5. The TA4000.04 oscilloscope probe is used when very accurate measurememts are
required. This is the only probe that can be calibrated. For normal automotive testing,
calibration wil not be necessary when using the alternative leads and probes supplied.
3. Attach the tip of the probe and ground clip to the Probe Compensator Connector. Click
the button. A square wave will be displayed within several seconds. (Approximately
1 kHz, 2V, peak- to- peak).
4. Inspect CH2 ,CH3 and CH4 with the same method. Repeat steps 2 and 3.
Self Calibration
The self calibration routine lets you optimise the oscilloscope signal path for maximum
measurement accuracy. You can run the routine at any time, but you should always run
the routine if the ambient temperature changes by 5° or more. For accurate calibration,
turn on the oscilloscope and wait twenty minutes to ensure it has warmed up. To
compensate the signal path, disconnect any probes or cables from the input connectors.
Then, access the “Utility -> Calibration” option and follow the directions on the screen.
The self calibration routine will take several minutes.
