AUXILIARY METER

Press ELECTRICAL, SELECT

Auxiliary Meter

, and press NEXT. This general purpose meter

is useful for measurement of a variety of voltages and sensor signals.

Connect the Auxiliary Meter Lead to a voltage or sensor output. Readings are referenced to

the negative vehicle battery terminal through the Diagnostic Center Battery Clip leads. The

DC voltage range is 0 to ±20 volts, with 0.01 volt resolution, and a 10 megohm input impedance.

AC signals up to 50 volts peak-to-peak can be measured. Hertz up to 999 and duty cycle %

are also displayed.

This test screen shows all components of a measured signal simultaneously. The meter is

quite sensitive, so while measuring a DC voltage, you may also see stray AC signals displayed

as Volt P-P and Hertz. These stray signals can be ignored and will not interfere with

measurement of an AC signal to which you are directly connected.
