additions to the range test equipment produced by W. Eldred of Holderness Ro Hull.
A large meter deflection a relatively low resistance made possible by a three po tion switch dividing the to 0-50,000 ohm resistance ran into three on the ETT20 OF meter.
The dwellmeter is suital for I2v systems employing contact-breaker and igniti coil, and has separate sca for 2 and 4-stroke engines: Voltage regular circuits z included to eliminate t effects of battery volta which otherwise would up! the dwell readings.
Rev ranges of 0-4,500rprn four cylinder engines a 0-3,000rpm on six cylinc engines are catered for w the ETT 75 tachometer whi requires only two connectic to the engines.
