I got some problem with my 5520A.
DC voltage is OK.
AC voltage is OK for this voltage:
- 100 V
- 200 V
- 380 V
- 400 V
- 500 V
- 600 V
- 700 V
and not OK for this:
- 220 V
- 250 V
- 300 V
- 700 V
- 800 V
- 900 V
- 1000 V
It is not possible to make ZERO, then give this errors:
- 1505 (DDE:FRS ) VDAC counts out of range
- 399 (QYE:F ) Fault during %s
- 104 (DDE:FR D) Hardware relay trip occurred
