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
Max Pulse Freq (Hz) and enter the
required value.
3.
Select
Flow at Max Freq and enter the
required value (gal/min).
4.
Select
Exit and press the ENTER key to return
to the
FLOW READING screen
