Technical data
[93]
• First meter of EZ 108x at temperature of EZ 108x.
• No ambient temperature change of EZ 1000 during 1 hour before measurement,
power and sensor connected to EZ 1000 for at least 10 minutes before
measurement and calibration.
• WayCon reference target material is 42CrMo4 (AISI 4140), unless otherwise stated.
Note
For measurements that require a higher measuring accuracy, factory calibrated measuring chains are
available.
Calibration methods Offline (Easy) and Automatic – typical values
The values of
Table 11-3
are typical values for measuring chains, calibrated with calibration
method Offline (Easy) or Automatic.
Accuracy of non-API 670 conform measuring chains
Add the measurement inaccuracies in
Table 11-4
to the values in
Table 11-3
to get the
accuracy of non-API 670 conform measuring chains.
