The default setting is for a K-type thermocouple
(input type = 5). If a different sensor is used, an
input error (s.err) will occur. Check the setting of
the Input Type parameter.

Note Wire all voltage input terminals correctly. The Digital Controller may
fail if the voltage input terminals are wired incorrectly.
Control outputs that are voltage outputs are not isolated from the internal circuits.
When using a grounded thermocouple, do not connect any of the control output ter-
minals to ground. (If both are grounded, measurements will be unreliable due to
sneak current.)
