Voltage output AO (U)

Description
1
Terminal block
▶
Connect the voltage outputs directly to the input channel AGND.
If direct connection to the AGND is not possible: connect the voltage input to the overall GND of the device.
▶
AGNDs which are also used by other input channels should not be connected to the same terminal block in
order to avoid changes in the voltage to the AO (U) and the temperature value.
▶
Only use the corresponding AGND for each power input.
▶
Ensure that the cable resistance is substantially lower than the load resistance R
L
so as to guarantee high
measuring accuracy. Take into account the voltage divider between the load and cable resistance.
