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.
