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.
