5.5. Verifying the installation and configuration
After installation of the meter, let the measured working medium flow through the flow sensor. The heat meter's LCD should display the measured
parameter values on the calculator display, if the heat have been properly installed (calculator, flow sensor and the temperature sensors). If the
measured parameter values are not displayed correctly, it is necessary to verify the installation.
5.6. Sealing after the installation
The meter must be sealed once it has been installed as explained in p. 4.2 to prevent unauthorized dismantle, removal or altering the device
without evident damage on the meter or its seals.
Installer's security seals:
butterfly, wire or lead seals to bind the top and bottom parts of the calculator enclosure (see Fig. 12.1.);
seals on the protective pockets and the mounting bolts of the temperature sensors (see Fig. 12.2. to Fig. 12.7.);
seal also the flow sensor's connection with the pipeline ends (for example couplings).
6. Operation
6.1. Operating the LCD display
You can cycle through indications displayed on the meter LCD by pressing the control button in the lower part of the calculator front panel.
