CHECKING
Check thermostat in removed condition.
- Measure dimension „a“ on the thermostat.
NOTE: „a“ = stroke beginning at approx. 83 ± 2°C (T1)
„b“ = stroke ending at approx. 95°C (T2)
- Heat up thermostat in the water bath.
For a determination of the exact opening point, the
temperature reading should take place as closely as
possible to the thermostat, however, without contacting
the latter.
The water must be continuously stirred to arrive at a
uniform distribution of temperature. The rate of rise of
temperature should not exceed 1°C/ min. at a maximum
otherwise opening will be delayed correspondingly.
- Measure dimension „b“ on the thermostat.
Stroke length at indicated temperature (T2) 8 mm at
aminimum.
