Electrical and RF Standards Services
We currently provide calibration services for a range of industries, particularly aviation and electricity supply. We provide assistance with meeting the technical requirements of ISO 17025 and are familiar with the codes of practice for metering given in the Electricity Governance Rules. We offer advisory and training services to meet the measurement requirement of these codes.

Calibration Industry
We presently provide calibration services for the following types of equipment that are used to provide traceability into second-tier calibration laboratories and other industries with demand for high accuracy....more >>
Aviation Industry
We have experience in providing calibration certificates that meet FAA and CAA audit requirements. Examples of calibrated instruments include Fuel Gauge Test Sets as well as reference standards as described above.
Electricity Supply Industry
We provide for calibration of wattmeters capable of 0.2% or better, at currents up to 100 A at 50 Hz, and comparator bridges used for current and voltage transformer calibration. We also calibrate current transformers up to 3000 A at 50 Hz. Contact: Laurie Christian.
You are invited to participate in a proficiency testing programme for the calibration of wattmeters. We act as the pilot laboratory for the IANZ travelling watt-hour standard.
Consultancy Services
1. Calibration Industry
We are experienced in providing advice to assist you with meeting the technical requirements of ISO 17025.
2. Electricity Supply Industry
We are familiar with the codes of practice for metering given in the Electricity Governance Rules and offer advisory and training services to meet the measurement requirement of these codes. We can provide advice on calculating the overall uncertainty of metering installations and tailor computer programmes to meet your specific needs.
Current Transformer Proficiency Testing Programme
For the last 10 years, MSL has offered a successful and popular energy meter proficiency testing programme to electrical calibration laboratories in New Zealand. We now have available an adjustable error current transformer which can be circulated to calibration laboratories wishing to take part in a current transformer proficiency testing programme. The adjustable error current transformer has rated primary currents of up to 1000 A and has both 1 A and 5 A secondaries. MSL’s calibration report for the CT quotes best measurement uncertainties of 0.005% for ratio error and 0.005 crad for phase error at a 95% level of confidence.

RF and Microwave
RF Power
Power meters: We offer power meter and power sensor calibration for power levels up to 10 mW. The service provides traceable measurement of power sensor calibration factor over the range of frequencies from 30 MHz to 3000 MHz.
Least uncertainties are available from an automated service, at 1 mW, for HP8478-type thermistor mount sensors fitted with type-N connectors. Other types of sensor and connector systems may be calibrated on request.

More services planned
Power, impedance and attenuation are fundamental quantities in RF and microwave technology. They form the basis of traceable measurements in technological areas important to New Zealand, such as electromagnetic compatibility (EMC) and free-field measurements.
MSL is expanding its RF and microwave measurement capabilities by extending our coverage of frequencies upwards to 18 GHz and by introducing services to characterise impedance and attenuation.
