EXHAUSTED PROBES
If the probes are not within the tolerance limits, reading will not get stable or show erratic
values. Should this occur, clean the probe, and try to recalibrate it.
During the calibration process, in case a probe is out of specifi cation, the controller will
prompt you
ERROR NR. ####
Any key to continue
If you have cleaned the probe twice and you are still having problems, you will
need to purchase an Elos replacement probe from the dealer where you purchased the
controller .

bes, 12 months for standard grade probes, or as needed for accuracy and reliability.
