2-3 ENVIRONMENTAL REQUIREMENTS 

Your Accuris  balance  is  a  precision  instrument,  and  requires  an  environment 

which  is  free  from  excessive  air  flow,  dust,  corrosive  elements,  vibration  and 
temperature or humidity extremes. An unsuitable environment will adversely affect 
the performance of your balance.

 

 

The area and environment where your balance is used should be kept clean 
and dry all time;

 

 

The optimal operating temperature is 20

 (68

℉)

 and 50% relative humidity;

 

 

Always use a stable AC power source that meets the input specifications of 
the AC/DC power adapter. 

 

 

Do not situate the balance:  

o

 

In direct sunshine; 

o

 

Next to windows or doors where there can be excessive air movement 
or rapid temperature fluctuations; 

o

 

Near a heater or air conditioner; 

o

 

Near vibrating, rotating or reciprocating equipment; 

o

 

Near a magnetic field or equipment that generates a magnetic field; 

o

 

On an unstable surface; 

o

 

In areas where there are corrosive vapors; 

 

2-4 SETTING UP YOUR BALANCE

 

CAUTION:  

Always allow the balance to warm up in its ambient 

environment for 2 hours prior to use. 

If the balance is moved from a cold environment to a warmer 

environment, keep the balance in a sealed bag during the warm up time. 

This will prevent condensation from forming on the internal components 

and external surfaces of the balance. 

 

1.

 

Place the balance on a stable and level surface;

 

2.

 

Level the balance by turning the adjusting feet, checking the level 

indicator on the balance, until the bubble appears in the center of the 

circle;

 

3.

 

Carefully  place  the  pan  support  and  the  pan  into  position  on  the 

weighing mechanism.  These parts should be carefully put into place, 

no downward force is required; 

4.

 

Plug the AC  adaptor  in to a suitable electrical outlet and into the 

back of the balance.
