QR Code Link App 
 
The QR Code Link app displays QR codes for 
commonly used websites relating to the GDS-
200/300. The GW Instek webpage is included 
as an example. 
To use the QR Code Link app, download a QR 
code reader app for your smartphone and read 
the QR codes from the QR Code Link app. 
Resistance Calculator  
 
The resistance calculator can calculate the value 
of a resistor based on the band code. The 
calculator can also calculate the resistance of 
SMD resistors based on the 3/4 digit SMD 
code, EIA-96 (1%) or 2/5/10% code.  
See page 177 for information on the various 
resistor codes.
