Performance Tests
Performance tests are recommended for incoming inspection, periodic maintenance, and
for checking the thermometer’s specifications. If the thermometer fails any part of the
performance tests, calibration and/or repair is indicated.
Before performing these tests:
1. Allow the thermometer to stabilize to room temperature, +23
o
C ± 5
