9.0  OPERATIONS 
9.1 INITIALISATION 
 
When the balance is first switched on, it 
will display the balance serial number (if 
set), software revision, model capacity 
and then all segments on the display will 
be shown.  Overall the time taken is 
usually 5 -10 seconds. 
 
If an operator passcode has been set, the display will show “PASSCODE” and 
the main display will show a zero.  In this case you must enter the passcode 
to continue using the numeric entry method (see section 7.1). A different 
passcode may be set for a Supervisor to weigh or to have access to the 
selected User menus.   If the passcode has not been set the balance will 
continue as below. 
 
 
 
The display will show zero reading along 
with the zero symbol “Î0Í” and the 
weighing unit last used.  If automatic 
time calibration is enabled the balance 
will calibrate 15 minutes after power up 
or again after the pre-set time interval. 
 
9.2 PASSCODES 
 
If a passcode has been set to limit access to the weighing functions of the 
balance the display will show “PASSCODES” with the main digit set to zero.  
Use the numeric entry method (see section 7.1) to enter the code. The 
display will change to show 7 digits set to zero with the rightmost digit 
flashing. Make sure to enter the correct passcode to continue.  See the 
Section 13.6 for details.

18 CUSTOM Custom All As specified As specified 
 
It is possible to set the balance to display only grams.  Grams will always be 
one of the units enabled, by default.   
 
If “CUSTOM” unit is selected, the balance will prompt for entering a multiplier 
by displaying “MULTIPLIER XX,XXX”, where “XX,XXX” is the last stored \
value. Any value ranging from 0.100 to 10.000 may be entered, by which the 
weight in grams will be multiplied before being displayed. If a multiplier of 
greater than 1.000 is entered, the number of decimal places displayed will be 
reduced by one. This multiplier value will be saved for the next use till it is 
changed by the user. 
 
The balance displays the alternate weighing units with as much precision as 
possible.  For example, the 450g x 0.001g balance could weigh up to: 
 
Unit Maximum d =

9.4.1 Parts Counting 
 
This allows the user to weigh a sample of parts to compute an average un\
it 
weight and then determine the number of items being weighed by dividing the 
net weight by the unit weight value.  The result is always a whole number of 
parts. 
 
The balance will have a preset number of parts to be used as a sample. 
These values are 10, 25, 50 or 100 items. 
 
Steps: 
 
• Press [Mode] to show parts counting, “PARTS” will be displayed 
 
• Enter parts counting by pressing [Enter] 
 
• Press the [Up] or [Down] key to select the sample size, “REF QTY”,  
10, 25, 50, 100, etc., then press [Enter] to confirm 
 
• When “LOAD XX Pcs” is shown place XX number of items on the pan 
and press [Enter] to compute the average piece weight. Display will 
indicate the total weight in the last selected unit and then show “XX 
Pcs” sounding a beep. A message “PARTS” will be prompted on the top 
of the display to indicate that the balance is in the parts counting mode 
 
• Remove the sample and display will show “0 Pcs”.  
 
• Place an unknown quantity on the pan. The balance will then compute 
the number of parts based on the average piece weight. The display will 
show the result in Pcs 
 
• To count another item press [Mode] and continue as before 
 
• Checks will be made to determine that the weight of the reference parts 
is large enough for reasonably accurate counting (weight of each piece 
must be > 1d) 
 
• To return to normal weighing, press [Esc]

WT” and the sample weight in the last selected unit. After a while 
“100%” will be displayed. A message “PERCENT” will be prompted on 
the top of the display to indicate that the balance is in the percent 
weighing mode 
 
• Remove the sample and “PERCENT 0.00%” will be displayed 
 
• Place an unknown sample to display the percentage weight  
 
• To set another weight as 100%, press [Mode] and continue as before 
 
• To manually enter a value to be set as 100%, press [Up] or [Down] key 
when “PERCENT SAMPLE” is shown to select “PERCENT Ent Wt” 
 
• Press [Enter]. Display will show the value in the unit last used in the 
weighing mode 
 
• Enter the weight using the numeric entry method (see section 7.1).  
 
• Place unknown sample to display the percentage weight  
 
• To perform percent weighing with another sample press [Mode] and 
continue as before 
 
• To return to normal weighing, press [Esc]

9.4.3 Check Weighing 
 
During weighing of a sample the balance can be set to show if the weight is 
above or below an upper and a lower limit.  The display will use the arrows 
under the bar graph to show that check weighing is operating.   The bars 
between the arrows will indicate when the weight is below the lower limit, 
between the limits or above the upper limit. 
 
  
The buzzer can be set to be active when the weight is outside the limits\
 
(below the lower or above the upper) or within the limits (above the lower and 
below the upper limit), or turned off.  If desired, only one limit needs to be set. 
If only one limit is set the other limit is considered to be zero (lower) or the 
maximum (upper). 
 
The Check weighing is not active when the weight is less than 20d. This is 
the minimum weight at which the indicator bars are displayed and the buzzer 
sounds, if it is not set to OFF (see the next page). 
 
Steps: 
  
• Press [Mode] and then the [Up] or [Down] key to select Check 
Weighing.  When “CHECK” is displayed press the [Enter] key to enter 
Check Weighing mode 
 
• Press [Up] or [Down] to set the “LOW LIMIT” to “On” or “OFF” 
 
• Press [Enter] to proceed.  If the “LOW LIMIT” was set to “On” the 
display will show the current low limit in the unit last used in the 
weighing mode. You may change the limit using the numeric entry 
method (see section 7.1).  
 
• Press [Enter] to proceed 
 
• If the “LOW LIMIT” was set to “OFF” or the setting of the low limit is 
complete, then the display will change to “HIGH LIMIT”. Use [Up] and 
[Down] to set the “HIGH LIMIT” to “On” or “OFF”  
 
• Press [Enter] to proceed 
 
• If the “HIGH LIMIT” was set to “On”, the display will show the current 
high limit in the last selected unit which can be changed in the same 
way as in case of “LOW LIMIT” 
 
• Press [Enter] to proceed

stable and within the limit)     
“BUZZER Out”   (Beeper will sound when the weight on the pan is 
stable and outside the set limits) 
 
• Confirm the beeper setting by pressing [Enter] 
 
• When a weight is placed on the pan now, the display will indicate 
whether the weight is below the LOW LIMIT between the LOW and 
HIGH LIMITS or higher than the HIGH LIMIT using the capacity tracker,  
 
• To perform check weighing with another sample press [Mode] and 
continue as before 
  
• To return to normal weighing, press [Enter] 
 
9.4.4 Animal / Dynamic Weighing 
 
The balance can be set to weigh animals or moving items, also known as 
dynamic weighing. The balance will collect the weight over a period of time to 
arrive at an average value and display the value until the operator resets the 
balance. The actual weighing process can begin either automatically when 
the weight is placed on the pan or when initiated by the operator. The 
weighing unit can be selected as normal using the [Unit] and [Enter] keys, 
before entering the Animal / Dynamic Weighing process.
