fixed step gain factor.
AMPLIFIER (VAR. ): operates in conjunction
with VAR.GAIN to provide variable control of
amplifier gain anywhere between zero and Xl O .
SU P PLY: selects full scale ranges of ±l, ±2,
±4, ±lO, or ±20 volts.
VAR GAIN/ VOLTS ADJ.: operates in conjunc­
tion with AMPLIFIER/ SU P PLY control to pro­
