Test the pen and how to install it when you use it. Note: This meter is a high voltage tester. Check whether the gauge is in good condition before use. It cannot be used if it is damaged. During measurement, a high voltage is applied by the test lead. Do not touch the bare wire or the metal part of the test lead directly with your hands to avoid electric shock.

The SM-852B phase tester has two main functions, open phase and phase sequence detection and display. Test lead: red corresponds to the U (R) phase (L1, R); yellow corresponds to the V (Y) phase (L2, S); green corresponds to phase W (B) (L3, T). 3 test props, pins can be connected with crocodile clips
