Chapter 8 Scope and Multimeter

Operations

The Scope Multimeter function provides all the tools needed for performing electrical and

electronic circuit tests and for monitoring signals and circuit activity. The Scope Module easily

separates from the Diagnostic Tool and connects with a USB cable so that test results can be

remotely monitored as you perform other tasks.

The Scope Multimeter function works interactively with other functions. Selecting “View Meter”

from a Guided Component Test or Scanner Test opens the Scope Multimeter function.

Risk of electrical shock.

• Read the Safety Information provided for important warnings on the use of this product

• This product is intended for Measurement Category I (for example, automotive 12V

systems), do not use this product for Measurement Categories II, III, and IV.

• Measurement Category I is for performing measurements on circuits not directly

connected to MAINS or MAINS circuits (an example of a MAINS circuit is 120V AC or

240V AC household or industrial electricity), do not connect this product to MAINS or

MAINS circuits.

• Do not apply the Black Ground Lead to test points other than ground/system return/

vehicle chassis.

Electrical shock can cause personal injury, equipment damage, or circuit damage.

IMPORTANT:

Maximum rated transient over voltage impulse is 500 volts, do not exceed the rated

transient over voltage.

8.1 Using the Scope Module Remotely

The Scope Module (M4) module can be undocked from the Diagnostic Tool, and used remotely to

increase the range of mobility while monitoring signals on a test vehicle. An A/B type USB cable

(supplied) is used to connect the Scope Module to the Diagnostic Tool when used remotely.

As general practice, the Scope Module should only be undocked from the Diagnostic Tool when it

is off. To prevent accidental loss of data, make it a practice to first save the current data if desired,

then select either the Power Off or Back icon from the Scope Multimeter toolbar to stop meter

operation. Power Off saves the current settings, but does not save data. Settings are not saved if

Back is selected.
