USER MANUAL

6.MAINTENENCE

The following instructions are executed by qualified personnel only. To avoid

electrical shock, do not perform any servicing other than the operating

instructions unless you are qualified to do so.

6-1.Fuse Replacement

If the fuse blows, the power lamp indicators will not light and the

oscilloscope will not start. The fuse should not normally open unless a

problem has developed in the unit. Try to determine and correct the cause

of the blown fuse and replace only with a fuse of the correct rating and type

on the rear panel.

WARNING. For continued fire protection. Replace fuse

only with 250V fuse of the specified type and rating, and

disconnect power cord before replacing fuse.

6-2.Line Voltage Conversion

The primary winding of the power transformer is tapped to permit operation

from 100, 120, or 230VAC 50/60Hz line voltage. Conversion from one line

voltage to another is done by changing the line voltage selector switch as

shown in page 7. The rear panel identifies the line voltage to which the unit

was factory set. To convert to a different line voltage, perform the

following procedure:

(1).Make sure the pow

er cord is unplugged.

(2).Adjust the line voltage selector switch to the desired line voltage

position.

(3).A change in line voltage may also require a corresponding change of

fuse value. Install the correct fuse value as listed on rear panel.

6-3.Cleaning

To clean the oscilloscope, use a soft cloth dampened in a solution of mild

detergent and water. Do not spray cleaner directly onto the oscilloscope

because it may leak into the cabinet and cause damage.

Do not use chemicals containing benzine, benzene, toluene, xylene,

acetone, or similar solvents. Do not use abrasive cleaners on any portion

of the oscilloscope.
