INSTALLATION & SET-UP 

- Choose a location that is free from the influences of the following: 

-

  Drafts: fans, heat/air duct, doorways or high traffic areas. 

-

  Vibrations. 

-

  Extreme temperature fluctuations: sunlight, ovens, or environments with 

wide ambient temperature changes. 

-

  Voltage Fluctuations. Do not share current with other Instruments that 

draw voltage in an inconsistent manner such as fluorescent lights, 
centrifuges and the like. 

- Place Instrument on a level, rigid surface. 
- Level the instrument. 
- Allow 30 minutes for warm-up. 
- Calibrate. All GP-Series are calibrated at the factory prior to shipment. 

Transportation of the instrument plus the differences in barometric pressure, 
humidity and ambient temperate conditions require calibration at the point of 
use.  Calibrate regularly, at least once a week, to ensure accurate weighing 
results. 

 

AC POWER CONNECTION & BATTERY OPERATION OPTION  

-  When  connecting  power  use  the  original  AC  adapter  supplied  with  the 

balance.    Using  an  unapproved  power  supply  may  damage  the  instrument 
and void the warranty. 

- Connect the plug to the instrument. 
-  Ensure  the  power  supply  is  compatible  with  your  instrument  AND  the  local 

line voltage. 

- Connect adapter to the power outlet. 
- Original Power Supply:  

  

Input:

    

 

 

 

110 -240 VAC, 50-60 Hz, 400mA 

  

Output:

  

 

 

 

9VDC, 300 mA 

  

Polarity:

  

 

 

 

Inside = 

-

, Outside = 

+

 

     

Battery Operation:  

  

6 AA 

 

Do not mix batteries.  Replace all six batteries at the same time. If the 
instrument will not be used for an extended period of time, remove all batteries 
from the instrument.  Failure to do so may cause leakage and damage to the 
instrument.
