ALIBRATION
This procedure calibrates the current for the low range. Make sure that the
shunt and the DC current meter are connected between the active load and
DC power supply.
This procedure requires maximum voltage 5.0 V and maximum current 0.5
Amps.
1. Set the DC input voltage to 5 Volts
2. Turn on the active load
INP:STATE 1
3. Set the DAC count to 20% of its full range
CAL:INP:CURR:COUNTS 16000
4. Wait for the DC current to stabilize. After the current reading is
stabilized, enter the current using following command
CAL:INP:CURR1
5. Set the DAC count to 80% of its full range
CAL:INP:CURR:COUNTS 53000
6. Wait for the DC current to stabilize. After the current reading is
stabilized, enter the current using following command
CAL:INP:CURR2
