22B4.2 Testing the Balance 
The amount of offset with respect to the reference weight can be checked. This is called “span test.” 
Performing a span test will not calibrate the balance. 
Use a weight for calibration that weighs 50% of the weighing capac
ity or heavier. To calibrate more 
accurately, use a weight that is equivalent to the weighing capacity. 
Please contact us if you wish inquire about or place an order for calibration weights.

The error is displayed. 
The display first indicates “dIFF” and then the weight error 
of the balance. 
A weight error is as follows: 
Weight error = True value – Current weight 
When a weight error is more than “0”, the displayed weight is 
less than the actual weight. 
Press any key to return to normal display.
