Test Conditions
For the optimum performance, all the procedures should comply with the following
recommendations.
1. Provide proper working voltage for the device.
2. Make sure the environment temperature is stable and between 18℃ and 28℃.
Ideally, the calibration should be performed at 23℃±2℃.
3. Make sure the environment relative humidity is lower than 80%.
4. Make sure that the instrument has been warmed up for more than 1 hour before
the test or calibration.
