measurement:
WARNING
The
following
procedure
uses
hazardous
voltages

when encountering
these lethal
voltage
levels.
L
While
in standby,
configure
the Model
236/237
to
measure volts by
setting
it to
source
OnA
on
the
inA
current
source
range.
2.
While
in standby,
set
the
Model 343A
calibrator to
output 0V
on the 10V
range.
3,
On
the
Model 236/237,
set
voltage
compliance
to
L1V
on the
1.1V
measurement
range.
4.
Place
the
calibrator
and
the
Model 236/237
in
oper-
ate.
5.
Verify
that
the
measured
voltage
reading
on the
Model
236/237
is
within
the
allowable
limits
listed
in the
Erst
entry
of
Table
1-5.
6.
On

reading
is
within
the
limits
