also in the weighing mode. If the entered value is confirmed, it will substitute the one in the set-up environment.
PROCEDURE
1) Place the empty container on the scale and press TARE to tare it.
2) Check that the zero is on the display and press MODE.
3) The display suggests a percentage; the possible options are: 100.0, 200.0, 5.0, 10.0, 20.0, 30.0, 40.0, 50.0, 60.0, 75.0.
4) Press “ZERO” or “TARE” several times to reach the desired sample size.
5) Put the reference weight on the scale and press ENTER/PRINT to confirm or C to cancel the operation and return to
weighing.
6) Press ENTER/PRINT; the display will show “SAMPL”. After a few instants the display will show the selected percentage
put on the platform.
7) Add the quantity to be measured on the scale and the value will appear on the display.
8) By pressing the MODE key one switches from the display of the percentage to the display of the net weight and vice
versa.
9) To carry out a new sampling, press at length the MODE key and repeat the operations as describe in point 3).
“Er.Mot” ERROR DUE TO WEIGHT INSTABILITY DURING THE SAMPLING
It may happen that during the sampling phase the weight is unstable; the “Er.Mot” is shown remaining for about three
seconds. One should therefore repeat the sampling operation.
MINIMUM WEIGHT OF THE SAMPLE
It is necessary to use a net weight greater than 0.
VARIABLE PERCENTAGE QUANTITY (only for 17-key indicator)
It is possible to insert directly by keyboard any percentage, different from the ones proposed by the MODE key:
- With the scale at zero, after having stored a tare, press “F”+ “5”; the display will indicate “n S" and then "0" or a
quantity already stored.
- Modify and/or enter the quantity (max 3000.0) using the numeric keys.
- Follow the operations describe in point 5) in the PROCEDURE section.
PRINTING
If the presence of a printer has been configured, each time ENTER/PRINT is pressed, while either weight or percentage are
displayed, one prints the data programmed in the SEtuP >> SEriAL >> CoM.Prn >> Pr.ConF of the set-up environment
(TECH.MAN.REF.); for example:
- GROSS weight
- TARE weight
- NET weight
- Percentage quantity on the scale in that moment.
NOTE: If the sampling has not been made, the quantity percentile is not printed.
11.10 SINGLE SCALE REPEATER (rEPE)
The system is made up of one or more indicators (named REPEATERS) which receive the data of the display or of the
weight from another indicator or from a PC/PLC (named TRANSMITTER) and which therefore act as repeaters.
In the REPEATERS once this functioning mode has been set, one should configure the "rEPE.6", “rEPE.dC”,”Pr1577” or
"W.rEPE" parameter in the communication mode of the PC serial port (SEtuP >> SEriAL >> CoM.PC step
(TECH.MAN.REF.).
For further configuration and functioning details refer to the technical manual (SEtuP >> SEriAL >> CoM.PC step and
section "SERIAL PORT TRANSMISSION MODES", TECH.MAN.REF.).
If "rEPE.6", “rEPE.dC” or “Pr1577” communication protocol has been set in the REPEATER, one will need to set the
"rEPE.6" communication protocol in the TRANSMITTER on the desired port.
If "W.rEPE" communication protocol has been set in the REPEATER, one will need to set the protocol of the continuous
weight transmission on the desired port of the TRANSMITTER.
For further configuration details refer to the technical manual of the connected indicator.
