Calibration discipline

What is Electrical & Electromagnetic calibration?

Quick answer

Electrical & electromagnetic calibration (DC/AC low frequency) determines the error of instruments that measure & source electrical quantities: voltage, current, resistance, capacitance, frequency, power. Techmaster’s ISO/IEC 17025:2017 lab is traceable to the volt (V) and ohm (Ω).

Electrical instruments are the backbone of electronics test, EMS, energy and electrical safety. Drifting DMMs, sources and scopes corrupt every downstream measurement — causing scrap, wrong assessments and safety risk.

Techmaster calibrates electrical instruments with high-accuracy multifunction calibrators, traceable to the SI volt and ohm; well suited to electronics, semiconductor plants and labs.

Calibration scope

Quantities & parameters we calibrate

DC & AC voltage (DCV/ACV)

Measurement range

Typical measurement ranges & CMC

The table below lists typical parameters & measurement ranges for this discipline.

Parameter / Instrument Typical measurement range CMC / Measurement uncertainty
DC voltage 0 – 1000 V [Verify against scope]
DC current 0 – 20 A [Verify against scope]
Resistance 0 Ω – 100 MΩ [Verify against scope]
AC voltage up to 1000 V, up to 100 kHz [Verify against scope]
Frequency (LF) up to several MHz [Verify against scope]

Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.

Standards & traceability

Reference standards & traceability

Electrical measurements are traceable to the SI volt (V) and ohm (Ω) through certified multifunction calibrators (e.g. Fluke 5xxx), in turn traceable to Josephson/quantum-Hall standards at the national level.

Q & A

Frequently asked questions

Which multimeters can Techmaster calibrate? +
Handheld and bench DMMs across accuracy classes and counts, covering DCV/ACV, DCI/ACI, resistance, capacitance and frequency. Results include measurement uncertainty.
Do you calibrate oscilloscopes? +
Yes. Techmaster calibrates key oscilloscope parameters (amplitude accuracy, timebase/bandwidth, etc.) using a dedicated oscilloscope calibrator.
Can electrical safety testers be calibrated? +
Yes. Techmaster calibrates insulation resistance, earth resistance and electrical safety testers within scope.
Lab or on-site for electrical instruments? +
Most DMMs and clamp meters can be done in the lab or on-site. Fixed or line equipment can be calibrated on-site with calibrated portable standards.
