RMS was established in 2004 and appointed as the ONLY Fluke authorised service centre in South Africa.  Les Wesson, who started with Fluke South Africa in the early 1980s, has since transformed the company into a Level 2 BBBEE business with 51% shares held by historically disadvantaged groups. RMS is a totally autonomous service company, running as an independent, third-party electrical test and measurement equipment service centre. The company prides itself in the local support, both in repair and calibration, of not only Fluke and Megger instruments, for which it is an authorised service centre, but also equipment manufactured by most other manufacturers.

RMS prides itself on its SANAS-accredited scope of measurement capabilities since they are accredited for the smallest uncertainties in a few parameters in South Africa, outside of the National Metrology Institute of South Africa (NMISA). Calibrations are performed according to the manufacturer's performance verification procedures wherever possible, and it is standard practice for the instrument's performance to be checked for compliance with the manufacturer's accuracy specifications. If found to be outside these performance limits, adjustments are performed, and the 'as found' and 'as left' results are reported on the calibration certificate. This enables the customer to take remedial action if required, which may result from an instrument being found to have been performing outside the manufacturer's accuracy specifications. At the end of each calibration, a calibration certificate is issued, which bears the SANAS accreditation logo. This provides not only local recognition that the RMS calibration technology has met and continues to meet the requirements of ISO IEC 17025, as proven through independent third-party assessment by SANAS, but also international recognition of calibration performed in South Africa. This is of particular importance if a company has overseas principals and needs to comply with international standards.

Our Time and Frequency laboratory uses a Global Navigation Satellite System (GNSS) to obtain traceability without the need to send the standards for calibration. We use a single GNSS receiver, frequency counter and oscillator method.  This method tracks the time difference between the GNSS receiver and oscillator (laboratory rubidium frequency standard); the obtained data is compared to the reference values provided by the National Metrology Institute of South Africa (NMISA) to determine the relative drift.

Our laboratory holds accreditation for performing calibrations both on-site and in-house across various parameters, such as:
 

• In Frequency Calibration, we cover the calibration of frequency sources and frequency meters up to 2 GHz.

• Calibration of time interval source and time interval meters: namely period source, rise/fall time, and stopwatches.

• Calibration of rotational speed: namely contact and non-contact tachometers, centrifuges, and other rotational devices.

• Phase angle and oscilloscopes are part of our electrical DCLF accreditation.
