Auto Multi Meter

This Automotive Multi Meter (AMM) was designed solely for Automotive Technicians to troubleshoot all electrical problems in the vehicle. Applicable on 6V, 12V or 24V system, also it can be used to check Amps draw directly at the fuse (Mini, ATC or Maxi Fuses) without  removing it to measure parasitic drain current using parallel method at the fuse box.

Exclusive Invention

This Multi-meter has Two Options when performing Amps Draw Measurement:

1.    Direct Test Amp measurement- Test probes placed parallel to the fuse during measurement.

2.    In-line Amp Draw test with the circuit. 

Unique Features

• Direct Amp Draw measurement - it measures Amp draw directly from the two expose points of the fuse (either Mini, ATC or Maxi) while the circuit is operating.

       The test is is done without removing the fuse on the fuse box, the tester will display  results and hold the reading during testing. 

Supplied with Detachable probes which can be set according to the test points of a fuse by sliding the two probes together to suit Mini, ATC, or Maxi fuses.

• In-line Amp Draw Test with the circuit

This test measure Amps in line (in series) with the operating circuit. 

In two ranges: 1mA ~ 999 mA and 1A ~ 30A. 

The smaller range (1mA~999mA) is very useful in measuring parasitic drain when the vehicle is OFF.

The larger range (from 1A up to 30A max) is for testing fans, wiper motors, etc.

Additional Features

• On / Off Button

•  Zero Calibration

•  LED Traffic Light Indicator

•  Result – Hold Display

•  12/24 System Auto Selection
