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
