The MT565 is a Bluetooth Insulation Tester and Multimeter. The MT565 measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle and temperature. The Low pass filter can accurately measure variable frequency drive (VFD) signals. The insulation tester offers 50V, 100V, 250V, 500V, and 1000V ranges with an insulation resistance up to 5000MΩ, DAR and Auto PI functions with adjustable time setting and an auto discharge. The Low Ohm function offers a resolution of 1mA and an open circuit voltage of 5V. The meter has a 50 000 count LCD dual display with an analogue bar graph, and the CAT IV 600V rating ensures the highest level of safety. The unit offers Bluetooth communication and an internal memory to store and transfer information. The Bluetooth app is available on both Android and iOS platforms. This provides maximum versatility and a wide range of features for both trouble shooting and preventative maintenance electricians.
