3258 field measuring instruments safety hitester safely measure voltage breaker panels applicability optimized for 30-600 v ac new technology measure voltage on insulated electric cables measurable electrical cable: 38 mm 2 or larger insulated wires (100 mm 2 or larger recommended) safety measure safely around metal busbars and terminals cat iv 600v
2 hioki's new technology 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 to those who maintain and inspect electrical facilities voltage detector easy operation and informative display 2. measured value when the display has stabilized, the hold lamp lights and the measured value is displayed. 1. hot line check the hold lamp ? ashes when an energized line (at least 30 v ac) is detected. hot line indicator 3. hold measured value press the hold button to temporarily freeze the displayed value. lamp turns off measured value measurement hold size: 38 mm 2 or larger insulated electric line (100 mm 2 or larger recommended) 38 mm 2 (11.5 mm dia.) insulated cable 100 mm 2 (17 mm dia.) insulated cable actual-size cross sections applicable electric cable types safe probe heads reliably safe, non-metallic resin heads low battery indicator data hold indicator shows when data is being held (hold button pressed) aps indicator (auto power shutoff) the hitester automatically shuts off when 10 minutes have elapsed from the last operation (can be disabled) ac indicator voltage unit indicator measured value true rms values retain accuracy despite waveform distortion true rms values on large, crystal-clear display power button safety barrier
