Scope Multimeter Operations
When used in conjunction with the VERDICT M2 Data Acquisition Device the Scope Multimeter
module provides all the tools needed for performing electrical and electronic circuit tests and for
monitoring signals and circuit activity. The Scope Multimeter works interactively with other
modules. Selecting “View Meter” from a Component Test or Scanner test launches the Scope
Multimeter module.
The M2 Data Acquisition Device is designed to work with the high-voltage hybrid vehicle batteries
and circuits, which makes it a Measurement Category III and IV meter and raises additional safety
concerns. For your safety, adhere to the safety messages posted below and those in the
accompanying
Important Safety Information
.
:$51 ,1*
Risk of electrical shock.
• This product is intended for Measurement Category III (1000V) and IV (600V).
• Do not exceed voltage limits between inputs as indicated on the rating label.
• Use extreme caution when working with circuits that have greater than 40 volts DC or
24 volts AC.
• Do not connect Inductive RPM Pickup, Secondary Ignition Clip-on Wire Adapter, or any
other probe to a damaged or un-insulated conductors.
• Always wear properly rated rubber insulated gloves when required or appropriate,
particularly when working with voltages exceeding 40 volts DC or 24 volts AC.
• Use only appropriate (Category III or IV) Snap-on components, such as test leads, scope
leads and auxiliary components with meter and scope products. Do not use aftermarket
“equivalents” or alternate leads of unknown origin.
• Use only Snap-on suggested components that are in good working order. Do not use
components that show extreme wear or are visibly damaged. Make sure the
components are properly rated for the task.
• Always examine the instrument for signs of damage before use. Do not use devices that
show cracks or other defects that may allow for high voltage exposure.
Electrical shock can cause personal injury, equipment damage, or circuit damage.

Risk of equipment or circuit damage.
• Read the Safety Information provided for important warnings on the use of this product
• Disconnect test leads from any circuit being tested before changing functions. Always
disconnect the live test lead before disconnecting the common test lead.
• Never perform resistance, diode, or polarity tests on a live circuit.
• Unless specifically directed by the test procedure, make sure the ignition is off before
connecting or disconnecting connectors or any vehicle electrical terminals.
• Remove the amp probe when not in use.
• Do not create an electrical connection between battery terminals with a jumper wire, or
your scopes and/or meters.
• Do not ground any electrical terminal that has or may have power.
• Do not allow battery gases or acid to contact tester housing.
Improper use can cause equipment or circuit damage.
