Calibration

CAUTION
The outer shells of the front panel terminals (OUTPUT,
SYNC OUT, TRIG IN, SCLK IN, 10M REF IN) are
connected to the instrument’s chassis and therefore to
the safety ground.
CAUTION
Do not attempt to float the OUTPUT from ground as it
may damage the 5251 and other equipment connected
to the 5251 I/O connectors.
Calibration
The recommended calibration interval is two years. Calibration
should be performed by qualified personnel only.
Abnormal
Conditions
Operate the 5251 only as intended by the manufacturer. If you
suspect the 5251 has been impaired, remove it from the PXI
chassis and secure against any unintended operation. The 5251
protection is likely to be impaired if, for example, the instrument
fails to perform the intended measurements or shows visible
damage.
WARNING
Any use of the 5251 in a manner not specified by the
manufacturer may impair the protection provided by
the instrument
