Current Balance

The current balance measures small currents through the principle of electromagnetic force balance, utilizing the torque generated by a current-carrying coil in a magnetic field, which is proportional to the measured current. It is used for calibrating microampere-level ammeters, verifying Ohm's law, and detecting leakage currents in semiconductor devices, playing a role in electrical metrology and electronic component testing.
Selection
When selecting, pay attention to the matching of the range to the measured current, ensuring the resolution meets the measurement accuracy requirements. Consider temperature drift and electromagnetic interference protection. Verify the validity of the calibration certificate, ensure interface compatibility with existing systems, and confirm that the operation process aligns with user habits. Balance maintenance costs with service life.
