SensorLink's Troubleman's Kit is reviewed by lineman Aaron (Bob's Decline): the radio AmpStick (≈69 kV, 1–5,000 A auto-range) and VoltStick (≤37 kV, ±1 V) with adapters and a wireless receiver. Field trials at 69 kV/12.47 kV substations produced readings ≈283–303 A and demonstrated ease of ground-level checks, with occasional wireless-range and clamp-fit issues.
