HIOKI 9267 PC Software for Electrical Safety Testers

• Control the ST5540/5541, 3153/3154/3156/3157, 3174, and other electrical safety measuring instruments from a computer
• Perform automatic insulation and dielectric strength (hipot) testing of up to 32 points with the High Voltage Scanner 3930
• Easily create and save insulation, dielectric strength, and continuity test records with a computer as required by the Electrical Appliance and Material Safety Act (Japan)

HIOKI 3159-02 Insulation/Withstand Tester

• Continuous testing of insulation (500/1000 V) and withstand voltage (500 VA transformer capacity)
• Insulation to withstand series test or withstand to insulation series test at auto mode, or individual test at manual mode
• Save up to 10 test settings each for the withstanding and insulation testing modes
• External I/O, RS-232C interface, Status output (relay contacts)

HIOKI ST9000 DISCHARGE DETECTION UPGRADE

• Option additional function for ST4030
• Detect microscopic partial discharges obscured by noise to determine defective insulation (pseudo-shorts)
• HIOKI original filter * (*Noise components within the high frequency components appearing within the entire response waveform are removed to extract only the partial discharge component in order to make a pass/fail determination. Jointly developed with Aisin AW Co., Ltd.)
• Peripheral equipment (antenna for discharge detection etc.) not required to easily detect discharge

HIOKI ST5520 Insulation Tester

• Rapidly assess in as fast as 50 ms
• Quick discharge of residual voltage
• Freely configurable test voltage (Set from 25 V to 1000 V, 1 V resolution)

HIOKI 3174 AC Automatic Insulation/Withstanding HiTester

• Continuous testing of insulation (500/1000 V) and withstand voltage (100 VA transformer capacity)
• Full remote operation when used in combination with the Safety Test Data Management Software 9267
• Save up to 8 test settings each for the withstanding and insulation testing modes
• Precise test voltage without power voltage dependency is generated using the PWM method

HIOKI ST5540/ST5541 Leak Current HiTester

• Compliance with Electrical Appliances and Materials Safety Act, JIS/IEC/UL standards
• Uninterrupted polarity switching function dramatically reduces cycle time
• Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards
