Integral Operational Health Monitor JCI 133
Additional circuits within JCI 131 fieldmeter to provide voltage modulation of shield around fieldmeter sensing head for continuous monitoring of instrument performance without interference to normal instrument operation. Output signals show operational health status.
Support Pole JCI 137
For mounting JCI 131 fieldmeter about 2m above local ground surface looking upwards. The support includes a separate base that can be driven into the ground, a 2m stainless steel tube with flange for JCI 131 mounting and an aperture at the base for the connecting cable to pass from inside the pole back to a monitoring base station. A flange ring near the top of the tube provides a ring of holes for securing stabilizing guy lines
