Measurement Accuracy

Thermocouple sensors have small errors in their response over frequency. The
response of each sensor is measured during manufacture to determine correction
factors. With the U8480 Series thermocouple sensors, correction factors are
stored in a 3 MB Flash memory and are downloaded to the power meter
automatically.
Using calibration factors enables improved measurement accuracy. This section
describes making average power measurements using the U8480 Series
thermocouple sensors.
Making a measurement requires the following steps:
1 Zero the power meter/power sensor combination.
2 Set the frequency for the signal you want to measure.
3 Make the measurement.
Procedure
1 Zero the power meter/thermocouple sensor combination.
2 Ensure the power sensor is disconnected from any signal source.
