CAUTIONS ON OPERATION

1. UNKNOWN (MEASUREMENT) TERMINALS

Do NOT

NOTNOT

NOT apply DC voltage or current to the UNKNOWN terminals. Doing so will damage

the 4284A. Before you measure a capacitor, be sure the capacitor is fully discharged.

2. MEMORY CARD

Use Agilent Technologies-specified memory cards containing 4284A-specific data only. If

other memory cards are used, the 4284A may be damaged. Non 4284A-specific data

contained on a memory card is not guaranteed, and data may be lost.

To insert a memory card into the MEMORY

MEMORYMEMORY

MEMORY card slot, hold the memory card with the label

facing upward and with the contacts at the slot opening･Insert the card into the slot until

it "clicks" in place.

To remove a memory card from the 4284A, press the UNLOCK button and remove the

card.

Do NOT remove a memory card while LOADing or STORing data. Doing so may damage

the memory card and any data stored in the memory card may be lost.

Store memory cards in their furnished card cases when not in use. The card case protects

memory cards from contamination and electrostatic discharge.

Also, store memory cards under the following environmental conditions.

Storage Temperature Range: -30 ℃to +70 ℃

Storage Humidity Range: 30%. to 85%. (@ +50 ℃)

Do NOT shock or stress memory cards.

When storing or moving your 4284A, be sure the memory card slot is empty (no memory

card inserted).

Do NOT touch the connector contact surface of a memory card and do NOT use chemical

liquids to clean the contacts.

Two replacement fuses are furnished with the 4284A option 201. Additional fuses are

available from Agilent Technologies. Order PN 2110-0046.

Fuse: Mpm Time Delay 0.5A 12.5V

If you need this fuse, contact your nearest Agilent Technologies Sales and Service Office.

To replace A32F1 , perform the following procedure.

2. Remove A32F1 (indicated in Figure A) from socket and carefully insert the new fuse.

3. Replace the handler interface board, top shield plate, rear feet, and top cover.

If the handler interface continues not to output +5V after A32F1 has been replaced,

contact the nearest Agilent Technologies office.
