9 USER DIAGNOSTICS
This section is intended to aid the user in solving common problems that may occur while using the UPC.
9.1
PROBLEM
Incorrect or illogical operation,
or: program values invalid,
or: "NO PROGRAM RUNNING",
or: "FPERR" is displayed.
PROBABLE CAUSE:
UPC memory has become corrupt.
NOTE: “NO PROGRAM RUNNING” may be a valid
message if the UPC was powered on while holding the fn
key. That will bring up the SETUP MENU directly, without
any Program executing and therefore no output. If CLEAR
is pressed, the UPC will indicate “NO PROGRAM
RUNNING”. Select a PROGRAM and EXECUTE to initiate
normal operation and display the V/I screen
SUGGESTED CURE:
Clear ALL RAM and RESET CPU (4.6.1.3).
To prevent the UPC from executing a program upon power-
up, press the fn key while applying power with the INPUT
POWER switch, then press fn again to enter SETUP mode.
If after Reset, the unit functions properly but the problem
recurs after being powered-down, the battery that maintains
the RAM data probably needs to be replaced.
9.2
PROBLEM
LCD Display not readable
PROBABLE CAUSE:
LCD view angle is not adjusted correctly,
or
UPC memory has become corrupt.
SUGGESTED CURE:
Access the LCD setup screen (fn3,2),
or
Clear ALL RAM and RESET CPU (4.6.1.3).
