Voltage Laboratory has developed high accuracy capability to support national voltage activities. The chart illustrates the traceability for voltage measurement in Malaysia.

The traceability of DC voltage standard to SI unit is realised by using Josephson Junction Voltage system in the range of 1 V, 1.018 V and 10 V with best uncertainty at 0.2 mV.

Photometry and Radiometry Laboratory has developed high accuracy system to support national illuminance scale. Illuminance scale is one of the fundamentals in the realisation of candela in optical radiation. The chart illustrates the traceability for illuminance parameter measurement in Malaysia. 

Measurement  range is start from 10 to 1000 lux with expanded uncertainty 1.1 %

RF power and scattering parameter or S-parameter are the quantity associated with microwave measurements where the services are offered by the laboratory to support national RF and microwave measurements activities. Measurement frequency capability starts from the range of 10 MHz up to 18 GHz. The measurements are limited to Type N and PC7 connectors. The estimated uncertainties for RF power and S-parameter are described as follows:

NMIM’s Time and Frequency laboratory maintains two high performance and three standard performance Caesium (Cs) atomic reference frequency standards. One of the high performance Cs reference frequency standards is designated as Malaysian National Frequency Standards (MNFS), with accuracy of ± 5 × 10-13 s .

 With these standards and continuous All-in-View GPS time comparisons, where the data is contributed to Bureau Weights and Measures (BIPM) for the generation of the International Atomic Time (TAT) scale. NMIM is capable to provide traceability to the SI Unit of time interval for time and frequency measurement.

 Malaysian Standard Time (MST) is UTC (NMLS) + 8 Hours, due to the time zone selected which is the longitude of 1200 East. UTC (NMLS) is currently defined to be the epoch of the 1 pulse per second timing signal output at the rear panel of the Malaysian National Frequency Standards. NMIM steers the frequency of the standard to maintain UTC(NMLS) to be within approximately 1 ms of the Coordinated Universal Time (UTC).
