5. Connect the
probe
ground clip to
a reference point
( usually
a ground
or test
point ) and
connect
the
probe tip to
the
unknown
voltage to be
measured .
If the readout displays the message " OUCH ” ( input
voltage
equals or
exceeds 500
V ) ,
immediately
disconnect the test leads from the unit - under - test to
prevent possible instrument damage .

3. Read the dc voltage on the readout .
CH1 AC RMS
voltage measurements
are
influenced
above 1 KHz
by probe
compensation when
a X10
probe is
used .
See
"
Probe
Compensation " in
Section
3 to
ensure
best
results .
Below
100
Hz
the CH

coupling
time

degrades

ments . Use
of a 10X probe
increases this time
con
stant and
extends
the
useful range
to 20 Hz .

are

mea
surements
made
thru

Channel 1 Volts
u
The 2236 has the capability to measure the dc and true
ac coupled rms values of the input signal through CH 1 OR
X & DMM connector . Maximum voltage measurement when
using either a 1x probe or cable is 49.99 V ( dc or ac rms ) .
Maximum voltage measurement with a 10X probe is 499.9
V dc and 349.9 V rms ac . When an overrange condition
exists the readout will display the message “ OUCH " . The
procedure
for
measuring
voltage
through
the CH
1 OR X
&
DMM input
connector
is as
follows :
