Page 3: Installation
Before beginning installation, the meter needs to be set to operating mode. To move the F2 out of transport mode, simply press and hold the display button for approximately five seconds. Depending on the factory settings of the calculator, it will then enter either Service Mode, or go directly into Operation Mode. - Page 4 A1 B1 MBus MBus 11 5 6 7 8 16 17/19 18 50 60 61 T his Calc ulator is equppped with pulse outputs Fig. 6, Labels on the on the backside of the F2 cover.

Page 5: Mounting On A Flow Sensor
2 Mounting The F2 can be mounted either on a wall, or on the flow meter itself. Mounting on a flow sensor The adapter allows the calculator to be mounted vertically or horizontally, see fig 2.1. Attach the calculator to the adapter with the provided retaining screw. -
Page 6: Installation Test
Watch the very lower left hand corner of the main display. If the flow sensor is supplying a pulse, it will result in a blinking square. If the F2 is receiving a pulse from the flow meter, then installation has been a success. - Page 7 3 Handling Display Every F2 is equipped with an LCD (Liquid Crystal Display). The data retrieved by the calculator is organized and accessible through display “sequences” visible on the LCD. The left-most digits indicate the current selected sequence. The right-hand digits show the relevant value for the currently selected sequence. A tap of the display button results in a move to the next value in the your current sequence.

Page 18: Decimal Placing F2
7 Appendix Displayed values on the F2 calculator will vary depending on the set pulse value, and follow the diagram below. Smaller pulse values result in readings to more decimal places than larger pulse values.
