Voltage output (AO-U) mode
Output response to On/Off switching operations of power supply
Without supply voltage
High-impedance output:
A+ to AGND > 300 k
Ω
A- to AGND > 300 k
Ω
A+ to A- > 300 k
Ω
During booting routine
of the DC1000
The analog output is not yet active during the booting routine of the DC1000.
Differences to zero value when switched on and off is around < 2 %.
If there are brief inter-
ruptions
If the supply voltage > 100 µs, the AO are briefly switched to high impedance.
Behaviour in STOP
mode
Voltage output 0 V
Usage of the AI
during AO operation
The current that really flows can be indicated if the analog input is configured
as
AI-I
.
The voltage between A+ and A- can be displayed if the analog input is confi-
gured as
AI-U.
Readjustment is not required because it is readjusted internally.
