Description
HiTester 3174 Insulation Tester for Reliable Safety Testing
The HiTester 3174 Insulation Tester is designed to support dependable electrical safety testing in manufacturing, quality control, and maintenance environments. By combining insulation resistance testing and AC withstand voltage testing in a single instrument, it simplifies workflows while maintaining consistent measurement accuracy. Its low cost design makes it accessible without sacrificing performance or safety.
Contact Check Function
One of the key advantages of the HiTester 3174 Insulation Tester is its contact check functionality. This feature verifies proper connection to the device under test before applying high voltage, reducing the risk of incomplete tests and improving operator safety. When used with an additional high voltage test lead set, the contact check function enhances confidence in every measurement cycle.
Stable and Accurate Voltage Output
Unlike testers affected by fluctuations in input power, the HiTester 3174 Insulation Tester uses a PWM based voltage generation method to maintain precise test voltages. This stabilized output improves test reliability and ensures consistent results across varying power conditions. AC withstand testing supports voltages up to 5 kV with true RMS current detection for accurate leakage current measurement.
Flexible Test Management
The instrument allows users to store up to eight test conditions each for insulation resistance and withstand voltage testing. This capability supports fast setup changes and reduces operator error. Adjustable timers, ramp control, and delay functions allow smooth voltage transitions and controlled testing sequences tailored to different products and standards.
Automated and Remote Operation
When paired with Safety Test Data Management Software, the HiTester 3174 Insulation Tester supports full remote operation. Test results can be monitored, logged, and managed externally, making it suitable for automated production lines and traceability focused quality systems.
