7.0 Probe Shield Care and Replacement
If you have an HI-6122, HI-6022, HI-6105, HI-6005, or HI-4422 Field Probe, over
time the probe shields (the cone-shaped structures with axis labels) may
accumulate foreign materials that could become embedded in the shield surface.
Probe shields must be kept clean to maintain proper operation.
If the probe shields need to be replaced, you may order them from
ETS-Lindgren. Follow these steps to replace the probe shields:
1. Remove the nylon screws from the probe shield.
2. Lift the shield straight up and away from the housing.
Lift the shield high enough to clear the internal antenna assembly, or
you may damage the assembly. Never touch the antenna assembly.
You may transfer a static charge to the assembly that may distort or
disable the measuring capability in that axis.
3. With the probe in a protective, supportive position, carefully replace the
probe shield by lowering it straight down onto the housing.
Make sure to clear the internal antenna assembly when lowering the
shield or you may damage the assembly.
4. Replace the screws snugly without over-tightening them.
