Battery AA = 4 Pcs
1)Select engine type (4 or 2 CYCLE engine) from CYCLE selector .
2)Insert the PLUG into the SOCKET.
3)Connect the RPM INDUCTIVE PICK UP SENSOR to the HIGH TENSION WIRE of No. 1
SPARK PLUG ( or No. 2, No. 3… SPARK PLUG).
4)Push the MEASURING BUTTON, verify that the ” Monitor Indicator ” lights when the
signal input. Then the display will show RPM reading and update every second.
