Adams AQT SERIES User Manual

 

•  Calibration may be required when the balance is initially installed or 

if the balance is moved from a location.      

 

•  With time and use, mechanical deviations may occur.  Therefore 

calibrate the balance whenever the best accuracy is required or 
when any deviation is observed during weighing a test weight.    

 

•  Before calibrating it is necessary to have the proper calibration 

weights.  The weights should be known to an accuracy that is 
appropriate for the balance being calibrated, for example, OIML 
Class M1 type or ASTM E617 Class 4.  If you do not have proper 
weights do not attempt calibration.

•  Before entering calibration mode, press [On/Off] to turn the power 

on for 1 minute. 

• Press [On/Off] to turn the power off.  

• Press [Unit] first and then press [On/Off], while keeping the [Unit] 

key pressed. The display will show the A/D value.  Then press [Unit] 
and the display will show the last calibration value used, press [Tare] 
to choose either 100g or 200g.  

•  Wait for the stable indicator to be displayed,  

• Press [Unit]  - the display will show “L 100" or “L 200”, with the "L" 

flashing.  

Place the appropriate weight on the platform.  A beep will be heard 
after a few seconds and the display will show the weights value.    

• Press [On/Off], to turn off the power.  

• Press [On/Off] to turn on the power again. Place maximum weight 

(200g) on the platform to verify weighing is correct. If not, repeat the 
calibration.
