FEATURES
Multi function measurement. DCV, ACV, DCA, ACA, OHMS, TEMPERATURE, Hz, RPM, DWELL ANGLE, DIODE, CONTINUITY BEEPER.
RPM (TACH) measurement by inductive pickup for more convenient & accurate readings of both conventional and distributorless ignitions.
RPM (TACH) used the " Secondary Tach. " measuring method, no matter what cylinder no is.
Accurate DCV/ACV, DCA/ACA and resistance measurement, wide range of automotive electronics tests.
Duty cycle (%) with Dwell conversion chart for electronic fuel injection and feedback carburetors.
Diode test quickly measures the forward bias voltage drop of alternator rectifiers and other diodes.
Continuity beeper keeps whenever probes touch a continuous circuit. Helps find shorts and open wires.
10 Mega ohm impedance protects Mega ohm computer circuit.
Frequency measurements with adjustable trigger point for testing MAF, MAP & ABS SENSOR.
Rotary function switch, easy operation.
Large size LCD display.
Built-in overload protection for most ranges.

導通蜂鳴測試 (CONTINUITY BEEPER)
A CONTINUITY TEST BEEPER IS STANDARD. SO WHEN ARE CHECKING CIRCUITS FOR SHORTS OR OPENS, YOU DO NOT HAVE TO LOOK AT THE METER. THE BEEPER SOUNDS IF CONTINUITY IS PRESENT.
二極體 (Diode TEST)
- Open circuit voltage is approx. DC 3V max.
