3)Vernier T1 a nd T2 can be used to m eas ure t he ti me differ enc e bet wee n any two points;

2. Ap plication Cas es:

Case 1. Measure si mpl e sig nal s

Observe a cer tai n unk now n sig nal, rapidly s how a nd me asu re it s frequency an d pea k val ue.

Operating s tep s:

1)Connect th e bot tom l ine , and c onnect the pro be of C han nel A (or C han nel B) to the meas ure d point of the ci rcu it;

2)Set Channel A (or C han nel B) as “AUTO” m ode a nd “DC” coupling, a dju st (h ori zontal) time scale and (ve rti cal ) vol tag e scale to prese nt a cl ear s ign al di splay;

3)Adjust “Vt rg” t o pre sen t sta ble signal dis pla y;

4)Select mea sur ing d ata , suc h as Vpp (peak-t o-p eak v olt age ), Vavg ( ave rag e vol tage), FRQ (frequenc y), e tc.

Case 3. Use a Vernier t o mea sur e sig nal

Vernier can be used t o rap idl y mea sure waveforms in t erm s of ti me an d voltage.

A.Measure th e per iod o f the t hird peak of signal s our ce Operating s tep s:

1)Roll Encoder B to m ove c urs or to p osition O (T1) ;

2)Roll Encoder A to pla ce Ver nie r T1 to the sec ond p eak o f the s ign al;

3)Roll Encoder B to m ove c urs or to t he position P (T 2);

4)Roll Encoder A to pla ce Ver nie r T2 to the thi rd pe ak of t he si gnal; Conclusio n: △T=50uS is the p eri od of t he th ird p eak.

B. Measure th e pea k-t o-p eak v oltage of sign al so urc e Operating s tep s:

1)Roll Encoder B to m ove c urs or to p osition L (V1);

2)Roll Encoder A to pla ce Ver nie r V1 to t he peak of signal;

3)Roll Encoder B to m ove c urs or to p osition M (V2) ;

4)Roll Encoder A to pla ce Ver nie r V2 to t he trough of signal; Con clu sio n: △V= 3.2 0V is the peak-t o-p eak voltage of si gna l.

Case 4. Wa veform Comparis on
