To test the frequency, connect a frequency meter to the pulse output terminals and proceed as
follows:
To test the pulse output, connect an external counter to the output terminals. When testing the
pulse output, the operator has the choice of the following pulse widths: 0.4 ms, 1.0 ms, 10.0
ms, 100.0 ms and 500 ms. The operator should choose the pulse width that best matches the
performance of his external pulse counter.
Connect a pulse counter to the impulse output and proceed as follows:
