HP 3468A - Initial Inspection and Preparation

nitial Inspection
Your 3468A was carefully inspected before it left the factory. It should be free of
mars or scratches and in proper working order upon receipt. You should, however,
inspect the instrument for any damage that may have occurred in transit. 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 mechanically and electrically inspected. Procedures for checking the elec-
trical performance of the 3468A are given in the 3468A SERVICE MANUAL (-hp-
part number 03468-90001). If there is any mechanical damage or the contents
are incomplete, or the instrument does not pass its performance tests, notify the
nearest Hewlett-Packard office (a list of the -hp- Sales and Service Offices is
located in the back of this manual). If the shipping container is damaged, or the
cushioning material shows signs of stress, notify the carrier as well as the
Hewlett-Packard office. Save the shipping materials for the carrier.
Preparation for Use
Power Requirements
The 3468A Digital Multimeter requires a power source of 100, 120, 220, or 240
Vac (-10%, +5%), 48 Hz to 440 Hz single phase. Maximum power consump-
tion is 25 VA.
Line Voltage Selection
Refer to the rear panel of the 3468A for the line voltage option label. Make cer-
tain that the option marked on the label is the same as the nominal line voltage for
your area. Also check the left most switch (50/6Q0Hz switch) for the proper set-
ting, i.e., up for 50Hz and down for 6OHz. Table 5-2 lists the available power op-
tions.
