Trigger States

and the

Trigger

Annunciator

Two segments are dedicated to the indication of the

trigger state of the meter. These are the TRIG and the ?

segment that follows it. The trigger state is always used

when a pyroelectric sensor is attached.

There are two possible trigger states when a pyroelectric

sensor is attached: “triggered” and “wait for trigger.” The

triggered state indicates that the meter is capturing laser

pulses. The wait for trigger state indicates an absence of

pulse triggers. When a pulse is captured, the trigger state

becomes active and the wait for trigger state becomes

inactive. If no pulses are captured within 1.67 seconds

since the last pulse was captured, the wait for trigger state
