Page 5: Installation
1 Installation At delivery F2 is delivered in the transport mode. This means that only the real time clock is active. No measurements take place in this position. The transport mode is indicated by a "no" in the upper left hand corner. -
Page 6: Connections
Connections The screw terminal blocks are situated under the cover on the rear side of the calculator. Note: The covers retaining screws is protected by a labelled sea. When the calculator is mains powered the will be a permanent power cord. Note: BR431 power supplied, flow sensor has to be connected to +3V. -
Page 7: Mounting
2 Mounting F2 can be mounted either on the flow sensor or wall mounted. When the calculator is mounted on the flow sensor, the adapter provided for this purpose has to be used. Mounting on a flow sensor The adapter allows the calculator to be mounted vertically or horizontally, see fig. -
Page 8: Installation Test
Installation test When installation has been completed simple test can be done to verify that the calculator has been installed correctly. Wait until the flow sensor supplies a pulse. This shall result in the symbol for flow sensor pulse, a square shown on display will flashing once. -
Page 9: Handling
3 Handling Display The F2 has an LCD (Liquid Crystal Display), see fig. 3.1a below. The values are displayed in sequences. The left-hand sequence digit shows the relevant sequence. The right-hand sequence digit shows which value in the sequence is being displayed. A short button depression results in a move to the next value in the relevant sequence. -

Page 15: Verifying The Calculator
5 Verifying the calculator Verification of the calculator's measurement accuracy is undertaken in the test mode, where the energy value/flow sensor pulse is issued via the HF-output at the service adapter. For each flow sensor pulse, measurement takes place on the temperature sensors and a pulse burst corresponding to the measured energy of the meter is issued. -

Page 19: Pulse Outputs ( Either Pulse Outputs Or Pulse Inputs On F2)
7.10 Pulse outputs (either pulse outputs or pulse inputs on F2) F2 can be equipped with two pulse outputs as standard of the type “Open collector” for energy (pulse output 1) and volume (pulse output 2). The last digit and the energy unit will reveal the pulse weight of the pulses. Example: sequence “10”... -
