver adjustment is necessary.
LINE VOLTAGE: This two-position slide switch
sets the instrument to accept either 115 or 230
volt AC primary power.
FUSEHOLDER: The fuseholder contains a 0. 25
ampere slow-blow fuse for both 115 vac and
230 vac modes of operation.
AC POW ERCONNECTOR: Accepts power cable
supplied with the instrument.
DC AMPLIFIER OUTPUT: Provides DC vol-
tage output proportional to meter indication for
driving external recorder. 1.5 volts DC out-
put for full scale meter deflection.
