SECTION II
INSTALLATION
2-1. INITIAL INSPECTION
2-2. Mechanical Check
2-3. Check the shipping carton for evidence of
damage immediately after receipt. If there is any
visible damage to the carton, request the carrier’s
agent be present when the instrument is unpacked.
Inspect the instrument for physical damage such as
bent or broken parts and dents or scratches. If
damage is found refer to paragraph 2-6 for recom-
mended claim procedures. If the instrument
appears to be undamaged, perform the electrical
check (see paragraph 2-4). The packaging material
should be retained for possible future use.
2-4, Electrical Check
2-5. The electrical check consists of following the
performance test procedures listed in Section IV.
These procedures allow the operator to determine
that the instrument is, or is not, operating within
the specifications listed in Table 1-1. The initial
performance and accuracy of the instrument are
certified as stated on the inside front cover of this
manual. If the instrument does not operate as
specified, refer to paragraph 2-6 for the recom-
mended claim procedure.
2-6. CLAIMS FOR DAMAGE
2-7. If physical damage is found when the instru-
ment is unpacked, notify the carrier and the
nearest Hewlett-Packard Sales and Service office
immediately. The Sales and Service office will
arrange for repair or replacement without waiting
for a claim to be settled with the carrier.
2-8. The warranty statement for the instrument is
on the inside front cover of this manual. Contact
the nearest Sales and Service office for information
about warranty claims.
2-9. PREPARATION FOR USE
CAUTION
Before applying power, check the power
selector switch on the Tracking Generator
input power module (rear panel) for
proper position (115 or 230 volts).
2-10. Power Requirements
2-11. The Tracking Generator can be operated
from a 48- to 440-hertz input line that supplies
either 115- or 230-volt (+10% in each case) power.
Consumed power is normally less than 15 watts.
2-12. The 115/230 power selector switch on the
rear panel line power module must be set to agree
with the available line voltage. The selector switch
is located below the fuse holder and fuse extractor
lever. An arrow on the selector switch points to
callouts listing the line input voltage and fuse
amperage rating. To change the position of the
selector switch it is necessary to remove the power
cable, slide the protective cover to the left and lift
the fuse extractor before the switch can be
changed. With the fuse extractor extended, press
down and toward the desired direction. Replace
fuse with a fuse of the amperage rating for the
selected position. See Section VI for replacement
HP Part Numbers. The instrument is normally
shipped with fuse installed for 115-volt operation.
2-13. Power Cable
2-14. To protect operating personnel, the National
Electrical Manufacturers Association (NEMA) and
the International Electrotechnical Commission
(IEC) recommends that the instrument panel and
cabinet be grounded. The Tracking Generator is
equipped with a three-conductor power cable; the
third conductor is the ground conductor and when
the cable is plugged into an appropriate receptacle,
the instrument is grounded. To preserve the pro-
tection feature when operating the instrument
from a two-contact outlet, use a three-prong to
two-prong adapter and connect the green or green/
yellow lead on the adapter to ground.
2-15. Power cables are selected for shipment with
each instrument; with a line connector plug to
match the standard power cord for the country of
destination on the purchase order. A label indicat-
ing the power cable inside is affixed to the packing
case. Figure 2-1 indicates the connector plugs and
the HP part numbers for the various available
power cables and plugs.
2-16. OPERATING ENVIRONMENT
2-17. The Tracking Generator does not require
forced air cooling when operating at temperatures
from O to 55°C (32 to 131° F). When operating the
instrument, choose a location which will provide at
