3 Using the PVA-600
3-3
Setting Up the PVA-600
1.
Place the I-V Measurement Unit close to the PV device to be measured.
NOTE
The PVA-600 will automatically shut down if its internal temperature reaches a preset
limit. Internal temperature is increased by PV energy collected during I-V sweeps, and
also by heat absorbed from the environment, including high ambient air temperature, hot
surfaces on which the PVA-600 is placed, and exposure to direct sunlight.
CAUTION
Place the PVA-600 in the shade to reduce the likelihood of
thermal shutdown. Never
place the PVA-600 on an asphalt driveway or on a roof in direct sunlight.
2.
Ensure that the connector-saver jumpers are installed on the primary test leads.
3.
If necessary, connect alligator clip leads or extension cables to the connector-saver
jumpers. Use only clip leads or cables that are rated for at least the maximum current
and voltage of the I-V Measurement Unit.
4.
If long extension cables are connected to the I-V Measurement Unit to reach the test
device, the cables should be laid alongside one another rather than in a loop, to
minimize the inductance they add to the measurement circuit.
5.
Connect the Wireless USB Adapter to a USB port in your computer.
6.
If you will be using the PVA Sensor Kit, refer to Setting Up the Optional PVA
Sensor Kit for setup information.
