Fct. Text Description and setting
3.05 USER UNIT Set any required unit for flowrate and counting
→ TEXT VOL. Set text for required flowrate unit (max. 5 characters)
Factory setting = Liter or US MGal
Characters which can be assigned to each place:
● A-Z, a-z, 0-9, or “ – “ (= blank character).
Press ↵ key to transfer to subfunction “FACT. VOL.”
→ FACT. VOL. Set conversion factor (F
M
) for volume
Factory setting ”1.00000 E+3” for ”Liter” or ”2.64172E-4” for ”US MGal”
(exponent notation, here 10³ or 2.64172 x 10 -4 )
Factor F
M
= volume per 1m³.
Setting range
● 1.00000 E-9 to 9.99999 E+9 (= 10 -9 to 10 +9 )
Press ↵ key to transfer to subfunction “TEXT TIME”.
→ TEXT TIME Set text for any time (max. 3 characters)
Factory setting = ”h” (hours)
Characters which can be assigned to each space:
● A-Z, a-z, 0-9, or “ – “ (= blank character).
Press ↵ key to transfer to subfunction “FACT. TIME”
→ FACT. TIME Set conversion factor (F
T
) for time
Factory setting ”3.60000 E+3” for ”h” (exponent notation, here 3.3 x 103).
Set factor F
T
in seconds.
Setting range
● 1.00000 E-9 to 9.99999 E+9 (= 10 -9 to 10 +9 )
Press ↵ key to return to Fct. 3.05 “USER UNIT”.
3.06 APPLICAT. Set modulation range of A/D converter
→ FLOW ● STEADY (150% of Q
100%
) ● PULSATING (1000% of Q
100%
)
Press ↵ key to change to subfunction ”EMPTY PIPE”.
EMPTY PIPE Empty pipe detection EPD (see Sect. 6.9)
● NO (Press ↵ key to change to subfunction “ADC Gain“)
● YES (Press ↵ key to change to “VAL. FULL“)
● VAL. FULL (Press ↵ key, precautinory query)
● CALIB. NO (Press ↵ key to change to “VAL. EMPTY“)
● CALIB. YES (Press ↵ key, calibration will start with flashing display “WAIT“,
duration approx. 20 seconds)
Make sure that measuring tube is completely filled!
● STORE NO (Press ↵ key to change to “VAL. EMPTY“)
● STORE YES (Press ↵ key to change to “VAL. EMPTY“)
● VAL. EMPTY (Press ↵ key, precautinory query)
● CALIB. NO (Press ↵ key to change to “VAL. EMPTY“)
● CALIB. YES (Press ↵ key, calibration will start with flashing display “WAIT“,
duration approx. 20 seconds)
Make sure that measuring tube is completely empty!
● STORE NO (Press ↵ key to change to subfunction
” ADC GAIN“)
● STORE YES (Press ↵ key to change to subfunction
“ADC GAIN“)
Please Note: The values of the measured impedances must be in range 0 - 150.
The difference of the value VAL. EMPTY must be
10 greater than the value of VAL. FULL!
→ ADC GAIN Set gain of A/D converter
● AUTO ● 10 ● 30 ● 100 Select with key ↑ or ↓
Press ↵ key to change to subfunction ”SPEC. FILT.”.
→ SPEC. FILT. Activate special filter for noise/interference suppression?
PLEASE NOTE information and examples given in Sect. 6.6.
● NO (Press ↵ key to change to Fct. 3.06 ”APPLICAT.”)
● YES (Press ↵ key to change to subfunction ”LIMIT VAL.”).
