Attached to the instrument is a serial number sticker. The serial number is in the form OOOOAOOOOO. five digits are the suffix. The prefix is the same for all identical HP 54201A or HP 54201D instruments; the prefix only changes when a change is made to the instrument. The suffix, however, is assigned sequentially and is different for each instrument. The contents of this manual applies to instruments with serial number prefix(es) listed under SERIAL NUMBERS on the title page. The serial number is also displayed on the HP 54201 Peripherals menu is selected.

An instrument manufactured after the printing of this manual may have a serial number prefix not

listed on the title page. This unlisted serial prefix indicates the instrument is different from those described in this manual. The manual for this newer instrument is accompanied by a Manual Changes supplement. The supplement contains "change information" that explains

adapt the manual to the newer instrument.

In addition to change information, the supplement may contain information for correcting errors in

the manual. To keep this manual as current and accurate as possible, Hewlett-Packard

recommends that you periodically request the latest Manual Changes supplement. The

supplement is identified by the manual print date and part number, both of which appear on the

manual title page. Complimentary copies of this supplement are available on request.

is not properly set to match the input voitage.

2-4. Line Voltage Selection

Before turning ON the instrument verify that the Line Voltage Select Switch on the rear panel matches the input line voltage. The 6 Amp fuse installed satisfies both voltage settings of 115 and 230 VAC.

2-5. Power Cable

This instrument is equipped with a three-wire power cable. When connected to an appropriate AC power outlet, this cable grounds the instrument cabinet. The type of power cable plug shipped

with the instrument depends on the country of destination. See figure 2-1 for option numbers of

power cables and plug configurations available. Part numbers for each cable option are listed in the replaceable parts section of this manual.

2-6. OPERATING

ENVIRONMENT

The operating environment is noted in table 1-2. Note should be made of the non-condensing humidity limitation. Condensation within the instrument can cause poor operation or malfunction.

Protection should be provided against internal condensation.

The HP 54201A/D will operate to all specifications, within the temperature and humidity range given in table 1-2. However, reliability is enhanced by operating the instrument within the following ranges.

Recommended Temperature: +20 to +35° C (+68 to +95° F) Recommended Humidity: 20% to 80% non-condensing

High temperature/humidity combinations should be avoided.

2-7. CLEANING REQUIREMENTS

<:>

When cleaning the HP 54201A/D, CAUTION must be exercised on which cieaning agents are used. USE MILD SOAP AND WATER. If a harsh soap or solvent is used, the water-base paint finish

WILL BE damaged.

BE CAREFUL when cleaning the keyboard. Water can damage the keyboard circuitryifit seeps under the keys.

2-8. STORAGE AND SHIPMENT

2-9. Environment

The instrument may be stored or shipped in environments within the following limits:

Temperature: _40°C to

Humidity: Up to 90% at

Altitude:... Up to 15 300 metres (50 000 Feet)

,-75°C

65°C

The instrument should also be protected from temperature extremes which cause condensation

within the instrument. Condensation within the instrument may cause malfunction if the instrument is operated under these conditions.

2-10. Packaging

HP 54201A/D - Installation

2-11.

TAGGING FOR SERVICE. If the instrument is to be shipped to a Hewlett-Packard office for

service or repair, attach a tag showing owner (with address), complete instrument serial number, and a description of the service required.

2·12.

ORIGINAL PACKAGING. If the original packing material is not available or is unserviceable,

material identical to those used in factory packaging are available through Hewlett-Packard offices.

If the instrument is to be shipped to a Hewlett-Packard office for servicing, attach a tag showing

owner (with address), model number, complete instrument serial number, and a description of the service required. Mark the container FRAGILE to ensure careful handling. In any correspondence, refer to the instrument by model number and serial number.

2-13.

OTHER PACKAGING. The following general instructions should be used for repacking with

commercially available materials.

a. Wrap instrument in heavy paper or plastic. b. Use a strong shipping container. A double-wall carton made of 350 lb. test material is

adequate.

c. Use a layer of shock-absorbing material 70 to 100 mm (3 to 4 inch) thick around all sides of

the instrument to provide firm cushioning and prevent movement inside the container. Protect control panel with cardboard.

d. Seal Shipping container securely. e. Mark shipping container FRAGILE to ensure careful handling. f. In any correspondence, refer to instrument by model number and full serial number.

FUNCTIONAL VERIFICATION

The Self Tests, resident in ROM, are a series of tests that confirm proper function of the mainframe hardware and firmware. While the Self Tests provide the user with a confidence level of greater than 90%, they do

not

verify the critical specifications given in table 1-1 of Section 1. Perform the

Performance Tests for complete instrument compiiance to these critical specifications.

To execute the self tests, press the SYSTEM menu key, then press the NEXTjPREV key until the Test & Service menu is displayed as shown below. Using the Field arrow keys, move the biinking cursor

to the Execute Selftest field. Enter either 0, 1, or 2 and follow the instructions displayed on

screen. An audible beep will be heard when each self test has been completed. A failure of a seif test should be followed by resident SYSTEM

(in this order). The self tests snould then be re-selected to

check

calibration routines 0, 5, and 6

whether the self-calibration

routines corrected the error. Repeated failure of a self-test, or faiiure of a self-caiibration routine

may

dictate the need of a particular hardware adjustment.
