B–1

Appendix B: User Service

This section contains instructions for user and preventive mainte-

nance. If the instrument is not functioning properly, it should be

referred to qualified service personnel or returned to Tektronix for

service. Packaging directions for shipment are on page 1–9.

Fuse Replacement

The WFM 90 and WFM 91 do not have any user replaceable fuses.

Battery Replacement

Instructions for installing or replacing the batteries along with battery

operation tips are listed starting on page 1–12.

Cleaning

The instrument should be cleaned often enough to prevent dust and

dirt from accumulating.

CAUTION. Instrument Cleaning

Do not allow water to get inside the instrument. Do not clean any

plastic materials with benzene, toluene, xylene, acetone, or similar

compounds, because they may damage the plastic.

Exterior

Clean the dust from the outside of the instrument with a soft, clean

cloth or small brush. A brush is especially useful for removing dust

from around the keypad buttons and the connectors. Hardened dirt

can be removed using a soft cloth dampened with a mild detergent

and water solution. Abrasive cleaners should not be used.
