Dual Range Tester – R18 

 

In this example a low voltage (35VDC) 470uF electrolytic capacitor is connected to the test leads and the 
pattern achieved is markedly different depending on the switch setting. See the photos of actual screen 
shots; 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At times the oscilloscope controls may need altering to get the desired pattern shape and size, but often 
use of the High Low switch will negate this need to alter the ‘scope settings.
