Resolution for Symptom 2
Execute the suggested procedure to resolve symptom 1 first. If an occasional error continues
to occur while slewing the voltage or frequency slider controls in the PGUI program, add a
command delay to the PGUI ini file using the following procedure. This symptom may occur on
some PC’s.
Procedure
1. Close the PGUI program if it is still open.
2. Use the Windows Explorer and select the PGUI directory or the directory into which you
installed the PGUI program.
3. Locate the PGUI.INI file (Type = Configuration Settings).
4. Open the PGUI.INI file using a text editor such as Notepad.
5. Locate the [Interface] section and find the entry called “CmdDelay”. If no such entry is
present add it yourself.
6. The default value for the CmdDelay is set to 0. Change this value to 10.
7. Your PGUI.INI file should look like this now:
[Interface]
Bus=0
CommPort=2
GPIBDriver=0
ACSourceAddress=1
CmdDelay=10
[PowerSource]
Model_number=0
[WindowState]
Top=5272
Left=6112
Height=4815
Width=6975
8. Save the file using the File, Save menu.
9. Close Notepad and start the PGUI.
10. Try to connect again. You may have to cycle the power on the AC source if it still shows
the Err -100 display.
Higher values than 10 may be set for the CmdDelay parameter if this fix does not resolve your
problem.
