The following sections assume a basic knowledge of the VISAIC utility and GPIB. To access the VISAIC in MAX go to Tools»NI-VISA»VISA Interactive Control. For other instrument driver types, the examples will be available from the Application Examples subpalette from the corresponding instrument driver. In the following figure we have opened the Agilent 34401 Read Multiple Measurements.vi example that comes with the Agilent 34401 instrument driver. Finally, press the «Read» button to read back the response from the instrument. Engine Braking– Rows P1, P2, and even part of P3 can be corrupted by engine braking. These productivity tools help you focus on developing your test applications instead of trying to track down obscure problems or establishing communications with your instruments. Figure 5. Launch VISAIC Quickly Determining GPIB Addresses When VISAIC initially runs, it automatically finds all of the available resources in the system and lists the instrument descriptors for each resource under the appropriate resource type.

Holding a constant throttle position from low to high RPM is best. Figure 3. Attributes Tab for an Instrument If your device did not appear, refer to GPIB Installation/Configuration Troubleshooter. Simply use the refresh (View»Refresh) to check if a particular instrument is listening at its assigned GPIB address. If it is not, then you know to check cables, confirm power, and verify that the instrument is working properly. If there is a problem, you no longer see your device. The monitor window will appear and display all inputs to the ecu. However, LabVIEW Plug and Play instrument drivers are distributed with their block diagram source code, so you can customize them for a specific application.

This guide will not cover the physical installation of the sensor in the exhaust system. This will often show up on the LM1 display as a dancing AFR reading from rich to lean. On the logging this will be averaged out, so you won’t see it. If you have misfires in a particular area, do not use the logged data at face value. When lifting the throttle during engine braking, the ECU does not inject any fuel.
