Clamp Meter Calibration Services
Current readings without breaking the circuit — as long as the jaws are telling the truth.
ACS Calibration delivers NIST-traceable, audit-ready clamp meter calibration, available at the ACS central lab or directly on-site at facilities across the Southeast. DC and AC voltage, current, resistance, and capacitance — sourcing and measuring — are on our accredited electrical scope, so ISO/IEC 17025 accredited certificates are available on request.
What the Jaws Know
Clamp meters earn their place by measuring current without opening the circuit — motor draw, panel loads, leakage hunting — but the magic lives in the jaws, and the jaws lead a hard life. Misaligned mating faces, weakened hinge springs, drifted Hall sensors on DC clamps: all of it skews readings while the meter looks perfectly healthy.
We calibrate clamp meters under our accredited electrical scope — current at multiple points across our accredited ranges, plus the voltage and resistance functions on the meter body — with as-found and as-left data documented. Higher current ranges beyond the accredited span receive NIST-traceable calibration with the same rigor.
Clamps rarely travel alone: the DMMs and true-RMS meters in the same bag, and the insulation testers on the same safety program, all calibrate on one cycle — in-lab or onsite.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
Why Companies Choose ACS for Clamp Meter Calibration
NIST-Traceable, Accredited on Request
Every calibration is NIST-traceable with real measurement data. DC/AC voltage, current, resistance, and capacitance are on our ISO/IEC 17025 accredited electrical scope — accredited certificates available whenever your quality system requires them.
4–6 Business Day Typical Turnaround
Keep production moving. Most instruments are typically completed in 4 to 6 business days from arrival, with rush options available when a line is down.
Flexible Logistics
Mail your instruments in, or schedule onsite calibration and we come to your floor — serving Alabama, Florida, Georgia, Mississippi, Tennessee, South Carolina, and beyond.
