In-line Calibrated Dials.- Two dials set the output voltage in 200 and ZO-volt steps. Trim Control permits interpolation between ZO-volt setting, with 100 millivolt resolution. b. Overload Protection.- Repeated or continuous overloads will not damage the instr,m,ent. Protection circuit limits the oucput current to less than 13 milliamperes with automatic recovery when overload is removed. c. Stability.- Solid-state design, stable range resistors, and selected zener diode provide voltage stability of +0.005% for B-hour periods after onehour warm-up. d.
