Lab Exercises on Charging and Sensor Circuits
A charging system check is a standard practical. Students read battery voltage with the engine off and again at fast idle, and compare the rise. The Ignition and Charging System trainer lets them follow the alternator charging circuit first. The diode test then checks alternator rectifier diodes, relays and solenoids taken off a vehicle.
On the Fuel Injection Trainer - Multi Point EFI System, students read sensor voltages at the input/output panel and measure injector duty cycle as the simulated engine condition changes. The K-type probe measures radiator and hose temperatures during a cooling system check.
Frequently Asked Questions
What does 4000 count mean?
The display shows readings up to 3999 before it moves to the next range. On the 4 V range it reads to 0.001 V, so small voltage drops across switches and connectors show clearly.
Can it measure starter motor current?
No. The highest current range is 20 A, and a starter draws far more. Use the meter for smaller loads such as lamps, relays and battery drain with the vehicle switched off, and a load tester for starter current.
How is duty cycle used on a vehicle?
Many actuators, such as injectors and idle control valves, are switched on and off by the ECU. The share of on-time is the duty cycle. The analyzer reads it, with a plus or minus trigger to pick the switching edge.
Can readings be sent to a computer?
Yes. The RS-232 interface links the meter to a PC, so students can log readings during a test. The max and min record also holds the highest and lowest values seen while the engine is cranked or revved.
How is it different from an ordinary multimeter?
Besides volts, amps and ohms, it adds duty cycle and pulse width with trigger selection, a diode test for alternators, relays and solenoids, and a K-type temperature probe. These are the extra checks that tune-up work needs.
