FUNCTION LEVEL
f.fvnc
F Key function
–
Makes possible to define the F
key function. Available functions:
oFF
- Key not used.
kold
- Hold PV
RSt
- Resets Maximum and Minimum values
PkoLd
- Peak Hold
XI
- Displays maximum
LO
- Displays minimum
ZERO
- Automatic zero
These functions are described in item 5.
Dig.in
Digital Input Function
- Makes possible to define
the digital input function. Functions available are the
same as the ones available for the
F
key, except for
the Zero function, replaced by the Tare function.
oFF - kold - rSt - PkoL -–XI - LO -
tare
These functions are described in item 5.
filtr
Input Digital Filter
- Used to reduce the noise in the
measured value. Adjustable from 0 to 60. 0 means
the filter is off and 60 means maximum filtering. The
filter slows down the response of the measured
value.
ofset
Displayed offset
- Added value to the measured
value to correct the offset. Expressed in the unit
configured input type.
En A.z
Enables Auto zero
– Enables the auto-zero function
of the indication. The indication will turn to zero if the
input value is within the programmed range in
A.Zran
for 3 seconds.
Auto-zero occurs when the indication is relatively
stable. It is used to eliminate the influence of
interference or
small
deviations in the zero of a scale.
A.Z.rAn
Maximum level for zero
– Maximum level of the
scale zero deviation, where auto-zero is activated.
This value can be programmed up to 2% of the end of
scale.
Bavd
Communication Baud-Rate
- Transmission baud
rate used in serial communication (RS-485) in
bps
and
kbps
.
1200, 2400, 4800, 9600, 19200, 38400, 57600,
115.2. (NONE parity) 1.2P, 2.4P, 4.8P, 9.6P, 19.2P,
38.4P, 57.6P e 115.2P (with EVEN parity).
Adres
Communication Address
- A number that identifies
the instrument in a communication network.
CONFIGURATION LEVEL
In.typ
Input Type
- Selects the input signal or sensor type
to be connected to the PV terminals. Refer to
Table
1
for options.
Changing the input type causes all other parameters
related to PV and alarms to be changed as well,
therefore, this parameter shall be the first to be set.
Dp.pos
Decimal Point Position
- Determines the position of
the decimal point in the display.
scale
Parameter that defines the limits of indication of
entries.
0
– Configurable indication from – 31000 to +
31000.
1
– Configurable indication from 0 to + 60000.
2
– Configurable indication from 0 to +120000,
showing only even values.
The PV values, SP Alarms and Offset also obey
these limits.
In.lol
Input Low Limit
- Determines the minimum limit for
input signals. The band created can be ascending or
descending characteristic in relation to the input
signal behavior.
In.kil
Input High Limit
- Determines the maximum limit
for input signals. The band created can be
ascending or descending characteristic in relation to
the input signal behavior.
Ovt.ty
Analog Output Type
- Allows selecting the type of
signal available on the analog output: 0-20 mA or 4-
20 mA.
ov.lol
Output Low Limit
Low Limit for analog retransmission
–
Determines the display value corresponding to an
electric current of 4 mA (or 0 mA).
0v.kil
Output High Limit
High Limit for analog retransmission
- Defines
the PV value that results in a 20 mA analog output
current.
Ovt.er
Output error
Error signaling for 4-20mA output -
Configure the
state of the analog output when an error occurs in
the retransmission (beginning or end of the scale).
CUSTOMIZED LINEARIZATION LEVEL
Inp.01
Inp.30
Defines the extreme points of the customized
linearization. Values must be in the input signal unit.
Ovt.01
Ovt.30
Defines the proportional indications in respect to
each segment of the customized linearization.
Values are in the intended indication unit.
CALIBRATION LEVEL
All input and output types are factory calibrated, and we recommend
not making any calibration procedure. This level should only be
accessed by experienced personnel.
If this level is accidentally accessed do not touch the
or
keys, go through all the screens until you return to operating cycle
(operation).
In..lo(
Zero Input Calibration -
It allows you to calibrate
the offset of PV. You can increment or decrement
the desired value tapping the keys
and
.
In.ki(
Span Input Calibration -
Sets the gain of PV.
Ov.lo(
Zero Calibration for the Analog Output -
Value for
the analog output offset (0 or 4 mA).
Ov.Ki(
Analog Output Span Calibration
– Value for gain
calibration of the analog output (20mA).
k.type
Hardware Type
- Parameter to adjust the indicator
to the type of available hardware. Should not be
changed by the user, except when a new accessory
is inserted or removed.

AUTOMATIC CALIBRATION LEVEL
Specific calibration for weighing systems, where the user himself
performs the calibration of their system, using two reference weights,
minimum and maximum, and setting their indication values.
To access this cycle press and keep pressed
and
for 30
seconds.
