3 Software Overview
3-14
Name Description
Set I-V Curve
Resolution... Displays controls for selecting the number of measurement points in
your I-V curve. Select 100 points for commissioning and most
troubleshooting. Select 500 points for some research and more
detailed troubleshooting applications. The resolution can be changed
at any time, and will remain in effect for subsequent measurements,
until you change it again.
The software responds much more quickly when using 100 points.
Ports... This menu item appears only in the software for the PVA-1000S and
PVA-600+, where the control is used to identify the COM port into
which the wireless USB adapter is plugged.
Battery Level…
To check the battery voltage, select Battery Lev
el…
in the Utility
menu, or just click on the Status indicator any time the indicator is
displaying
Ready . Battery voltages are also listed in many of the
popup messages that accompany status and disable messages. The
battery voltage at which the unit will shut down is also reported. Wait
30 seconds to check the battery voltage if you just removed the I-V
unit from the charger or just turned on the I-V Unit. This allows
internal functions to complete, for a more accurate battery reading.
In the PVA-1500xx software, the battery levels of both the I-V
Measurement Unit and SolSensor 300 are reported. In the PVA-
1000S and PVA-600+ software, only the I-V Unit voltage is reported.
The instruments shut down when the battery voltage has dropped to
a preset lower limit. A warning appears in the software approximately
one hour before the shutdown.
The shutdown voltage levels are:
PVA-1500xx I-V Measurement Unit and SolSensor 300: 3.05V
PVA-1000S, PVA-600+, and original SolSensor: 2.9V
The type of Lithium ion battery used in these instruments has a very
square discharge curve, so there is relatively slight variation in
battery voltage from the fully charged state to the shutdown level.
