Repair strategy

Probe tip, amplifier microcircuit, and regulator assembly
The probe tip and amplifier microcircuit are easily replaced. The regulator
assembly (A1) repair can be performed at either assembly or component level.
Module exchange programs are not available for this product.
Main cable and plastic sleeve guide
The main cable includes the probe wand, the main cable and the smaller power
supply cable. If the cable is damaged, both the cable and the probe wand
assembly must be replaced as a single unit. In this case, take the following parts
off of the old probe for use on the replacement probe:
– The nose assembly
– Nut
– Amplifier microcircuit
These items are shown in Figure 7-6, "Probe end disassembly" on page 66 and
Figure 7-7, "Probe wand components" on page 67
A kit is available that provides a preassembled main cable and probe wand. The
wand does not come with the amplifier microcircuit, nose-assembly, or tip,
because these may be easily removed from your old probe wand. Refer to
Table 6-2, "Replaceable parts" on page 52 for the part number of the kit.
