Electrical Calibrations


Providing Quality and Accredited Electrical Calibrations

Electrical calibrations are an important part in maintaining your electrical test equipment so that they continually provide accurate and reliable readings. Since drift can occur over time, it is best to have your electrical equipment routinely calibrated. Doing this helps verify the performance of the component’s measuring parameters, ensuring the end user has accurate readings.

Electrical calibrations are important to maintain whether your equipment is being used as part of a maintenance or preventive maintenance program or if it’s being used for an occasional need, such as troubleshooting. All electrical test equipment should be calibrated at least once every year if not more.

As a full service laboratory, Constellation PowerLabs has the advanced capabilities to calibrate both AC and DC currents, resistances, voltages, inductance, and capacitance.

Our Capabilities for Electrical Calibrations

Through our diverse array of electrical calibrations and team of highly trained technicians, we are able to calibrate a multitude of different types of electrical test equipment. We have calibrated thousands of different manufacturers and models of electrical equipment, with approved procedures to help our technicians perform electrical calibrations successfully.

If we have not previously seen or calibrated a specific manufacturer and model number in our labs, we will develop a  new procedure. Our team will create and write a new format based on the manufacturer specifications so that you can still have your equipment calibrated in a timely manner. As we continue to advance in our RF calibrations and microwave calibration capabilities, so does our equipment. Here are just some of the different types of equipment we use to help us provide greater calibration accuracy to our customers.
