Test Notices
For optimum performance, all procedures should comply with the following
recommendations.
1) Make sure the environment temperature is stable and between 18℃ and 28℃.
Ideally, the calibration should be performed at 23℃±1℃.
2) Make sure the environment relative humidity is less than 80%.
3) Make sure that the instrument has been warmed up for at least 30 minutes
before the calibration.
4) Keep the test cables as short as possible and make sure that the impedance of
the cable is consistent with the requirement.
