Calibrator 5520A - hold current
I am writing my graduation work, now.
I have a Fluke calibrator 5520A and would like to control this over the software MET/CAL 8.2. The 5520A is to be used as a current source with 40mA. The second device is an reference mulitimeter 8508A, this should read the current automatically.
My question is:
How can the calibrator hold the current with 40mA, while the reference multimeter reads it?
The proceedure now is:
- calibrator give 40mA --- breaks off to offline
- reference multimeter --- error because the calitbrator is offline
