Tachometer measurement
1) Connect the black test lead to “COM” socket and red test leads to the “VΩ T+ ” socket.
2) Set the selector switch to the “TACH×10” position for 3CYL, 4CYL, 5CYL, 6CYL, 8CYL, according to the engine cylinders. For any TACH signal with a given
frequency, in convention ignition system: RPM=120×freq ÷ CYL. in DIS ignition system : RPM=120×freq ÷ 2
3) Connect the red test probe to “BREAKER POINTS” or “-” terminal of IGNITION COIL, and connect the black test probe to “GROUND ” or “ - ” terminal of battery
4) Start the engine and read engine RPM, multiply the displayed reading by ten to get actual RPM.
NCV Sensitive Detection
Full-scale overload protection, if let the top of the instrument close to the conductor, when the live voltage ≥ 90V AC rms, the NCV red LED light and green LED light will light up alternately together with buzzer sound.
Data Hold & Backlight Display
Data hold and backlight buttons on the clamp meter make it easy to take readings while you operate. With the backlight display to read and record easily under dark areas.
1 x Test Leads
1 x Temperature Probe
1 x Carrying Case
1 x Manual
