Led n° 1 : Center of zero or range1 if multirange is set
Led n° 2 : Steady weight or range2 if multirange is set.
Net Led : Net weight
5SETUP MENU
It is possibile to entry in “CONST” and “CALIB” menu functions, only with jumper JP1 closed
In order to enter in Menu Setup, turn on the indicator with JP1 closed or turn on the indicatore
keeping pressed the SET key ( in this case it is not possibile to reach the “CONST” and “CALIB”
functions )
Display Description
CONST Scale setup parameter ( Capacity , Division , range )
CALIB Weight calibration
PARAM Scale setup parameter submenu

5.1 MENU CONST
Display Description
CAPAC Rated capacity in kg
DIVIS Division value ( Select option from 0,001 to 50 )
RANGE Set Multirange ON or OFF ( Two fields of 3000 div. each one )
On the basis of the rated capacity, automatically will be set also the autozero value ( 10% of
the rated output ), the value of the zero track and the value of the zero key ( 2% of the rated
output )
If the RANGE option is set to ON, the weight range will be splitted in two fields of 3000
divisions each one; if the weight on the display is in range n° 1 , the led 1 is turned on, while,
when the weight is in the second filed, the led 2 is turned on. The passing from field 1 to field
2 with the change of the division is automatic, but the passing from field 2 to field 1 will have
effect only with scale unloaded.
If it is set a number of division upper than 6000 it is not possible to set RANGE to ON.
6WEIGHT CALIBRATION
After the confirmation of the CALIB function, the display will show alternatively the weight
value and the “CAL” indication.
6.1 ZERO CALIBRATION
Press the key 0 The display will be set to Zero.
A long pression of the 0 key will cancel the zero. Calibration
6.2 SPAN CALIBRATION
Press the key SET The display will show all zero with one digit blinking; enter the
correspinding value of the weight to be used for the span calibration; place the weight on the
platform of the scale and confirm with SET.
Press ESC to end the procedure.

9BATTER SETUP MENU
Display Description
STDBY Time in minute after that the display will be set in standby status ( If = 0 standby
not active )
STATO If set to ON it means that the indicator is connected to battery so it is possible to
display the status of the battery charge.
During the standby status, the scale is not turned off; to return to normal weight indication,
press a key or move the plate of the scale.
In order to display the status of the battery charge, press the ESC key. The indication is a
value from 0 to 5; the maximum value of charge is 6,2 V corresponding to 5.
If the charge of the battery is lower than a safe value, the display will show the indication
“BATT” and after a time, it will automatically turned off.
10 HIGH PRECISION WEIGHT DISPLA
The high precision corresponding value of the current weight will be indicated on the display.
Press ESC to exit.
