Programming a Frequency Output
This choice produces a frequency pulse that is proportional to the output measurement.
4. Use the [
and [ and [F1]-[F4] keys to specify the desired Output Measurement parameter. See Table 21 on
page 36 for a description of the available options.
Note: The measurement units that appear in these prompts are those selected in the SYSTM menu earlier in this
chapter.
5. Enter a value for the Base (low end) of the frequency output range and press [ENT].
6. Enter a value for the Full (high) end of the frequency output range and press [ENT].
7. Enter a value between 1 and 10,000 for the Full Scale Frequency and press [ENT].
8. Use the [F1]-[F4] keys to select the desired Error Option, the way the display responds during an error condition.
Available options are shown in Table 23. Then skip to step 12 on the next page.
