1-2. FEATURES.
a. 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. Model 2441 Overload Protection Option.- A,,
optional protection circuit is available (on special
order) which can be used to limit the current of the
Model 244 when monitored by e Keithley picoammeter
such es the Model 414A.
