7.2.5.6 Mass flow QM limit hysteresis
The hysteresis of the QM limiting values is the flow rate in percent based on the upper-range value and
indicates the value which must fall below or surpass the set limiting values in order to activate or deactivate the
function. The hysteresis of the QM limiting values can be set in 1-percent increments from 0 to 10 %. After
choosing the Mass flow QM limit hysteresis function and pressing “Enter”, the following selection field will be
displayed:
Mass flow limit
Hysteresis 00 %
The current hysteresis value will be displayed and can be changed by toggling the arrow keys.
Confirm the entry with “Enter”.
7.2.5.7 Volume flow QV unit
This function allows the operator to define the physical unit for all display functions and the upper-range value
for volume flow. After choosing the “Volume flow QV unit” function and pressing “Enter”, the following
selection field will be displayed:
Volume flow QV unit
in [m³/h]
One of the following units can be selected:

m³/d, m³/h, m³/min, m³/s, cm³/h, cm³/min,cm³/s

l/h, l/min, l/s,

USG/h, USG/min, USG/s,

UKG/h, UKG/min, UKG/s

USB/d, USB/h, USB/min, USB/s,

MG/d

ft³/d, ft³/min, ft³/s

acft/s

floz/h, floz/min, floz/s

xx/h, xx/min, xx/h.
Press “Enter” to confirm and save the selection.
A conversion factor can be entered as a substitute for a not available mass flow unit as described in the after-
following chapter 7.2.5.8, “Factor volume flow QV programmable unit” on page 65. In this case the unity xx is
selected into combination with the desired time unit.
