Digital Multimeter (Fluke 88)

Figure 516 ZTSE4357
The Fluke 88 Digital Multimeter (DMM) is used to
troubleshoot electrical components, sensors, injector
solenoids, relays, and wiring harnesses. The DMM
has a high input impedance that allows testing of
sensors while the engine is running, without loading
the circuit being tested. This ensures that the signal
voltage measurement will not be affected by the
voltmeter.
Read all safety instructions in the "Safety Information" section of this manual before doing any procedures.
