Raynger 3i Series Operator’s Manual C-1
APPENDIX C: TROUBLESHOOTING
The portable instrument is equipped with a failsafe program that lets you know if it is
over or under range while in the MAX, MIN, DIF, or AVG modes. The failsafe pro-
gram also lets you know the instrument has a failed component. All failsafe informa-
tion displays on the control panel and is sent to the RS-232 and analog outputs.
Figure C-1 shows how the control panel displays the over range and under range fail-
safe codes.
MAX Mode: If the object’s temperature is over range, the panel’s main and mode dis-
plays and RS-232 output are sent the -O- failsafe code. The analog out-
put is sent the maximum temperture for your model.
If the object’s temperature is under range, the panel’s main display and
RS-232 output are sent the -U- failsafe code. The mode display and RS-
232 ouput are sent either the correct MAX temperature or the -U- failsafe
code. The analog output is sent the minimum temperature for your
model.
