Changing analog min & max will not affect the instrument measurement range. Analog out range can
be adjusted to narrow or widen the resolution.

Pulse
The VPFlowScope In-line 3/8" flow meter features a low-frequency active pulse output. The pulse is a
‘non potential’ free output as it acts like a controlled current output. To make it passive, an external
isolator can be used.
The pulse output is connected to the internal totalizer value. When the totalizer has increased by the
pulse interval, the pulse will be generated.
When the analog output is in pulse mode, analog min holds the pulse interval, meaning value
represented by a single pulse.
