it will find dead cylinders.. it drops cylinders 1 by 1 until you find the 1 that does not drop the RPM as much... RPM should drop 50 ( IIRC ) for every cylinder as an average. if a cylinder drops less, it is weaker.... the balance testers I have used electronicly killed the cylinders and only used a tach signal and a wire to the coil.. so that tester is quite old... also used a snap on osciliscope that had a power balance test.. it was automatic and had a percent display for each cylinder...
