Measurement Accuracy
The absolute measurement accuracy is based on the internal
measurement electronics, the reference temperature sensors, and
the thermocouples.
Note:
If an absolute temperature value and a percentage value
are specified for a measurement error, the larger measurement
error or the largest error deviation regarding to the
measurement result applies.
4.1
Measurement Errors due to Measurement
Electronics
Due to the internal circuitry and equipment of the device, a
maximum deviation of
1 K
or
0.2 %
of the measured value may
occur.
4.2
Measurement Errors due to Reference
Temperature Sensors
The measurement of the thermocouples results in a differential
temperature between the measuring point and the temperature of
the measuring socket. This differential temperature can only be
converted into an absolute temperature based on the reference
temperature sensors.
The temperature sensor has an error of typically
0.5 K
and,
depending on the ambient temperature, a maximum of:
±1 K
at ambient temperature from 0 to 70 °C
±2 K
at ambient temperature from -20 to 85 °C
