BT-705A Pickup Lead Accessory for Digital Multimeter, Signal Pick Up Adapter Used for Automotive Meter with Frequency 10-400Hz
??¡¼Important Note¡½-This RPM signal pick up must works with automotive multitester meter or oscillograph with signal input function, for engine systems diagnosis and adjustment.
??¡¼Perfect Engine Analyzer¡½-Inductive clamp lead is compatible to be used with BTMETER Automotive DMM BT-770K, BT-90K, BT-6688D, and measure car frequency 10-400Hz and tach range 300-1200 RPM .
??¡¼Versatile Clamp Hole¡½-To measure secondary end conductors of high voltage ignition coil spark, bigger hold is more useful for various size of spark plug wires.
??¡¼Easy Operating Steps¡½-Clamp the spark plug wire with the mark ¡°¡æ¡± on the inductive pickup tool pointing to the spark plug for engine speed measurement.
??¡¼Notice in Measurement¡½-The distance between the spark plug and the clamp of the instrument must be less than 3.93 inch (10cm) during test, and the ignition frequency of the engine ignition system must be between 10Hz and 400Hz.

Tips for BT-705A RPM inductive clamp:
?? The pick up test lead is designed for general application.
?? It only works with Signal Input Function digital multimeter.
?? Perfectly work with BTMETER BT-770K, BT-90K, BT-6688B Automotive Digital Multimeter
?? Detection Area: Secondary End Conductor of high volt ignition Coil.
Operating Instruction:
?? Step 1. Connect the clamp of the instrument to a spark plug wire with the mark on the instrument pointing to the spark plug.
?? Step 2. Connect the plugs of the instrument to the input terminals of the automotive meter.
(The black plug of this instrument should be connected to COM jack of the automotive meter.)
Set the automotive meter in corresponding measuring range.
Then you can read the RPM value on the multimeter display.
If no reading is received, unhook the clamp, turn it over and connect again.
