4.5.7 Two-Wire Pulse Timing
By parallelling the START and STOP inputs, pulse type operations may be timed using only a single pair
of sensing leads.
The rising edge of a voltage pulse, for example, would cause a start trigger, and the falling edge would cause
a stop trigger. This allows measurement of the duration of a voltage pulse.

4.5.8 Timing in Cycles
The [TIME] button toggles between timing in seconds and timing in cycles display.
Timing in cycles is calculated from the timer (seconds) reading and the present frequency. In line frequency
mode, there must be a voltage output to obtain a frequency measurement, and subsequently a timing in
cycles value.
If the frequency changes during a test, the time in cycles value will assume that the frequency has always
stayed at the latest value (time in cycles doesn’t actually count power cycles--it’s a calculated value).
