Step 2. Set up Static-Safe Workstation

Electrostatic discharge (ESD) can damage or destroy the input circuits of the HP 8702D. ESD can also damage or destroy electronic components that you are measuring. All work should be performed at a static-safe work station. The following figure shows an example of a static-safe work station (without the instrument) using two types of ESD protection:

• Conductive table-mat and wrist-strap combination.

• Conductive floor-mat and heel-strap combination.

1-5

Installing the HP 8702D

Step 2. Set up Static-Safe Workstation

Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat and wrist-strap combination provides adequate ESD protection when used alone.

To ensure user safety, the static-safe accessories must provide at least 1 MΩ of isolation from ground. Refer to Table 1-1 for information on ordering staticsafe accessories.

WARNING

These techniques for a static-safe work station should not be used when working on circuitry with a voltage potential greater than 500 volts.

Reducing ESD Damage

The following suggestions may help reduce ESD damage that occurs during testing and servicing operations.

• Personnel should be grounded with a resistor-isolated wrist strap before removing any assembly from the unit.

• Be sure all instruments are properly earth-grounded to prevent a buildup of static charge.

Installing the HP 8702D

Step 14. Copy the EEPROM Disk

The HP 8702D is shipped from the factory with an EEPROM backup disk which is unique to each instrument. The backup disk contains a copy of correction constants which were stored in the instrument’s internal memory at the factory. If your HP 8702D should ever be damaged, these correction constants may need to be reinstalled from the disk. Use the following procedure to create a backup copy of the disk.

The disks can be ordered as HP 92192A (box of 10).

A default file “FILE0” is created. The file name appears in the upper left-hand corner of the display. The file type “ISTATE(E)” describes the file as an instrument-state with EEPROM backup.

Press softkey to rename the file “FILE0” to “N12345” where 12345 represents the last 5 digits of the instrument’s serial number. (The first character in the file name must be a letter.) When finished, press

Label the disk with the serial number of the instrument and the words “EEPROM Backup Disk”.

Whenever the HP 8702D is returned to Hewlett-Packard for servicing and/or calibration, the EEPROM backup disk should be returned with the HP 8702D. This will significantly reduce the instrument repair time. The EEPROM backup disk procedure is now complete.

WARNING

These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so.

The opening of covers or removal of parts is likely to expose dangerous voltages. Disconnect the instrument from all voltage sources while it is being opened.

The power cord is connected to internal capacitors that may remain live for five seconds after disconnecting the plug from its power supply.

1

Remove the instrument top cover. Using an 8 lb-inch torque wrench, verify that

all

semi-rigid cables connected to the sampler/mixer assemblies are tight. In addition tighten any loose screws on the sampler/mixer assemblies (A4/5/6) and the pulse generator assembly (A7).

2

Remove the instrument bottom cover. Refer to Figure 4-19. Verify that cables W1, W31 and W32 are tight.
