I.Important
1. If the instrument is not in use, please turn off the power in time!
2. The rechargeable battery, as consumable part, ought to be well maintained. The effective capacity of rechargeable battery will fall gradually with time passing when the instrument is in use, which shortens the effective time of use. In order to prolong the service life of battery as long as possible, please pay attention to the following maintenance measures:
2.1 When the instrument is out of service for a long period, please charge and discharge the battery regularly at least once each month. Please use the compatible charger provided by our company to charge the battery so as not to damage the battery.
2.2 Insufficient-voltage use is strictly prohibited. The over discharge of the battery power will seriously shorten its life, and even make the battery scrapped; when the instrument prompts that power is low, you should stop using it as soon as possible and charge the battery to avoid battery failure due to excessive discharge of power.
2.3 Charging indicator: During charging,the indicator is red, and after charging, it is green.
2.4 When charging, the charger should be inserted into the AC220V power supply, and then the charging output plug will be inserted into the instrument for charging. Otherwise, the charger may not work properly.
3. Before using, the instrument must be Reliable grounded.
4. Correct wiring according to different testing methods.
5. When using wireless test mode, the instrument host and voltage collector must use the same wireless communication channel, otherwise, it will be impossible for wireless communication.
6. When using the wireless test mode, voltage collector must correctly install the antenna, otherwise, it is easy to burn the collector voltage wireless communication module; the instrument host must also correctly install the antenna,or it will greatly shorten the distance of wireless communication.
7. When using the wireless test mode, the distance between the host and the voltage collector should be more than 1 meter. Otherwise, the wireless signal of the instrument host can be saturated due to the over-strength of the wireless signal, thus the instrument host will be unable to receive the radio signal sent by the voltage collector.
II.Overview
Zinc Oxide Arrester Comprehensive Tester is used to check the electrical performances of the zinc oxide arrester (MOA).The instrument is suitable for on-site inspection of zinc oxide arrester at all voltage levels, as well as the factory test and acceptance test in the library when power is failed.By measuring the full current and resistive current and other parameters,it can be found that it is possible to detect the dangerous defects such as the internal insulation of the zinc oxide arrester and the aging of the valve.
