Digital Multimeter Opens in a new tab. |
1. | Select the Scope Multimeter icon on the Home screen. |
Select one of the following options:
- | Digital Multimeter (DMM) |
- | Graphing Multimeter (GMM) |
- | Lab Scope |
- | Ignition Scope (Secondary Ignition Tests) |
- | Presets |
A submenu of scope or meter configuration will display.
2. | Select a configuration to continue. |
The following topics in this section primarily describe the general setup and control operations for the Lab Scope and Graphing Multimeter functions. The Digital Multimeter is not covered as setup and operations are intuitive.
3. | For information on the Ignition Scope function, see Ignition Scope. |
4. | For information on the Presets function, see Presets. |
Standard “safety type” test lead jacks are located on the top of the diagnostic tool, and are compatible with many test leads and probes. Insert the applicable test lead or probe terminal end into the jack to compete the connection.
For information on test leads, see Test Leads and Accessories.
To avoid damaging test leads, do not pull on the wire when removing the leads from their jacks. Pull only on the lead terminal end.
1. | Auxiliary (DB9) Connector The auxiliary connector is used for connection of the optional RPM inductive pickup and the pressure transducer split lead adapter. For additional information contact your sales representative and see, Using the Scope Module Extension Cable. |
2. | Channel 4 Jack |
3. | Channel 3 Jack |
4. | Channel 2 Jack |
5. | Channel 1 Jack |
6. | Common (Ground) Jack |
7. | USB Jack (not shown - used for remote operation) |
In situations where the testing connection points are not easily accessible, the Scope Module easily separates from the diagnostic tool (connected via extended length USB cable) allowing you to monitor the results remotely. This increases the range of mobility for the diagnostic tool while monitoring signals on the test vehicle. Use the Type A/B USB cable, which is provided with your kit, to make the connection.
When used remotely, the scope module must be connected to the lower (black) USB jack on the diagnostic tool.
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.
If the Scope Module:
- Is undocked from the diagnostic tool when it is on, or
- Is exposed to a electro static discharge (ESD) while it is being used remotely
the following will occur:
• Communication between the diagnostic tool and the Scope Module will be terminated.
• All current data and settings will be lost.
• An error message (e.g. Meter/Scope Not Found) will display to indicate that Scope Module communication has terminated.
When communication is reestablished (after a communication loss), the Scope Multimeter application is restarted and the Scope Multimeter main menu page is displayed.
1. | Depress the Scope Module release tab located on the top of the diagnostic tool. |

2. | Slide the Scope Module off of the diagnostic tool. |
3. | Locate the USB jack on the bottom of the Scope Module . |

4. | Connect the square end of the USB cable to the jack on the Scope Module. |
When used remotely, the Scope Module must be connected to a USB jack on the diagnostic tool.
5. | Connect the rectangular end of the USB cable to a USB port on the diagnostic tool. |
The Scope Module is now ready for remote use.
Certain tests may display a confirmation prompt asking “Do you wish to calibrate this probe?” before continuing with the test. As general practice, it is important to ensure the test probe is calibrated before testing, to ensure accurate results.
Typical resistance, pressure, and vacuum tests will display the calibration message, reminding you to calibrate the probe. To perform the probe calibration, select Yes at the prompt and continue to follow the onscreen instructions to complete the calibration.
Probe calibration confirmation
Example:For the ohms (resistance) calibration process, once completed, zero ohms should be displayed when the leads are connected together. When the leads are separated, the upward arrows on the display indicate infinite resistance or an open circuit.
Typical Ohms “zeroed” calibration screen and calibration icon
During an ohms test or a pressure test, a manual probe recalibration can be initiated by selecting the Calibration icon from the Control Panel.
