GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
OUTPUT ACCURACY
Meter reads true output voltage
within 3/l£ of full scale
OUTPUT FREQUENCY
Selection of either DC level or
1 KC square wave (positive going
from ground).
OUTPUT VOLTAGE
In 9 fixed steps from 0.01 volts to
100 volts full scale. VARIABLE control
permits continuous selection of any
voltage between 0.002 volts and 100
voltse
OUTPUT IMPEDANCE
1.06 ohms to approximately 2200 ohm
OUTPUT IS DIRECTLY METERED SO EXTERNAL
LOADING WILL МОТ CAUSE ERRONEOUS INDI-
CATION.
UNKNOWN INPUT
2mv to 100 volts may be applied for
comparison with internal calibrator
signal. The input impedance would be
equal to the input. Impedance of the
monitoring device connected to the
OUTPUT.
COMPARATOR
60 cycle mechanical chopper.
