• Select a probe with the correct measurement range• On aluminum and non-ferrous bases look for
probes with automatic ‘conductivity compensation’– Much less sensitive to differences in base

– Much less sensitive to part shape• Select the probe tip to meet the job.
– Wide tip or dual tip probes on rough surfaces
