Voltage conversion
_ This instrument may be operated from either a 100 V to
240 V, 50/60 Hz power source. Use the following pro-
cedure
to
change

operation
or
vice
versa.
1. Replace fuse FS1 with a fuse of appropriate value, 0.3 A
slow-blow type for 100 VAC to 120 VAC operation,
0.2 A fast-blow for 220 VAC to 240 VAC operation.
2. Reinsert it for appropriate voltage range.
3. When performing the reinsertion of fuse holder for the
voltage conversion, the appropriate power cord should
be used. (See Fig. 1.)

CASE DISASSEMBLY AND ASSEMBLY
1. To open the case, turn the unit upside down with the
rubber feet facing’ up.: (See Fig: °2) pene nas
2. Remove the four screws:from the bottom tase.
3. Carefully separate the two halves of the case and
recalibrate the unit following the prescribed procedure.

4. To close the case, lower the bottom case and guide the
front and rear panels into thier slots. Position the rub-
ber feet as illustrated and screw the two halves of the
case together.
Do not overtighten screws.
100/120/220/240 VOLT CONVERSION
This instrument operates from a 100 V, 120 V, 220 V or
240 V AC, 50 to 60 Hz line-voitage source. The applied vol-
tage is indicated on the rear panel. To convert from the
specified voltage to other line voltages, replace the voltage
plug position on PC Board, referring to the figure below and
change the rear panel applied voltage indication. Also, be
sure to replace the fuse to correspond to the line voltage
0.3 A slow-blow fuse for 100 V to 120 V operation and
0.2 A fast-blow fuse for 220 V to 240 V operation. If it is
not wired to your local line voltage, set the power trans-
former wiring as shown below. (See Fig. 3.)
