SECTION II
INSTALLATION
2-1 INITIAL INSPECTION
2-2 Before shipment, this instrument was inspected and
found to be free of mechanical and electrical defects. As
soon as the instrument is unpacked, inspect for any damage
that may have occurred in transit. Save all packing materials
until the inspection is completed. If damage is found, file
claim with carrier immediately. The Hewlett-Packard Sales
and Service office should be notified as soon as possible.
2-3 Mechanical Check
2-4 This check should confirm that there are no broken
knobs or connectors, that the cabinet and panel surfaces are
free of dents and scratches, and that the meter is not
scratched or cracked.
2-5 Electrical Check
2-6 The instrument should be checked against its elec¬
trical specifications. Section V includes an "in-cabinet"
performance check to verify proper instrument operation.
2-7 INSTALLATION DATA
2-8 The instrument is shipped ready for bench opera¬
tion. Before applying power to the instrument, see the
CAUTION notice in paragraph 3-11.
2-9 Location
2-10 This instrument is air cooled. Sufficient space
should be allotted so that a free flow of cooling air can
reach the rear of the instrument when it is in operation. It
should be used in an area where the ambient temperature
does not exceed 40°C (up to 55°C with derating).
