介电常数高频测试仪维修

1．新购仪器的检查

新购的仪器能先用LKI-1电感组，将各个电感在各个不同频率测试Q值，把测试的情况，例使用的电感号、测试频率Q读数、电容读数等多次测得数及测试环境条件逐一详细记录，并把记录保存起来，以供以后维修时作参考。

LKI-1电感组是测试时作辅助电感用的，不能把这些电感当作高精度的标准电感看待。随着测试环境条件不同，测得电感器Q值和分布电容可能略有不同。

2．使用和保养

高频Q表是比较精密的阻抗测量仪器，在合理使用和注意保养情况下，才能保证长期稳定和较高的测试精度。

a．熟悉本说明书，正确地使用仪器；

b．使仪器经常保持清洁、干燥；

c．本仪器保用期为18个月，如发现机械故障或失去准确度，可以原封送回本厂，免费修理。
