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 PGUI32
program, add a command delay to the PGUI32 Registry Interface section using the following
procedure. This symptom may occur on some PC‟s.
Procedure
1. Close the PGUI32 program if it is still open.
2. Run the Windows Registry Editor (Regedit.exe) from the Run command line.
The correct setting is located at the following key:
HKEY_CURRENT_USER\Software\VB and VBA Program Settings\pgui32\Interface
3. Locate the HKEY_CURRENT_USER key and double click on it
4. Locate the Software key and double click on it.
5. Locate the VB and VBA Program Settings and double click on it.
6. Locate the Pgui32 key and double click on it.
7. Locate the Interface Key and double click on it.
8. In the right pane of the Registry Editor should be an entry called "CmdDelay". If no such
entry is present add it yourself.
9. The default value for the CmdDelay is set to 10. Change this value to 20 by double
clicking on the CmdDelay key and entering the new value from the keyboard.
10. Close the Registry Editor when done.
11. 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 20 may be set for the CmdDelay parameter if this fix does not resolve
your problem.
