Faulty probe. 888.8 appears in the
corresponding channel instead of a
temperature, meaning that the probe
is broken or disconnected.
Check the probe. The attached Pt
probes can be controlled using a
polimeter. Their temperatures can be
compared with the resistance values
stated in the following table.
Faulty probe. -88.8 appears in the
corresponding channel instead of a
temperature, meaning that the probe
is short circuited.
Check the probe. The attached Pt
probes can be controlled using a
