Model 4145A
SECTION II
INSTALLATION
Z-l. INTRODUCTION
SECTION II
WARNING
2-2. This section provides installation instruc-
tions for the Model 4145A Semiconductor
Parameter Analyzer. This section also includes
information on initial inspection and damage
claims, preparation for using the 4145A, and
packaging, storage, and shipment.
IF THE INSTRUMENT IS TO BE
ENERGIZED VIA AN EXTERNAL
AUTOTRANSFORMER UNIT FOR
VOLTAGE REDUCTION, BE SURE
THAT THE COMMON TERMINAL IS
CONNECTED TO THE NEUTRAL
POLE OF THE POWER SUPPLY.
2-3. INITIAL INSPECTION
2-8. Line Voltage and Fuse Selection
2-4. The 4145A Semiconductor
Parameter
Analyzer, as shipped from the factory, meets all
the specifications listed in Table l-l. Upon
receipt,
inspect the shipping container for
damage. If the shipping container or cushioning
material is damaged, it should be kept until the
contents of the shipment have been checked for
completeness and the instrument has been
checked mechanically and electrically. The
contents of the shipment should be as shown in
Figure l-l. The procedures for checking the
general electrical operation are given in Section
III (Paragraph
3-10 SELF ,,,TEST) and the
procedures for checking the 4145A Semicon-
ductor Parameter Analyzer
against
its
specifications are given in Section IV. First, do
the self test. If the 4145A is electrically
questionable, then do the Performance Tests to
determine whether the 4145A has failed or not.
If the contents are incomplete, if there is
mechanical damage or defects (scratches, dents,
broken switches, etc.), or if the performance
does not meet the self test or performance tests,
notify the nearest Hewlett-Packard office (see
list at back of this manual). The HP office will
arrange for repair or replacement without
waiting for claim settlement.
2-5. PREPARATION FOR USE
CAUTION
BEFORE TURNING THE 4145A LINE
SWITCH TO ON, VERIFY THAT THE
INSTRUMENT IS SET TO THE
VOLTAGE OF THE POWER TO BE
SUPPLIED.
2-9. Figure 2-l provides instructions for line
voltage and fuse selection.
The line voltage
selection switch and the proper fuse are factory
installed for 100 or 120 volts ac operation.
CAUTION
USE PROPER FUSE FOR LINE
VOLTAGE SELECTED.
CAUTION
MAKE SURE THAT ONLY FUSES
FOR THE
REQUIRED RATED
CURRENT AND OF THE SPECIFIED
TYPE ARE USED FOR RE-
PLACEMENT. THE
USE OF
MENDED FUSES AND THE
SHORT-CIRCUITING OF
FUSE-
HOLDERS MUST BE AVOIDED.
2-6. POWER REQUIREMENTS
2-10. LINE FREQUENCY FILTER
2-7. The 4145A requires a power source of 100,
120, 220 Volts ac +lO%, or 240 Volts ac +5%-lo%,
48 to 66Hz single phase; power consumption is
270VA maximum.
2-11. To reject the effects of line-frequency
noise, set the FILTER switch on the rear panel
to the frequency of the ac power source.
