1. Test of the devices – protection against leakage currents with a protective leakage current range 50 μA to 50 mA

The Hioki ST5540 leakage current meter improves a wide range of testing features compared to previous devices. Measure voltage drop across simulated impedance, switch power supply poles and do measurements under simulated single fault conditions in test equipment. The measurement range ranges from 50 μA to 50 mA, allowing equipment testing – protection against maximum leakage currents. Support user to calculate and display measured value in detail and accuracy.

The ST5540 includes simulated human body measurement networks and high frequency voltmeter, and is also capable of switching power supply poles and performing measurements under simulated single error conditions in been tested.

2. Measure True RMS voltage, range due to electricity in the range 100V to 250V

The Hioki ST5540 leakage current tester provides true-rms current measurement in a True-RMS circuit that accurately analyzes electrical components.

+ Voltage leakage to ground

+ 3 Types of contact lines

+ 7 types of detection current when the device is broken

Measure the current on the damaged device

4 types of leakage current, all equipment is damaged, measure the free current

+ 3 types of leakage current on the shell

Check the value with the corresponding frequency in the range of 50Hz – 60Hz. Current measurement: DC, AC (true rms, 0.1 Hz ~ 1 MHz), AC + DC (true rms, 0.1 Hz ~ MHz), AC (15 Hz ~ 1 MHz). Accuracy:

+ DC measurement: ± 2.0% rdg. ± 6 dgt. (typ.)

AC / AC + DC measurement: ± 2.0% rdg. ± 6 dgt. (15 Hz to 100 kHz, typ.)

AC peak voltage measurement: ± 2.0% rdg. ± 6 dgt. (15 Hz to 10 kHz, typ.)

Allowing users to perform a variety of measurements, enhancing the working capacity of the Hioki ST5540 for different test-testing requirements.

3.Sensor clamp design supports 20A measuring range measurement

The ST5540 leakage current meter measures better with a sensor clamp design that has a rating of up to 20A. Increased terminal protection, minimizing risk of overvoltage. When measuring leakage currents, it is easy to generate errors from the inputs. This will affect the accuracy of the results when measuring. In the medical field, in particular, deviation of a few amps can have serious consequences. Hioki ST5540 has been designed to meet stringent electrical safety standards, with high precision measurement. The device meets the stringent requirements on medical device power measurement. Especially for devices in direct contact with the patient, the most precise is required.
