Product Details

micro-ohm meter portable loop resistance meter contact resistance tester

Product Description

Important Note

If the instrument is not in use, please turn off the power in time.

If the instrument is not used for a long time, please charge and discharge regularly. Batteries should be charged and discharged at least once a month.

It is strictly forbidden to use power shortage, which will severely shorten the battery life and even make the battery scrap. When the instrument is short of power, the power supply should be switched off and charged immediately. Avoid battery failure due to excessive battery discharge time.

Charging lamp: the charging lamp on the charger is bright red during charging and bright green after charging.

Users must not disassemble the instrument and replace the battery without authorization. When the instrument or battery fails, please return to the factory.
