‘Check Probe’ Error Message
This message typically indicates an error generated by the
probe tip being wet. Dry the tip and cycle the device power
off then back on. If drying the tip of the probe does not
resolve the error, then the probe may have degraded to the
point that it will require replacement.

connector and gently push in until properly seated.
