Calibrating the pulse frequency range

The

Calculated Pulse Value field is automatically calculated as:

This value is often required to be programmed into the device that is receiving the pulses to enable it to calculate
the correct flow rate – for example, when connecting the pulse output to an energy meter.

1.

With the instrument operating in the

FLOW

READING mode, press the Pulse function key
to access the

PULSE OUTPUT screen.

2.

Select
