Iset / Imon Resolution

:
If IMON RANGE = High is selected resolution is 5 nA
If IMON RANGE = Low is selected resolution is 0.5 nA
0 ÷ 5600 V
Absolute maximum HV level that the channel is allowed to reach, independently from the preset value
Vset. Output voltage cannot exceed the preset value Vmax. The accuracy is 1 % ± 5 V
Open collector, 100 mA maximum sink current
LOW: <1V; current~5mA; HIGH: 4÷6 V
1÷500 Volt/s, 1 Volt/s step
Max. time an "overcurrent" is allowed to last (seconds). A channel in "overcurrent" works as a current
generator; output voltage varies in order to keep the output current lower than the programmed
value. "Overcurrent" lasting more than set value (1 to 9999) cause s the channel to "trip". Output
voltage will drop to zero either at the Ramp-down rate or at the fastest available rate, depending on
Power Down setting; in both cases the channel is put in the OFF state. If trip= INFINITE, "overcurrent"
lasts indefinitely.
TRIP range: 0 ÷ 999.9 s; 1000 s = Infinite. Step = 0.1 s
