EPD EXC. CURRENT Use this function to activate the empty pipe detection (EPD).
In the event of air pockets or if fluids are not homogeneous, the excitation current of the
measuring pipes increases. If the excitation current configured in this function is
overshot, error message #700 is output similar to the EPD LOW VALUE and EPD HIGH
VALUE functions.
User input:
5-digit floating-point number
Factory setting:
100 mA (deactivated)
! Note!
The function is not activated until a value under 100 mA is entered. The function is
deactivated if 100 mA is entered.
FIXED REFERENCE
DENSITY
In this function you can enter a fixed value for the reference density which is used to
calculate the corrected volume flow or corrected volume.
User input:
5-digit floating-point number
Factory setting:
1 kg/Nl
ZERO ADJUST. With this function you can automatically start zero point adjustment. The zero point
value determined by the measuring system in this way is applied to the function ZERO
POINT (see Page 57).
User input:
CANCEL
START
Factory setting:
CANCEL
" Caution!
Before carrying out the calibration, please refer to BA 057D/06/en “Promass 80
Operating Instructions” where a detailed description of the zero point adjustment is
given.
! Note!
• Programming is locked during zero point adjustment
and the display shows: “ZERO ADJUST RUNNING”.
• If the zero point adjustment is not possible, e.g. with a flow velocity
> 0.1 m/s, or has been canceled, then the alarm message “ZERO ADJUST NOT
POSSIBLE” is shown on the display.
• If the Promass 80 measuring electronics are fitted with a status input, then the zero
point can also be activated by using this input.
• After Zero point adjustment is completed, the new zero point can be called up with the
F key. If the F key is pressed again, you return to the ZERO ADJUST. function.
DENSITY SET POINT In this function, enter the density set value of the particular fluid for which you want to
carry out a field density adjustment.
User input:
5 digit floating-point number, incl. units (corresponding to 0.1...5.9999 kg/l)
Factory setting:
0 kg/l
! Note!
• The preset density entered here should not vary from the actual fluid density by a more
than ±10%.
• The appropriate unit is taken from the function group SYSTEM UNITS (see Page 8).
