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 True RMS values on large, crystal-clear display n 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 Low Battery Indicator i:i»mi...

3 ■ Ensures safe measurements in the cubicle (F Point 2 Point 1 Easily measure right through cable insulation Safely measure around busbars Also safe for metallic conductors Long grip for better safety Safely measure 380-480 V AC lines ■ Get accurate measurements easily The HiTESTER measures the voltage between two probes. To ensure accurate measurements, apply the voltage detector probes perpendicular to the object to be measured. To measure voltage to ground, apply one probe to a ground conductor. Apply each voltage detector probe perpendicular to the object to be measured. Correct measurement...

4 □ HiTESTER 3258 measurement principle Measurements with traditional non-metallic-contact voltmeters and phase detectors dpend on the coupling capacitance (Cj and C2) between voltage detector electrodes in the probe tips and the measurement objects. That voltage detection method can present problems due to the dependence of the coupling capacitance on the material properties of the measurement objects, making accurate voltage determination (Vm = Vm2 - Vmj) problematic. The SAFETY HiTESTER 3258 employs a new technological principle to detect accurate measurement voltage (Vm) independent of coupling...
