2.3.5 Proforma™ 300OEMi Initial Probe Setup
MTI recommends a dedicated probe holder which is machined from a material that has a low
coefficient of thermal expansion (such as Invar). MTI also recommends using the split cylinder
approach to clamping the probes. The standard “D” style push-pull probe used with the
Proforma™ 300OEMi has a diameter of 14.86±.0.03 (0.585±0.001”) and a length of 33.78±0.3
(1.33±0.01”). The end user must also account for the two exiting cables from the probe which
have a minimum bend radius of 18mm (0.7”). The probe holders should guarantee that the
probes can be positioned diametrically opposed to each other. Mount the probes in the probe
holder such that the witness line on the first probe is aligned to the witness mark on the second
probe.

As an initial setting, mount the probes so that they are approximately at the maximum standoff
distance from the measured surface. Note that the initial probe adjustment will be finalized with
the system running. Route the probe wires such that they do not come in contact with, nor run
parallel to any other electrical wires or field sources.
