Q: I have configured my load and turned on the input, but nothing seems to be sinking. The current
shows 0.00 A as if nothing is happening.
A: There are 2 conditional parameters in the SYSTEM SET menu that is used for specific test
applications. These parameters can affect the control of the input depending on the applicable
conditions. To disable or operate the load under normal conditions, press Shift + 0 to access
the menu system. Go to SYSTEM SET, and press Enter. Scroll until you see VOLTAGE ON SET
and VOLTAGE OFF SET. Press Enter into each of them and set both parameters to 0.00 V. Be
sure to press Enter again after changing the value so that the changes get saved.
Q: I changed some parameter settings, but my changes don't seem to apply.
A: Every time a menu option or parameter is changed, you must press Enter to save those
changes before exiting the menu. Exiting the menu without doing this will void any changes
made.
Q: How do I get the load to display more resolution from the PV8500 software?
A: When the PV8500 is starting communication, it sets all parameters to some default values.
This includes setting the range to default (10 mV, 1 mA resolution). To operate the PV8500
software in low range where an extra digit of resolution can be used, first initialize and run the
PV8500. Once the load is connected to the software and communicating, use the software
switch at the bottom to change from PC Control to Panel Control. While the load is remained
connected, front panel operation is enabled at this point. Press Shift + 0 to go into the Menu
system, and go into Config menu. Select RANGE SELECT and set it to ON. Press Enter to save.
Now, exit the menu system by pressing Esc a few times. Press Shift + Up arrow to enable 1 mV
resolution, and Shift + Down arrow to enable 0.1 mA resolution. Once set, go back to the
PV8500 GUI soft panel and change the switch from Panel Control to PC control.
