Scope Multimeter

Operation and Controls

To turn the filter on and off, select the 

Filter 

icon.

Invert 

The Invert feature is used to switch signal polarity, so the trace appears upside down (inverted) on 
the screen. This is typically used when measuring amperage using the low amp probe, or high-
voltage signals like, secondary ignition.

Example: A signal that normally rises from 0 to +5 volts, if inverted would show falling 
from 0 to –5 volts.

To turn inversion on/off, select the

 Invert 

icon. 

Coupling AC

Coupling AC subtracts the average value of a signal so that small variations can be displayed in 
the waveform. This is accomplished by blocking the direct current (DC) portions of a signal in 
order to amplify (show) the alternating current (AC) portions of the signal, without driving the trace 
off of the screen.

Using coupling AC can be helpful when testing and diagnosing alternator ripple or fuel pump 
amperage, by allowing you to see any abnormal small variations or events.

To turn coupling AC on and off, select the 

Coupling AC

 icon. 

Trigger

NOTE:

i

The Trigger feature is only available in the lab scope function. 

A trigger can be used to stabilize a changing or erratic signal (a signal that may flicker or drift as it 
refreshes), so that it is easier to view or diagnose. This stabilization effect is accomplished by 
basically displaying the same part of the trace repeatedly from the same starting point, thus the 
flicker or drift is minimized which makes the trace appear more consistent or static. 

A trigger is basically a “specific point” on the display, at which a trace will start to display (start the 
sweep) if it crosses that point.
