Requirements
When
the 3468A
is calibrated,
careful
note
should
be taken
of the ambient
temperature.
In order to meet and maintain the specifications listed in Table 5-3,
the
3468A
should
be
operated
within
+
5°C
(+
9°F)
of the
calibration
temperature,
also called the reference temperature.
As it comes from the factory,
the 3468A
should
be operated
within
an ambient
temperature
range of 23°C
+5°C
(73°F
+9°F).
The
instrument
may
be
operated
within
an
ambient
temperature
range
of O°C
to 55°C
(+32°F
to 131°F)
but with
reduced
ac-
curacy.
WARNING
To prevent potential electrical or fire hazard, do not expose
the multimeter to rain or moisture.
Spe
ications
¢
The specifications for the 3468A are the performance characteristics of the instru-
ment which are certified. These specifications are listed in Table 5-3, and are the
performance standards or limits against which the multimeter is tested. Included in
the table are some supplemental characteristics of the 3468A and should be con-
sidered
as additional
and general information
for you, the user.
Because
of the
many operational capabilities of the 3468A,
exercise care when
checking the in-
strument specifications.
Any
changes
in the
specifications
due
to
manufacturing
changes,
design,
or
traceability
to the
National
Bureau
of Standards
will be covered
in a manual
change supplement.
