7. Press ENTER to start calibrating. Calibration takes about 20 seconds so
remember to maintain constant pressure on the adapter’s terminals
until the test is fully completed.
8. Remove the adapter when prompted.
Adapter Calibration Values
Adapters are calibrated at the factory and the calibration value is permanently
stored in adapter memory. After calibration, the new calibration value and factory
calibration value are compared.
- If the difference between the calibration values is less than 50mΩ, the new
value is displayed on the screen and replaces the factory calibration value.
- If the difference is more than 50mΩ, the calibration value and the original
factory calibration value is displayed; select Yes or No to accept or discard
the new value.
- If the new calibration is over 400mΩ, the new value is rejected.
Acceptable Calibration Values for New Adapters
General calibration values are provided below to help gauge whether a calibration has been
performed properly. If a brand new adapter is calibrated using appropriate tools and the
displayed resistance is greater than that shown below, repeat the calibration.
To check the analyzer version, press the keys Fn-7. If the adapter is consistently displaying
larger resistance values than in the list, please contact technical support (page 121).
