Connect the two probes then start adjusting.
A1⚪ = Channel A 1X compensation
A2⚫ = Channel A 10X compensation
B1⚪ = Channel B 1X compensation
B2⚫ = Channel B 10X compensation
ʅ --- Falling edge

>TH Positive Pulse width Greater than trigger*
*For Pulse width trigger, use T1, T2 cursor.
There are 4 Parameter displays on the bottom side of the screen.
I divided them into 2 groups, According to the parameters and channels.
1)⬅️Left side (Channel A and B only)

Vmin
Vp-p
Vrms - Root Mean Square Value
Vavg
ΔV ---- Difference between V1 and V2 cursors
Vtrg
Vbat - Battery voltage
2)➡️Right side (All Channels)
TwH --- Positive Pulse width time
TwL --- Negative Pulse width time
Cycl
Frqn
Duty
ΔT ---- Difference between T1 and T2 cursors
