6.3.2 Measuring Frequency

The center section of the window changes to this:

You can enter any frequency between 10 Hz and 15000 Hz as full scale frequency. ST-12 measures the

frequency with a resolution of 0.1 % of the full scale frequency specified. So in LogWorks 0 Hz is always

0 Volt, and the full-scale frequency is equivalent to 5 Volt.

This functionality is also available for Inputs 3,4 and 5.

6.3.3 Measuring Speed

Select the Speed sensing function in the topmost drop-down list. The center section of the window

changes to:

With the radio buttons you can select to use metric (km/h) or US (mph) units. In the left drop-down list

you select the max speed to be measured. The ST-12 measures the speed with a resolution of 0.1 % of

the selected max speed.

In the right edit box you enter the pulses per mile the speed sensor produces. Speed sensors are

typically pulse sensors mounted either on the drive-shaft or wheel. To calculate the pulses per mile (or

km/h) click on the calculate button:
