For this purpose, a numerical value is displayed with a flashing digit. During the edit procedure the
function of the keys are:
lear: The whole value is reset to zero.
Next digit: The flashing moves to the next digit at right. f the rightmost digit is flashing,
the flashing moves to the leftmost digit.
Increment digit value: ncrements the value of the flashing digit by one. f the digit has
a value of 9 the value becomes 0.

4.3 Weighing parameters
Press key while “ PAr “ message is on display. Weighing parameters are edited one at a time.
Edit each value by using and keys; press to accept and proceed with the next
parameter. You may press and go back to the previous parameter while editing. When all the
paremeters are accepted, the device saves the changes automatically.The parameters are:
1. apacity 1
n single range instruments, this is the maximum capacity.
n multi (two) range instruments, this is the maximum capacity of the first
range (smaller range).
2. apacity 2
n single range instruments, this value have to be entered as 0 (zero).
n multi (two) range instruments, this is the maximum capacity of the
second range (greater range).
3. Scale interval (e)
This value is the difference between two consecutive indicated values (e).
n multi range instruments, this is the interval of the smaller range (e1). The
device selects e2 automatically.
( Accepted values: 1,2,5,10,20,50 )
4. Decimal places
This value determines the place of the decimal dot while indicating weight
values.
( Accepted values: 0,1,2,3 )
5. Stability range
Stability of equilibrium is said to be reached, when the rate of change in displayed weight values
falls below a predetermined rate. This predetermined rate depends on 'Stability range' (SR) and
'Stability delay' (SD). f the difference of the maximum and the minimum weight values
calculated in a preiod of SD is less than or equal to SR, stability condition is satisfied.
The range for displayed weight values, for determination of the stability.
( Accepted values: 0 .. 5 interval(s) )
Note: A value of zero means 0.5 interval

6. Stability delay
The time period for displayed weight values, for determination of the
stability.
( Accepted values: 1 .. 5 second(s) )
7. Filter
This value determines the interpretation of the changes in weight. A lower
value causes fast reactions to weight changes and is suitable in relatively
stable conditions. A higher value causes slow reactions but the vibrational
flickers are eliminated.
( Accepted values: 1 .. 5 )
8. Zero at power-on
This setting determines if the indication is set to zero automatically at
power on. (initial zero setting)
( Accepted values: 0 (off) , 1 (on) )

4.4 Adjustment ( alibration )
Press key while “ AyAr “ message is on display. There are 3 options for proceeding.
Dead load adjustment:
This option may be used when only dead load (zero point) adjustment is
needed.
While this message is displayed, unload the platform and press key
when there is no motion. The display will become blank until the device
calculates and saves the calibration data. After that, the device exits the
menu and returns to the weight display.
Span adjustment:
This option may be used when a dead load adjustment is not needed, but a
span adjustment is needed. (The device assumes the last zero point for a
reference for the adjustment weight.)
While this message is displayed, press key. The dead load
adjustment (zero calibration ) is skipped.
Enter (edit) the value of the weight which will be used for adjustment.
Accept with key.
The value you entered will be displayed constantly. Load the platform with
the adjustment weight you entered and press key when there is no
motion. The display will become blank until the device calculates and
saves the calibration data. After that, the device exits the menu and returns
to the weight display.
Full calibration: This option is performing the dead load adjustment and the span
calibration consecutively.
While this message is displayed, unload the platform and press key
when there is no motion. The display will become blank until the device
calculates and saves the calibration data.
Then Enter (edit) the value of the weight which will be used for calibration.
Accept with key.
The value you entered will be displayed constantly. Load the platform with
the calibration weight you entered and press key when there is no
motion. The display will become blank until the device calculates and
saves the adjustment data. After that, the device exits the menu and
returns to the weight display.

5 Operation
After applying power to a properly installed and configured device, the power-on tests are performed.
During these tests all the segments (indicating devices) on the display are turned on. After completition
of these tests the device performs initial zero setting, if configured. At the end, the weight display
appears.
The weight display is the primary display of the device. The measured weight values are displayed with
the unit of weight sign turned on (e.g. kg indicator). Other indicating devices which accompany the
weight value are explained in the introduction chapter of this manual.
5.1 Weighing with tare
n order to tare the weight on the platform, press the key. The indicated weight value is saved as
tare value and the indication switches to net mode. The “NET” symbol indicates this situation. To save
the weighing result and get a printout press the key. To cancel the tare and return to gross
weighing mode press the key again or unload the platform and press the key. Unstable and
negative weight values can not be tared.
5.2 High resolution display
This function needs the function key configured for high resolution display.
t is possible to temporarily display measured weight values in 10-fold increased resolution. To perform
this function press the key. The indicated weight value is displayed in high resolution for 5
seconds. At the end of this period, the indication returns to normal resolution mode automatically. t is
also possible to turn off high resolution mode by pressing the key without waiting for 5 seconds.
5.3 Multi range weighing
f the device is configured as a multi-range instrument, the range which is currently active is indicated
on the display by “R1” or “R2” indicators. Range selection from the smaller range (R1) to the greater
range (R2) is performed automatically when the indicated load exceeds the maximum capacity of the
smaller range. Range selection from the greater range (R2) to the smallest range (R1) is performed
automatically when indication is zero or at a negative net value equal to gross zero, or manually when
the key is pressed when there is no load. Tare is cancelled automatically.
