Notes

1. Before testing, it is necessary to disconnect all power sources of the tested equipment and wait for the capacitor to fully discharge before measuring. Do not touch the metal end of the test probe during the testing process to avoid the risk of electric shock caused by the 500V test voltage. 2. Do not use the instrument in damp or rainy environments. Avoid prolonged use in areas with strong electromagnetic interference and high temperature exposure to prevent affecting measurement accuracy and instrument lifespan. 3. When not in use for a long time, please remove the internal battery to prevent leakage and corrosion of the main unit. Avoid excessive bending and pulling of the test leads, and store them gently to prevent internal circuit breakage from affecting normal testing. 4. Please allow a slight color difference caused by the shooting light and a 1- 3 cm error due to manual measurement, and make sure you do not mind before ordering. 
Key Features
 
Efficient Testing: This product outputs a 500V DC test voltage, covering a measurement range of 0-1000 megaohms. It is equipped with a soft load capacitor, which can automatically release residual voltage after testing, effectively improving safety.
 
Intuitive Judgment: It uses intuitive LED indicator lights to display zones, dividing them into three sections: poor, warning, and good. Without complex readings, maintenance personnel can easily identify equipment insulation aging and leakage hazards at a glance, and even beginners can quickly get started.
 
Easy to Carry: With a compact body and a matching portable storage bag, it is convenient for you to carry it to construction sites, computer rooms, HVAC maintenance sites, and carry out testing work at will.
 
Multi-scenario Use: This product is designed specifically for air conditioning compressors, fan motors, water pump motors, and cable circuits. It is commonly used for HVAC refrigeration maintenance, electrical troubleshooting, detecting winding-to-ground insulation faults, and effectively identifying coil moisture, damage, and aging faults.
 
Complete Set: This set includes an M500 insulated megohmmeter host, red and black crocodile clip test leads, a portable storage bag, and an instruction manual. The accessories are complete and do not require additional purchase. The storage bag can properly store the entire machine and wires to prevent collision and damage.
