(Advanced users only) CALIBRATION

IMPORTANT: This scale was professionally factory calibrated. It usually does NOT need to be 
recalibrated before use. However advanced users who seek optimum accuracy may wish to 
calibrate the scale periodically to maintain perfect accuracy. 
 
Please recalibrate your scale if it gives inaccurate readings or shows an error message. Incorrect 
calibration can occur if you do not follow the steps exactly. 

You will need an accurate calibration weight to calibrate this scale. 

(PS7-700/800/1000 

uses 

a 500g weight: 

PS7-200/300 

uses a 200g weight). In emergency situations you can use coins or 

known-weight items as a temporary calibration 
 
weight (ie: 40 US Nickels= 200g. 100 US Nickels = 500g) 

1) Turn the scale OFF and place it on a flat, very stable surface. 
 

2) Press 

 to turn on the scale and wait 5 seconds. 

3) Place the calibration weight(s) needed at the center of the tray, then wait 3 seconds. 

Note: The 

display may sometimes show 

 during calibration. please proceed to the next step.
