LIAMOS PB100 Automotive Circuit Tester Power Circuit Probe Kit Electrical System Diagnostic Tool Voltage Power Scanner,Wide Test Range

Using a probe tester, you can check voltage and ground signals in typical DC circuits. You can also use it to send voltage and ground signals. Components and circuits can be efficiently tested without taking apart old clips and jumper wires. You can power or ground the circuit directly through the top of the unit.Product Features:Resistance range: 0-100k;Rated current: 1-10 amps;Frequency response of sound channel: 0Hz to 10Khz.Perform current injection, measurements, ground testing, polarity testing, continuity testing and component activation.Ergonomic case design features a waterproof, rugged blow-molded case for easy handling and storage.There are 4 modes for diagnosing the electrical system. (DC voltage, AC voltage, resistance, diode)AC-RMS, AC peak-to-peak, frequency and pulse width for signal testing.High Voltage Capability: Displays up to 60 volts with 0.1 volt resolution.8 amp circuit breaker with automatic reset, no need to push a button.Three additional modes: min/max/sound monitoring.Automatic detection of positive, negative, open.Large color LCD display with easy-to-navigate user menus.Comes with an additional 20' extension cord.Look for shorts to ground and voltage.

• Features a built-in 8 amp circuit breaker to protect against circuit overload and overheating. This device conducts the battery current directly into the circuit you touch.
• When connected, the LED indicator on the front of the device will show the battery voltage. You can use it to determine a range of things. The alternator can be checked quickly by plugging it in and starting the car.
• It's also useful in situations where there's a large drop in mains voltage, or when you're checking fuses, etc. and you see low voltage on some branches, etc.
• Look for a short circuit, which in most cases will manifest itself as a blown fuse or a tripped electrical protection device. Use the probe tip to activate and energize each fuse contact. The contacts that trip the circuit breaker are shorted.
• To find a bad ground, probe a suspect ground wire or make contact with the probe tip. If the breaker has tripped, the circuit is most likely grounded.
