Figure 2-46 LED Test Function
The parameters for the LED test mode include Range, Io, Vo, Rco.
Set Range
Current range: 5 A or 30 A
Voltage range: 36 V or 150 V
Set Vo
The working voltage at the operating point.
Set Io
The working current at the operating point.
Set Rco
Set Rd by the following formula:
3.
Turn on the input channel
Press On/Off to turn on the channel input. At this time, the actual sink
voltage, current, power, resistance will be displayed on the main
interface. The sink current will be increasing with increase input voltage
of the load.
Note:
Once the channel input is turned on, the load will not start to sink the
current until the input voltage is greater than the break-over voltage.
