.
During the heat flow measurement
During the heat flow measurement, it is possible to transmit and store the values of the heat quantity totalizer and of the
volume totalizer. Select
Special Funct.\SYSTEM settings\Measuring\heat+flow quant.
.
11.2.1 Overflow of the Totalizers
The overflow behavior of the totalizers can be set:
Without overflow:
• The value of the totalizer increases to the internal limit of 10
38
.
• if necessary, the values will be displayed as exponential numbers (±1.00000E10). The totalizer can only be reset to zero
manually.
With overflow:
• The totalizer will be reset to zero automatically when ±9999999999 is reached.
Select
Special Funct.\SYSTEM settings\Measuring\Quant. wrapping
.
Independently of the setting, the totalizers can be reset to zero manually.
11.3 Settings of the HybridTrek Mode
The HybridTrek mode combines the TransitTime mode and the NoiseTrek mode. During a measurement in the Hy-
bridTrek mode, the transmitter automatically toggles between the TransitTime mode and the NoiseTrek mode in order to
receive an optimal measuring result when the gaseous or solid content increases temporarily.
If
on
is selected, the values of the totalizers will be stored and used for the next measure-
ment.
If
off
is selected, the totalizers will be reset to zero.
Select
on
to store and transmit the values of the heat quantity totalizer and the volume to-
talizer during the heat flow measurement.
Press ENTER.
Select
on
to work with overflow. Select
off
to work without overflow. Press ENTER.
Note! The overflow of a totalizer influences all output channels, e.g., data logger, online transmission of da-
ta.
The transmission of the sum of both totalizers (the throughput

Q
) via an output will not be valid after
the first overflow (wrapping) of one of the corresponding totalizers.
To signalize the overflow of a totalizer, an alarm output with the switching condition
QUANT.
and the
type
HOLD
have to be activated.
Note! Due to its higher measuring accuracy, the TransitTime mode should be used preferentially over the
NoiseTrek mode.

Select
no
to deactivate the automatic toggling between the TransitTime and the NoiseTrek
mode. If
no
is selected, the NoiseTrek mode can only be activated and deactivated manu-
ally during the measurement.
Select
yes
to activate the automatic toggling between the TransitTime and the NoiseTrek
mode. If
yes
the NoiseTrek mode can also be activated and deactivated manually during
the measurement.
Press ENTER.
This display will only be indicated if the NoiseTrek mode is enabled.
