What is Electrical & Electromagnetic calibration?
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.

Instruments Techmaster calibrates
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.
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.
