Product description
The MR CARTOOL circuit probe is an electrical tester to reduce diagnostic time in all 6-30V automotive electrical systems, can check for continuity, check for polarity, check for bad ground contacts, check switches, relays and the on-off of diodes, fuses and check circuits, trace and locate short circuits.
In diode mode you can check the forward voltage or reverse voltage.
In DC voltage mode, connect the probe tip to a circuit and the LCD display will show the DC voltage. The resolution is 0.1 V.
In AC voltage mode, connect the probe tip to a circuit, the LCD display shows the maximum/minimum voltage, frequency and duty cycle.
In resistance mode, connect the probe tip to a circuit, the LCD display will show the resistance between the tip and the auxiliary earth cable.

【Power Circuit Probe Tester Set】MR CARTOOL B530 circuit probe tester adopts advanced power board, which make it quite accurate. Main functions: voltage test, polarity test, continuity test, signal circuit test, components activate, grounding test, locate short circuit, circuit breaker protection, etc.
【4 Working Modes】4 working modes: DC Voltage, AC Voltage, Resistance test, diode test. DC Voltage mode can read DC voltage with 0.1V resolution; AC Voltage can read Max & Min voltage, frequency and duty cycle quickly; Resistance test mode can read resistance between tip and auxiliary ground wire.
【Overload Protection】This B530 electrical system probe tester has a built-in short circuit protection. When overloaded, the built-in internal short circuit will automatically trip to ensure the safety of users and prolong the service life. In order to protect your components, the car circuit tester can also do quick self-test.
【33ft Extension Cable & Built-in Flashlight】Circuit tester comes with an extra 33ft extension cord to reach further distance. With the built-in Flashlight, more convenient to test in dark environment.
【We can offer help】Please do not mix the positive and negative. CARTOOL car circuit tester provides 2-year warranty. Please contact us if you need any help.
