Logic/Pulse
* Switching logic/pulse for each unit
The maximum use of the Logic function is 7 modules (112ch).
The maximum use of the Pulse function is 2 modules (32ch).
The maximum number of connections for each type of amplifier module to the GL7000
is up to 10 modules (112ch maximum).
Pulse : Rotation/Accumulating/Instant
Function : This mode counts the pulses for every sampling interval, and then converts
them to the RPM.
Span : 50, 500, 5000, 50 k, 500 k, 5 M, 50 M, 500 M .RPM/F.S.
Function : Mode for displaying the number of pulses accumulated for every sample
interval from the beginning of the recording.
Span : 50, 500, 5000, 50 k, 500 k, 5 M, 50 M, 500 M C/F.S.
Function : Mode for displaying the pulse count for every sampling interval. The
pulse count is reset for every sampling interval.
