5.4 Accumulation. 
5.4.1 normal accumulate counting 

before do accumulation operate, please set unit weight, then load partial 
samples, quantity window will show current counts, after 

 

indicator on

, press 

  key, quantity windows will show current total weight (TOTAL indicator 

on) for 3 second, then return to normal count mode. 
Please note, before you stare next accumulate, scale must return to zero. 

 
 

5.4.2  Accumulation mode 

When in normal count mode, press 

  key, scale will enter accumulation 

mode. Weight window will show current count value, unit weight will show new 
total weight, quantity window show current total weight (TOTAL indicator 
flash). 

In accumulation mode, after add sample and 

O

 indicator on, press 

  key, 

quantity window will show total count. 

 
 

5. 5    Limit set and Comparing 
5.5.1 Limit Set 

Before use this function, pleas sure limit function must be set enable ( see 
detail in parameter setting table), you can set either one point or two points 
limit. 

Press

  key. 

Li-LO 

appear at Weighing display, and low limit value shows 

that currently set at UNIT.W display, enter low limit value with numerical keys, 

press 

  key. Low limit set, and a beep will sound to sign. Then 

Li-HI 

appears at Weighing display, and high limit value shows that currently set at 
UNIT.W display, then advance to the high limit, enter high limit value with 

numerical keys, press 

  key. High limit set, and a beep will sound to sign. 

High limit set, and go back to working area.
