Safe Voltage Measurement in Breaker Cubicles. Hioki's new HiTester enhances voltage measurement safety. Development of the Safety HiTester 3258 opens the door to a new realm of safety by accurately measuring non-destructively through wire insulation, a particular safety concern t o those who maintain and inspect electrical facilities. The HiTester measures the voltage between two probes. To ensure accurate measurements, apply the voltage detector probes perpendicular to the object to be measured.
