CHOICE OF INPUT COUPLING
Press the
‘MODE’
button repeatedly until the
‘INPUT’
settings appear.
A short activation of the
'Up'
button will switch
between ac
(2)
or dc
(1)
input coupling.
When measuring the
”ripple”
of a DC
voltage : put the input on AC to limit the
measurement to the AC component of the
signal.
Note:
•
At time bases of 1s/div and slower, the
input coupling is DC-only.
SET THE INPUT REFERENCE
Keeping the 'Up' button pressed for a
longer
time
will internally connect the input to ground
and will keep the current readout as zero
reference for dc measurements.
