1.3.3.3 Low Frequency Test

To perform the low frequency test, follow these steps:

  1. Set the probe voltage of the oscilloscope to 2V/Div.
  2. Adjust the timing to see an entire wave period, see the following figure.
    Figure 1-13. Entire Wave Period
  3. Measure the frequency of one period of the wave form. Frequency measured must be within the specified range. Otherwise, the programmer is out of calibration and needs servicing.
    The following figure shows the allowable range of the of low frequency test.

  4. To proceed to the next test, on the SS4 programmer, press the START push button.
