Averager‘off’responsetime: 2ms(10to90%)
Averageradjustmentrange: 175msto4s(10to90%)(typical)
Peakpickeradjustmentrange: 5000%to1%span/s(typical)
Peak picker response time*: Set by averager response time
Peak picker remote reset characteristics: Activated by a contact closure
(mustbeaoatingandisolated
contact).Contactmustbeclosed
for 20ms to reset the peak picker.
Powersupply**: 24Vto30Va.c.(50to60Hz)/30V
to 45V d.c. at 200mA. The supply
must be isolated, fused and short
