For the manual adjustment procedure according to the two cases described the following remarks have to be
taken into account:
• After manual adjustment the flow-scale of the indicator is no longer valid.
• The display will only indicate in % of the new flow range.
• Switching of units is impossible.
• The indicator can be always resetted to the original adjustment according to manufacturers
calibration at any time.
• The given procedures will only adjust the current output and the display to the new measuring
range for a different fluid and/or new process conditions.
• The result of this adjustment is NOT a calibration! If proof of the new adjustment is requested a
real calibration by comparison to a standard has to be made after adjustment!
• The following interactions with other functions apply:
Interaction with other functions:
Action Function Effect
1. Setting of manual adjustment values F52 -5... Manual adjustment table is overwritten
2. Activating of manual adjustment table F51 -2 - Manual adjustment table active
- %-indication only
- Totalizer does not count
- No other flow rate unit selectable
- Function F64 for option /A2 has no effect,
with manual adjustment
3. Deactivating of manual adjustment
table
F51 -1 - Standard adjustment table active
- F11 is set to flow rate
- Flow unit is the same as before activating
manual adjustment
- Totalizer value is the same as before
activating manual adjustment
Due to the limitations described it is strongly recommended to order a new scale and EEPROM from
manufacturer (this gives a real new flow scale without new calibration) or to order a new calibration by
the manufacturer together with a new scale and EEPROM for the new fluid and/or new process conditions
(this gives new adjustment plus new calibration).
