5.3 Other modes
Linear
V2H0 = 0
This mode is selected when the Silometer FMC 671 Z/676 Z transmitter is to revert to
measurement of level after being used for volume measurement.
• If the volume is proportional to level, e.g. standing cylinder, a volume
measurement is obtained by entering the »empty« and »full« volumes at
V0H1 and V0H2 respectively, see Section 4.3.
Step Matrix Entry Significance
1 V2H0 0 Select linear characteristic
2 - »E« Press »E« to activate linearization
Factory characteristic
V2H0 = 2
Use this option if your tank dimensions were sent to Endress+Hauser for the production
of a customer specific linearization table.
• You can check whether a factory linearization is stored in the Silometer
FMC 671 Z/676 Z transmitter by viewing matrix position V2H6:
- A number means a factory linearization is stored.
- A »0« means there is no factory linearization.
• The measurement units are those agreed on with Endress+Hauser.
Step Matrix Entry Significance
1 V9H5 e.g. 672 Reset transmitter, see Section 4.1 (default = operating mode 1)
- Enter probe constants at V3H5 and V3H6
2 V0H1/V0H2 - Calibrate as described in Section 4.2
3 V2H0 2 Select factory linearization table
4 - »E« Press »E« to activate linearization
Cancel current setting
V2H0 = 4
Use this option if you wish to enter an entirely new manual characteristic without a
transmitter reset. All values in the linearization table are cancelled and can be entered
anew.
Step Matrix Entry Significance
1 V2H0 4 Cancel all previous entries in the manual linearization table
2 - »E« Press E to register
Note!
• The function does not affect the horizontal cylinder characteristic or any factory
characteristic stored in the transmitter.
