Safety Precautions
Pre-test Preparation
Power off the tested equipment completely and discharge it fully; wipe off oxide on the terminals and fasten the test leads firmly.
Gear Operation
Select the current gear according to the type/impedance of the test object, no over-range testing; manual gear selection is recommended for high-precision measurement.
After Testing Inductive Objects
Do not disconnect the test leads immediately after testing; operate only after the instrument prompts the completion of residual voltage release.
Power Supply & Environment
Connect to 220V compliant mains power, avoid unstable power supply; do not use for a long time in harsh environments with excessive dust, high humidity or strong electromagnetic interference.
Printing & Data Management
Load printing paper properly before printing to prevent paper jams; print and file historical test data in time to avoid data loss.
Maintenance & Storage
Tidy up the test leads after use; store the instrument in a dry, ventilated and non-corrosive environment, check the terminals regularly, and disconnect all external lines when the instrument is idle.
