The AR-7240B is an analog engine tachometer featuring the automatic full scale switching function. When engine rotation is measured in the low scale, such as idling speed adjustment, it can be observed in the low range with 200 r/min scale. And the meter scale can be switched automatically to the high range with 10,000 r/min scale when engine rotation is increasing up into high speed load domain.

For gasoline engine measurement, the IP ignition pulse detector (for primary or secondary side) can be set up byseries one-touch attachment. For diesel engine, the VP-202/VP-1220 detector can be used. In addition to AC power supply, optional DC power supply is available and enables the AR-7240B on-board use or any place to measure. The analog output helps to figure out fluctuation of rotation speed, and pulse output can be applied to process the number or cumulated rotations of ignitions.
