AC & Low Frequency

AC & Low Frequency Laboratory are capable to generate and measure DC to 10 MHz and beyond covering voltage, current, and resistance parameters to support national AC & Low Frequency measurement activities. The chart illustrates the traceability for AC & Low Frequency in Malaysia.

The highest standards are primary Thermal Converters and AC DC Shunts maintained by utilizing comparison method of AC-DC. Different comparison methods for accurate RMS value determination of AC Voltage and AC Current at low frequencies are traceable to the national standard of AC Voltage and Current. The frequency range is from 10 Hz to 1 MHz with best uncertainty of 5 uV/V.
