They also supervise the process and use of TMDE to perform voltage, current, power, impedance, frequency, microwave, temperature, physical-dimensional, and optical measurements.
They perform these functions in a strictly controlled laboratory environment where the temperature and humidity are constantly monitored.
For example, the K3/K4 section would maintain Frequency counter, Oscilloscope, Synthesized Signal Generator and power sensor.
While K1/K8 would maintain digital multimeter, high voltage probe and resistance standards.
Lastly K5/K6 would deal with truck scales, pressure gauges, optics and micrometers.
