MinuteMan Plus Multi-application Electrical System Tester

Battery Testing - The way it has been: You customer brings in a dead battery and you have to charge it up to test it. Then, if it's a keeper, you have to recharge it. MinuteMan Plus tests discharged batteries down to as low as two volts, under load, and it won't discharge a charged battery, under load, and it won't discharge a charged battery you are testing. Since the tester has its own internal, rechargable 6-volt battery, no owner source is needed, making roadside testing a snap. MinuteMan Plus tests all 12-volt automotive-type batteries with cold cranking amp ratings of 100 to 1,500. The tested battery's decay and recovery specs are compared with a database of hundreds of batteries, stored in the tester's memory. Every possible battery fault condition is stored in the database. The results of each battery test are compared to the MinuteMan Plus database, and a diagnostic decision is made by the microprocessor.

Starter Testing - The MinuteMan Plus display shows cranking volts and amps, and indicates either "Good Starter" or "Bad Starter." Excessive starter current draw revealed can indicate a possible defective starter. Excessive engine drag due to tight or damaged bearings or piston drag, can also cause abnormally high starter draw.

Charging System Testing - Checks the charging system at high RPMs and at idle, and stores the data. Results show regulator volts, peak amps, and diode condition. MinuteMan Plus utilizes waveform analysis when testing alternator diodes, which provides more accuracy than the commonly used "ripple voltage" tests.

Battery Tachometer Capability - Unique, patented direct-from-battery technology gives you tachometer readings without having to make complicated connections to the ignition system. Provides battery-sensing measurements to 3,000 RPM, with 1 RPM resolution.

Ammeter/Voltmeter Functions - MinuteMan Plus includes constantly registering voltmeter and ammeter displays. Ammeter display reads ±0 to 1,000 amps, 0.1 resolution. "Zero amps" sets the amps probe reading to zero. This quick step ensures accuracy prior to each charging and starting test. Voltmeter display reads ±0 to 40Volts DC with .01 resolution.
