Operating manual
•
Operating the TP281300
2-wire circuited resistance thermometers measuring an
actual temperature.
Connect the resistance thermometer as shown below:
5.2.1 Testing temperature switch
Caution:
Burning heat: Let the TP281300 cool down after use
(see paragraph „Cool down heating block“).
Note:
To obtain an exact measuring result the specimen has to
fit properly in the bore of the heating block or of the
transition casing.
Prerequisites for exact results:
• The outer diameter of the test piece
matches the inner diameter of the
bore hole
(--->Sect. 3.4.1 "Transition casings").
• The calibrating instrument is in
vertical position.
• Unbended specimen.
• Insert the specimen in dry state
directly into the bore of the heating
block or in that one of the appropriate
transition casing.
• The measuring element of the sensor
is located in the region of the
homogeneous zone* of the calibrator
heating block.
Note:
Before starting the measurement the specimen must have
obtained the temperature of the block.
Give the specimen enough time for coming up to the block
temperature level.
