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 t he engine is runn ing, without loading
the circuit being tested. This ensures that the signal
voltage measurem ent will not be affected by the
voltmeter.
