An upper limit for the flow velocity can be entered (see section 16.2).
• Enter zero to deactivate the flow velocity check.
• Press ENTER.
A lower limit for the flow velocity can be entered.
• Select sign to define a cut-off flow depending on the flow direction. One limit is set for the positive and another for the
negative flow velocity.
• Select absolut to define a cut-off flow independent of the flow direction. A limit is set for the absolute value of the flow
velocity.
• Press ENTER.
• Select factory to use the default limit of 2.5 cm/s (0.025 m/s) for the cut-off flow.
• Select user to enter the cut-off flow.
• Press ENTER.
If Cut-off Flow\sign and user are selected, 2 values have to be entered:
• Enter the cut-off flow.
• Press ENTER.
All positive values of the flow velocity below this limit will be set to zero.
• Enter the cut-off flow.
• Press ENTER.
All negative values of the flow velocity above this limit will be set to zero.
If Cut-off Flow\absolut and user are selected, only one value has to be entered:
• Enter the cut-off flow.
• Press ENTER.
All absolute values of the flow velocity lower than this limit will be set to zero.
The thermal energy is the totalizer of the thermal energy rate.
• Select the unit of measurement for the thermal energy (J or Wh).
• Press ENTER.
• Select on to store and to output the values of the thermal energy totalizer and the volume totalizer during thermal energy
rate measurement.
• Press ENTER.
