Voltage Selection and Fuse Changing

The voltage setting and fuses of the analyzer can be changed to international
standards. To change the voltage setting or fuses:

WARNING:

Disconnect all power from the analyzer before proceeding.

1. The AC power module is located on the back panel of the analyzer

(see Figure 3-15). Directly above the power cord receptacle is the
voltage select/fuse panel. To remove the cover, insert the tip of a
small blade screwdriver into the notch above the power cord recep-
tacle (see Figure 3-12) and carefully pry the cover loose.

2. Remove the cover and the fuse block assembly.

3. Pull the voltage selector card straight out of the housing by pulling

on the indicator pin (see Figure 3-12).

4. Turn the card so that the desired voltage can be read at the bottom.

5. Slide the indicator pin around the card so that it is at the top of the

card when the voltage is read at the bottom (see Figure 3-13).

6. Place the voltage selector card back into the housing. The edge

where the desired voltage is printed should go in first and the printed
side of the card should be facing down.

7. Replace the fuse block and the cover. Verify that the indicator pin is

pointing to the correct voltage.
