1. Turn off the instrument and disconnect the electrical cord.
2. Remove the high voltage plate from the instrument and place it on a fl at work surface.
3. Using needle-nose pliers, carefully remove the rectifi er from the capacitor.
4. Using a 5/16” nut driver, remove the 6-32 nut from the ground post and discard the nut.
5. Remove the rectifi er from the ground post and discard the rectifi er.
6. Using scissors, cut out the template on page 4 of these instructions.
7. Position the template on the instrument base as shown in Figure 1. Using the template, mark the location for the
two .1065” diameter screw holes.
8. Drill the two .1065” diameter holes where marked.
9. Use the 6-32 tap to make threads in the .1065” diameter holes.
10. Using a vacuum cleaner or suitable source of compressed air, removed all shavings from the instrument. Shavings
can cause arcing and extensive damage to the instrument.
11. Place the high voltage rectifi er on the instrument base, oriented with the tab with the large opening positioned
toward the capacitor.
12. Align the mounting slots of the rectifi er with the two 6-32 threaded holes in the instrument base and secure the
rectifi er using two 6-32 tefl on coated phillips head screws (399019) as shown in Figure 2.
13. Locate the wire with the blue ring terminal supplied with the retrofi t kit. Connect the ring terminal end of the wire to
the ground post and secure it with the new 6-32 nut (BR198126) as shown in Figure 3.
14. Route the wire as shown in Figure 4 and connect the insulated female end to the tab with the large opening of the
rectifi er.
15. Using the remaining wire from the retrofi t kit, connect the non-insulated end to the tab on the capacitor where the
previous rectifi er was connected (see Figure 3).
16. Route the wire as shown in Figure 4 and connect the insulated female end of the wire to the tab with the small
opening of the rectifi er.
17. Install the high voltage plate into the instrument.
18. Perform a power test to ensure that microwaves are being produced.
