The Triplett MG530 Digital Insulation Resistance Tester and True-RMS Handheld Digital Multimeter is a versatile instruments that offers a wide range of functions. This tool can test insulation resistance up to 4000 megaohms using four test voltages of 125, 250, 500, and 1000 volts. Additionally, this tool can measure AC/DC voltage, resistance, frequency, and continuity. This tester comes equipped with a Lock Power function for hands-free operation which allows the user to focus on their measurements. This tool also features a live circuit voltage indicator for added safety. With a Flexible Clamp Current Sensor (not included), the MG530 is capable of measuring AC current up to 3000 amps.

For enhanced functionality, the MG530 offers a LoZ (impedance) mode to identify ghost voltages and a LPF (low pass filter) mode for filtering frequency and harmonic interference when measuring variable frequency drives. The backlit 4000 count LCD display with bargraph provides clear and easy-to-read results. Safety is a priority with the CAT IV 600V safety rating.
