Description
Activates timed events by triggering the run-time clock to start.
When the input is enabled, the lamp is extinguished. The lamp can be
ignited only by sending a new method to the detector by using the
lamp button, or by rebooting the detector.
Adds a chart mark (at 10% of full scale) to either or both analog output
channels (Signal Out 1 and Signal Out 2) and is configurable.
Calculates an offset value that, when added to the sample signal,
makes the resulting baseline signal zero.
Method programmable analog output.
Minimum output voltage range: –0.1 to 2.1 Vac,
For sample rates of 10, 20, 40, or 80 Hz, this output runs at the
selected sampling rate.
For sample rates of 1, 2, or 5 Hz, this output runs at 10 Hz.
Controls a timed event or threshold level and is a user-programmable
auxiliary output.
