Use t h e f o l l o w i n g p r o c e d u r e s f o r m e a s u r i n g v o l t a g e between two p o i n t s , peak t o peak
v o l t a g e , e t c .
1) A p p l y a s i g n a l to the INPUT t e r m i n a l , and a d j u s t the VOLTS/DIV and SWEEP TIME/DIV
c o n t r o l s . Reset the t r i g g e r point i f n e c e s s a r y .
Set the AC-GND-DC c o n t r o l to AC.
2) Use the y POSITION c o n t r o l so t h a t one of the p o i n t s to be measured f a l l s on one of
the h o r i z o n t a l g r a d u a t i o n l i n e s , w h i l e the other p o i n t can s t i l l be observed on the CRT
s c r e e n .
3) Use the POSITION c o n t r o l so t h a t the p o i n t to be measured f a l l s on the v e r t i c a l
s c a l e a t the c e n t e r of the CRT.
4 ) Measure t h e v e r t i c a l d i s t a n c e between the two p o i n t s . M u l t i p l y t h a t v a l u e by t h e

When t h e 10:1 probe i s used, a l s o m u l t i p l y the v a l u e by t h e a t t e n u a t i o n r a t e of the
