Upload Setup; Using Realtime Graphing To Assist In System Checkout; Normal Analog Sensors; Position Sensors - Edelbrock QwikData 91001 Manual

Upload Setup

An upload is automatically performed whenever the PC establishes communications with the QwikData box.
You can manually instruct the system to upload the contents of the box by choosing this selection from the "Setup" menu.

Using Realtime Graphing to Assist in System Checkout

After wiring and configuring your system, you will want to check that each channel is correctly installed.

Normal Analog Sensors

Analog sensors are the simplest case and in most cases can be checked out without even starting the vehicle. Use a torch or heat gun
to heat up the area around each EGT and watch that the response is as expected on the Realtime graphs. Oil pressure sensors can
be checked out by priming or cranking the engine.

Position Sensors

These can be can be checked by physically moving the elements and watching the Realtime graphs. If you want to calibrate the
sensors (e.g. calibrate throttle position to read between 0 and 100 percent) -go back to the "Analog Channel Menu" and select and set
each channel so that the output reading is equal to the input . Example - for a 0 to 5 volt sensor, set the output to read 0 to 5. Download
the new setup and go back to the Realtime Graph Display. Move the position sensor between the min and max positions and record
the two values, (which is now a voltage) displayed. Go back to the "Analog Channel Setup" screen and now instead of entering (0), (0)
and (5), (100) as the calibration values, enter new minimum voltage, (0) and new maximum voltage, (100) as the number pairs.
Remember to save your new setup to your hard drive and download it to the QwikData unit.

RPM Inputs

Tach input signals need to be checked with the engine running. Start the engine and verify that the Realtime Graph displays the correct
RPM.

Pure Digital Inputs

Switch the circuit being monitored on and off ( e.g. depress brake pedal for brake on/off input) while watching the Realtime graph.
Check that the graph changes state of Wheel & Shaft Speed Sensors. Since the minimum frequency that can be read with the default
timer resolution is 6 Hz, speed sensor inputs are probably most easily checked out by setting the Digital Channel "Type" as "Pure
Digital" temporarily, then download the setup to the QwikData unit. Go back to the Realtime Graph Display and monitor the display
while slowly rotating the shaft. You should be able to watch the output change when the magnet passes the sensor. After you have
verified the sensor, change the channel "Type" back to the proper type and download the setup to the QwikData unit again.

Viewing Realtime Data

Selecting this item from the "View" menu will bring up the Realtime trend graph and data will
start displaying immediately. Data is updated on the display at approximately 4 times per
second.
