Accuracy
Set values voltage / current
≤1% of the nominal value *
Actual values voltage / current
≤1% of the nominal value *
* Note:
The minimum accuracy or the maximum error is the difference between the desired value (set value) and the true value (actual value) on the
output. This is error comes from the sum of tolerances of any component that is involved in the output value generation or actual value measuring.
The error is always present and can result in offsets of voltage or current on the output, even if current = 0A was set while the voltage is not zero,
or even if voltage was set to 0V. It means, the device might supply small voltage and current with these set values. This offset can not be compen-
sated. In such a situation it is required to switch the DC output off in order to make the device not supply power anymore.
For other values it might be required to measure empiric data along the whole range of voltage and current in order to get an overview of the error,
which is not constant over the whole range. The data could then be used to add certain values to or subtract from the desired set values, in order
to bring the actual values as close as possible to the set values.
