Note
and
record the voltage measured on
the
Digital Voltmeter. Reading should be 2.8867V
±O,0477V.

Cable length between the 3314A and the
Digital Voltmeter
should be as short as
possible.
Equipment Required:
AC/DC
Digital Voltmeter
3V Thermal
Converter
E. Calibrate the 3314A by pressing the Blue Shift Key
followed by
the
"RCL"
Key.
NOTE
F, Note
and
record the voltage measured on the
Digital
Voltmeter.
Reading
should
be 3.535V
±O.0477V.
G. Repeat step E.
For accurate test results, allow the 3314A
and the Thermal Converter time to settle and
adjust
to surrounding temperatures. A void
sudden temperature changes around the
Thermal Converter.
H.
Change
the
function on the 3314A to a Square
wave.
Procedures:
A. Preset the 3314A.
I. Note
and
record
the
voltage measured on the
Digital Voltmeter. Reading should
be
5.0V ± O.0477V.
