voltage and current of the scale under test (refer to Table 2-5).
OUTPut:RANGe 16V (command 1)
APPLy 16,10.5 (command 2)
OUTPut:STATe ON (command 3)
2)
Make sure that the power supply is in CV mode. Read and record the
current reading (U
3
) of the multimeter.
3)
Send the MEASure:VOLTage? command via the remote interface (USB, LAN
or GPIB). Read and record the retuned voltage (U
4
).
4)
Calculate the programming accuracy: |U
3
-rated output voltage of the scale
under test|;
Calculate the readback accuracy: |U
4
-rated output voltage of the scale
under test|.
5.
Press 32V/5A at the front panel and repeat steps 1 to 4 to test the
programming and readback accuracy at 32V/5A scale. The commands in step 3
and step 4 need to be replaced by the following commands respectively.
OUTPut:RANGe 32V
APPLy 0,5.25
OUTPut:STATe ON
and
OUTPut:RANGe 32V
APPLy 32,5.25
OUTPut:STATe ON
