Active Loads
LPAL L
7.6.21
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
3. Set the DAC count to 20% of its full range
4. Wait for the DC current to stabilize. After the current reading is
5. Set the DAC count to 80% of its full range
6. Wait for the DC current to stabilize. After the current reading is
