- Page 2 (indoors). The ambient temperature must be within 5 °C…55 °C. The flow sensor, however, may be installed in condensing environments. Maintenance and repair The flow sensor and the temperature sensors must not be separated from the calculator. Repairs require subsequent reverification in an accredited laboratory.

In order to prevent cavitation, the operating pressure at MULTICAL® 302 must be min. 1 bar at q and min. 2 bar at q . This applies to temperatures up to approx. 80 °C. MULTICAL® 302 must not be exposed to pressure lower than the ambient pressure (vacuum). Kamstrup A/S • 55121351_D2_GB_04.2015... -

The meter is most sensitive to air bubbles in the water when the plastic case points upwards. Therefore, this mounting position ought only to be used in installations with high operating pressure and automatic ventilation like e.g. direct connected district heating.

However, INFO code 128 indicates that the battery voltage is too low. The battery cannot and must not be charged and must not be short-circuited. Used batteries must be handed in for approved destruction, e.g. to Kamstrup A/S. Kamstrup A/S • 55121351_D2_GB_04.2015... -
Page 11: Testing The Function
If the meter has integrated wireless M-Bus, it is possible to select between Mode C1 or Mode T1 OMS. Mode C1 is used in connection with Kamstrup's reading systems and in general for drive-by meter reading. Mode T1 OMS is used in connection with OMS-based stationary networks. -
