Safety Summary

The following general safety precautions must be observed during all phases of operation,

service, and repair of this instrument. Failure to comply with these precautions or with specic

WARNINGS

elsewhere in this manual may impair the protection provided by the equipment.

In addition it violates safety standards of design, manufacture, and intended use of the

instrument.

The Hewlett-Packard Company assumes no liability for the customer's failure to comply with

these requirements.

Note

HP 4286A is designed for use in INSTALLATION CATEGORY II according to IEC

61010-1 and POLLUTION DEGREE 1 according to IEC 61010-1 and IEC 60664-1.

HP 4286A is an INDOOR USE product.

Note

LEDs in HP 4286A are Class 1 in accordance with IEC60825-1.

CLASS 1 LED PRODUCT

Ground The Instrument

To avoid electric shock hazard, the instrument chassis and cabinet must be connected to a

safety earth ground by the supplied power cable with earth blade

.

DO NOT Operate In An Explosive Atmosphere

Do not operate the instrument in the presence of ammable gasses or fumes

. Operation of any

electrical instrument in such an environment constitutes a denite safety hazard.

Keep Away From Live Circuits

Operating personnel must not remove instrument covers. Component replacement and internal

adjustments must be made by qualied maintenance personnel. Do not replace components

with the power cable connected. Under certain conditions, dangerous voltages may exist even

with the power cable removed. To avoid injuries, always disconnect power and discharge

circuits before touching them.

DO NOT Service Or Adjust Alone

Do not attempt internal service or adjustment unless another person, capable of rendering rst

aid and resuscitation, is present.

DO NOT Substitute Parts Or Modify Instrument

Because of the danger of introducing additional hazards, do not install substitute parts

or perform unauthorized modications to the instrument. Return the instrument to a

Hewlett-Packard Sales and Service Oce for service and repair to ensure that safety features

are maintained.

iv

Dangerous Procedure Warnings

Warnings

, such as the example below, precede potentially dangerous procedures throughout

this manual. Instructions contained in the warnings must be followed.

Warning

Dangerous voltages, capable of causing death, are present in this

instrument. Use extreme caution when handling, testing, and adjusting

this instrument.

v

Warning

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 HP 4286A has been checked mechanically and electrically

of the shipment should be as listed in T

mechanical damage or defect, or if the HP 4286A does not pass the power-on selftests

Power Cable

In accordance with international safety standards, this instrument is equipped with a

three-wire power cable. When connected to an appropriate ac power outlet, this cable grounds

the instrument frame. The type of power cable shipped with each instrument depends on the

country of destination. Refer to Figure 2-2 for the part numbers of the power cables available.

Warning

For protection from electrical shock, the power cable ground must not be

defeated.

The power plug must be plugged into an outlet that provides a protective

earth ground connection.

2. Turn the two type-N connectors to tighten the connection.

2-8 Installation and Set Up Guide

Connecting the Test Head

When you connect or replace the test head, turn o the HP 4286A.

1.

Place the test xture stand on a level surface. At this time, make sure that the

hexagonal hole on top of the stand is located in front of the two mounting posts as you look

at the stand. Then, lay the stand on its side.

2.

Allow the test head to pass under the xture stand from the side opposite to yours.

3.

Position the test head such that the connectors of the test head and holes on top of the

xture stand are aligned.

4.

Slightly tighten the two screws on the bottom surface of the xture stand to ensure

that the test head is suciently stable. Press screws to check for correct engagement of

their thread.

5.

Further tighten the screws while holding the test head with your hand to completely

secure the head in place.

6.

Place the xture stand with its bottom surface down.

Connecting the Test Head with L-type Coaxial Adapter

(Option 022 only)

When you connect or replace the test head, turn o the HP 4286A.

1.

Connect Connecting L-type Coaxial Adapter to the Test Head.

2.

Place the test xture stand on a level surface. At this time, make sure that the

hexagonal hole on top of the stand is located in front of the two mounting posts as you look

at the stand. Then, lay the stand on its side

.

3.

Allow the test head to pass under the xture stand from the side opposite to yours.

4.

Position the test head such that the connectors of the L-type Coaxial adapter and holes

on top of the xture stand are aligned.

5.

Slightly tighten the two screws on the bottom surface of the xture stand to ensure

that the test head is suciently stable. Press screws to check for correct engagement of

their thread.

Installation and Set Up Guide 2-9

6.

Further tighten the screws while holding the test head with your hand to completely

secure the head in place.

7.

Place the xture stand with its bottom surface down.

Connecting the APC-3.5 to 7mm Adapter

1. Check that the connector sleeve is fully extended.

2. Connect APC-3.5 to 7mm adapter to the test head connector through the hole on top of the

xture stand.

3. Tighten the adapter nut to secure this adapter in place.

2-10 Installation and Set Up Guide

Connecting a Keyboard (Option 1C2 Only)

When Option 1C2 is installed, an HP-HIL keyboard can be connected to the HP-HIL connector

on the rear panel of the HP 4286A. The HP-HIL keyboard provides an easier way to enter

characters for the le names, display titles, and Instrument BASIC programs. It can also access

the HP 4286A softkey functions by using keyboard function keys.For more information on the

HP-HIL keyboard, see the

HP Instrument BASIC User's Handbook Supplement

that is included

in Option 1C2.

Basic Measurement Procedures

This chapter provides a quick start guide of the HP 4286A. New users can quickly become

familiar with the HP 4286A by following these procedures. In this chapter, to help you learn

how to use the HP 4286A, impedance of inductors are measured as examples.

At the end of the quick start procedures, you will have learned how to get the following

measurement results:

Calibration

Setting electrical length of test xture

Correction of test xture

Basic Measurement Procedures 3-3

1. Power ON

Verify the connector box and the test head are correctly set up before turning ON the

HP 4286A. If they have not been set up, see Chapter 2.

Line Input Receptacle

ACPower cable is connected to this receptacle.

Figure 3-3. Line Input Receptacle and Fuse

Fuse

Use the following fuse:

HP Part Number : 2110-0917

(UL/CSA type, Semi Time Lag, 6.3 A 250 V)

If you need this fuse, contact your nearest Hewlett-Packard Sales and Service Oce.

Steps to turn on the power

1. Verify the power line setting is correct before you turning ON the meter. If necessary, see

\Changing the Line Voltage Setting" in Appendix B.

2. Connect AC power cable to the line input receptacle.

3. Press the LINE switch.

After the power-on self-test (approximately 10 seconds), the installed options and the

connected test head information are displayed.

Note

Only option numbers 1C2 and 001 are displayed at power-on (if they are

installed). Other installed option numbers are listed on the rear panel.

A 30 minute-warm-up period is required to stabilize the HP 4286A after it has been turned ON.

This ensures the HP 4286A its specied measurement accuracy
