changed states. This feature allows for minimal block temperature scanning
times and improved accuracy.
Example 2:

troller automatically sets a new set-point of 50°C and the status flashes either
"o or c".
Note: There is a delay between the displayed temperature and the actual tem
-
perature of the thermal switch. To achieve better accuracy when the thermal
switch is tripped, the scan rate should be set for a slower time. The slower the
scan rate the more time required to perform a test. The operator must determine
the optimal scan rate for the specific application.
