Environment  Please do not operate the instrument in the place that is dusty, vibrative, under direct sunlight or where there is corrosive air.  The normal working temperature is 0 ℃～ 40 ℃ , relative humidity ≤75%, so the instrument should be used under above condition to guarantee the accuracy.  Please store the instrument in the place where temperature is between 5 ℃ and 40 ℃ , humidity is less than 85%RH. If the instrument will not be put in use for a time, please have it properly packed with its original box or a similar box for storing.  The instrument, especially the test cable should be far from strong electro-magnetic field, to avoid the jamming on measurement.

Use of Test Fixture Please use the accessory test fixture or cable together with your device. The test fixture made by user or from other company may cause the incorrect measurement result. The test fixture, cable and the pin of DUT should be kept clean, thus to guarantee the good connection between DUT and fixture. Warm-up  To guarantee the accurate measurement, the warm-up time is no less than 15min.  Please not turn on or off instrument frequently, in order to avoid the inner data fluster. General Check When you have got a new LCR, it is suggested that you should perform a general inspection on the instrument according to the following steps:  Check the shipping container for damage:

Inspect the shipping container for damage after unpacking it. It is not recommended to power on the instrument in the case of a damaged container.  Check the accessories: Accessories supplied with the instrument are listed in ― Accessories ‖ in this manual.
