Page 2-16 Warning

Change the procedure 1 and warning as follows:

1. Disconnect the 4284A’s power cord and allow 1 minute for the internal supply filter capacitors to discharge.

Dangerous energy/voltage exists when the 4284A is in operation,and for a time after it is powered down. Allow 1 minute for the internal capacitors to discharge.

Page 2-16

Add the following CAUTION after the procedure 7.

The interface board contains electronic components that can be damaged by static electricity through electrostatic discharge(ESD).To prevent ESD damage,maintain frequent contact with any bare sheet metal surface on the chassis. A grounding wrist strap (or similar device) is useful for this purpose. Handle the board car efully at all times. Avoid touching electronic components or circuit paths.

When used with the 42851A Precision Q Adapter, make the following changes: Two system messages are added.

"Warning, Cannot find resonance" (when the tuning capacitor cannot resonate with the DUT) "Waiting for trigger" (when the 4285A is not triggered)

On the Q CORRECTION page, the SHORT correction function is always set to ON. On the Q CORRECTION page, the Q-MODE field is added to select between EFFECTIVE Q mode and CIRCUIT Q mode.

NOTE

CAUTIONS ON OPERATION

1. UNKNOWN (MEASUREMENT) TERMINA LS

Do NOT

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

NOTNOT

the 4285A. Before you measure a capacitor, be sure the capacitor is fully discharged.

2. MEMORY CARD

Use Agilent Technologies-specified memory cards containing 4285A-specific data only. If other memory cards are used, the 4285A may be damaged. Non 4285A-specific data contained on a memory card is not guaranteed, and data may be lost.

To insert a memory card into the MEMORY 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 4285A, press the UNLOCK button and remove the card.

Do NOT remove a memory card while LOADing or STORing d ata. 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 ℃)

MEMORY card slot, hold the memory card with the label

MEMORYMEMORY

Do NOT shock or stress memory cards. When storing or moving your 4285A, 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.

3. HANDLER INTERFACE BOARD (0PTION 201)

If the +5V internal voltage output

output , a fuse on the handler interface board (A32F1) has blown and must be replaced.

outputoutput Two replacement fuses are furnished with the 4285A 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 S ales and S e rv ice O f f ice.

To replace A32F1 , perform the following procedure.

1. To remove the handler interface board (A32), perform proc edu re I th roug h 7

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.

The 4285A with an Option 002 accessory control interface

bias current source

, and an 42842C bias current test xture can apply

a 0 to 10A DC current bias to the device under test (

, an 42841A

). So

,high

current biased impedance measurement of coils and transformers can

be performed easily

, quickly

, and safely

.

The 4285A with Option 002 accessory control interface and the

resonant measurement method and an automated tuning operation.
