Calibration Run (CalRun)
The first test sets the dry block to the required temperature. CalRun displays the readings
from the internal dry block reference or external reference probe as the temperature reaches
the set point. Once the temperature is stable and is within the setting band, the reference
temperature is recorded.
The example above shows a reference test using an external probe. The value shown in the
main reading display (25.080°C) is the value of the reference probe measured by the DMM.
Although it states ‘U.U.T reading (°C)’ the measurement is the reference probe. The setting
band is ±0.5°C. The dry block temperature (25.120°C) is shown in the auxiliary reading
display. Time to stability (5 minutes) is also shown in this section.
Note:
When using an external reference probe the setting band for the dry block calibrator is set to ten times the
value of the reference probe setting band. This allows the external reference probe to control the accuracy of the
set point.
