STARTING RECORDINGS
4.2.2
Stop on Digital Signal
Recording parameters can be programmed so that a recording will stop as soon
as the digital input detects a "low". A "low" is a voltage below 0.8V!.
An "open" digital input is held low by an internal resistor.
4.2.3
Stop on Analog Level
Recordings may be programmed to stop on a signal outside a programmed
level.
An example may be in place:
A voltage being monitored should vary between 4V and 8V. Any value below
4V or above 8V indicates a malfunctioning. The recording should stop after
such an event so that data can be transferred to computer for analysis.
"Stop on level trigs" must then be programmed to 4V and 8V as the lower and
upper levels.
4.2.4
Stop when Memory Full.
Recording will automatically stop when the memory is full.
Unless of course endless or circulating memory is programmed, in which case
the memory will "wrap around" and only stop on key stroke or stop trig.
