Tachometer: Testing and Inspection
Inspection
Tachometer Inspection
1. Insert an engine speedometer probe in the connector from the harness side, and attach the engine speedometer.
NOTES: For tachometer inspection, use of a fluxmeter-type engine speedometer is recommended. (Because a fluxmeter only needs to be clipped
to the high tension cable.)
2. Compare the readings of the engine speedometer and the tachometer at every engine speed, and check if the variations are within the standard
values.
Standard value:
Engine speed............................................................................................................................................................................ Indication Variation
1,000....................................................................................................................................................................................................± 100 rpm
3,000....................................................................................................................................................................................................± 150 rpm
5,000....................................................................................................................................................................................................± 250 rpm
6,000....................................................................................................................................................................................................± 300 rpm
