When the unit is powered on, three red LED mode lights on the left side of display will appear. Each of these

lights aligns with particular function marked on the bezel face.

The unit has three operating functions:

1. Flow GPM or LPM - Actual Gallons or Liters per minute flowing. Flows up to 300 GPM or 1200 LPM will

display in single increments. Flows over 300 GPM or 1200 LPM will display every 10 units.

2. Flow TOTAL - Total gallons or liters flowed since unit was powered up. Figures displayed must be

multiplied X 100 to get a total.

3. Pressure PSI or kPa – Shows actual pressure.

At the time of power up, all three mode lights will appear with four zeros. In sequence a number value will appear,

followed by GAL/LPM, PSI/kPa, Pipe Size (2.5) and finally 0. This will be complete in a few seconds

The unit is now ready for operation.

tO reaD:

GpM/LpM: - Press and release left (flow) button to place mode light on GPM/LPM. The actual GPM or LPM

will appear on display.

tOtaL FLOW: - Press and release left (flow) button to place mode light on TOTAL. The figures displayed

must be multiplied by 100 to give gallons or liters flowed.

psi/kpa: - Press and release the right (pressure) button to place the mode light on PSI/kPa. Actual pressure

will appear on the display.
