TEMP. ENG. UNIT (318)
Selection
Select the unit for the temperature measured value.
See also PCB TEMPERATURE (Page 117) and SENSOR TEMP. (Page 123).
Options:
• °C
• °F
• K
• R
Factory setting:
°C
LOW FLOW CUT-OFF (442)
Selection
Switches "low flow cut-off" function on and off.
In the lower measuring range, small flow quantities (creepages) can lead to large
measured value fluctuations. Switching on this function stops these flow quantities from
being recorded.
See also SET. L. FL. CUT-OFF.
Options:
• Off
• On
Factory setting:
Off
SET. L. FL. CUT-OFF (323)
Entry
Enter switch-off point of low flow cut-off.
The hysteresis between the switch-on point and the switch-off point is always 1 % of the
end flow value.
See also LOW FLOW CUT-OFF.
Prerequisite:
• LOW FLOW CUT-OFF = on
Input range:
Switch-off point: 0...50 % of end flow value (
MAX. FLOW).
P01-PMD7xxxx-05-xx-xx-xx-000
Factory setting:
5 % (of end flow value)
SET LRV (637)
Entry
Depending on the setting in the LINEAR/SQROOT parameter (
Page 113), enter a flow
value or a pressure value for the lower current value (4 mA) here.
• LINEAR/SQROOT = Flow (square root) (factory setting)
flow value
• LINEAR/SQROOT = Differential pres.
pressure value
Factory setting:
0
