Raynger 3i Series Operator’s Manual C-3
FAILED COMPONENT
If the microprocessor fails, the panel’s main and mode displays and RS-232 output are
sent a 7777 failsafe code (see Figure C-2). The analog output is sent the maximum
temperature for your model.
NOISY OR RANDOM READINGS OR SYSTEM LOCKUP
Noisy or random readings or a system lockup may be caused by electromagnetic
interference from nearby unshielded equipment. To clear the instrument’s system,
release then press the trigger. If this does not clear the problem, slide the battery door
off then back on. (This disconnects the battery power.)
