Lutron Automotive Tester DM9030 is a specialized digital multimeter used for vehicle electrical and engine diagnostics.
Features :
- Multi function measurement. DCV, ACV, DCA, ACA, OHMS, RESISTANCE TEMPERATURE, Hz, RPM, DWELL, 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.
