Auto Mode: It has an ‘auto’ setting that allows it to automatically recognize what it's measuring and act accordingly, for the most common measurements, Volts AC or DC, resistance, or continuity. All you need to do in this smart mode is attach the probes, and it will work.
Multi-Function: The ST600 multimeter can measure max 600V AC/DC voltage, 10A AC/DC current, and 60M Ohms resistance, the tester also tests temperature, capacitance, frequency, and duty-cycle, wire on-off, diodes, and continuity.
Upgraded & Convenient: Replace the gear knob with 2 buttons, and use it as a smartphone. More convenient than a meter with only 1 function button, you can manually select the function to the left or right. The jack is on the front, so the multimeter can be placed upright.
Colored Indication (ST600Y only): With an LCD screen that is bright and clear. Different colors separate readings from functions and make the results easier to record. It has a red light at the back, an indicator light on the top, and 3 flashing lights on the port, easy to use.
