Hauptmerkmale
-
Multimeter Mode
Quickly identifies the voltage, resistance and polarity of the tested component, and checks continuity.
-
Oscilloscope Mode
Displays voltage, frequency and time curves for analyzing circuit behavior.
-
Relay Test
Tests 4-pin and 5-pin automotive relays.
-
Component Activation
Sends an activation signal to lights, motors and other onboard electrical devices.
-
Injector Pulse Test
Outputs pulse signals to injectors in four pulse modes to check injector condition.
-
0–5 V Supply With Voltage Alarm
Set an output voltage to verify a component’s wiring; the tester alarms if a short or fault pushes the voltage above or below the set value.
