THE FIELD NOTES
DC & batteries
Small currents. Measurable disturbances.
LOW-CURRENT MEASUREMENT
Can a 1 mA clamp resolve 20 mA?
Separate display resolution from low-current capability, including zero drift, clamp position, magnetic history and the limits of multi-turn tests.
6 MIN READ ↗BURDEN VOLTAGEWhen the meter changes the circuit.
Understand burden voltage in low-voltage DC current measurement, with a worked example, an original circuit diagram and a recording checklist.
6 MIN READ ↗Begin with a defined measurement.
These guides explain published specifications and method limitations. Calculations are illustrative; product observations are attributed to the original author. Use the exact manual for your instrument and record the operating conditions.
