Digital Multimeters (DMMs)
Handheld and benchtop DMMs across voltage, current, and resistance ranges. We verify accuracy from microvolts to kilovolts and milliohms to megaohms.

Electrical calibration services for the instruments your production depends on.
Orbital Metrology provides NIST-traceable electrical calibration for digital multimeters, oscilloscopes, power supplies, function generators, decade boxes, and clamp meters — with 24 to 72 hour turnaround targets for teams in Greater Seattle and nationwide.
Understanding the discipline
What is electrical calibration?
Electrical calibration is the process of comparing an instrument's measurements against a known reference standard and documenting any deviation. A digital multimeter that reads 10.00 V on a 10.00 V source, for example, might actually be reading 10.03 V. Without calibration, that error goes undetected — and compounds across every measurement the instrument makes.
The process applies to every electrical parameter: voltage (AC and DC), current, resistance, capacitance, inductance, frequency, and time. Each instrument type has its own calibration procedure, measurement points, and acceptance criteria defined by the manufacturer or an applicable standard.
Orbital Metrology performs electrical calibration under ISO/IEC 17025 quality system requirements, with full traceability to the National Institute of Standards and Technology (NIST). Every calibration produces a certificate with measurement results, uncertainty statements, and the reference standards used — ready for your next audit.
Instruments we calibrate
Electrical instruments across every parameter.
From handheld clamp meters on a factory floor to benchtop oscilloscopes in a design lab, Orbital calibrates the electrical instruments that keep your measurement chain intact.
Oscilloscopes
Bandwidth, rise time, gain accuracy, and time-base verification for analog and digital oscilloscopes. Multi-channel cal to manufacturer specs.
Power Supplies
DC power supplies, programmable supplies, and bench supplies calibrated for voltage accuracy, current limiting, load regulation, and ripple.
Decade Boxes
Resistance, capacitance, and inductance decade boxes verified across their full switching range to manufacturer tolerances.
Function Generators
Waveform generators calibrated for frequency accuracy, amplitude flatness, DC offset, distortion, and output impedance.
Clamp Meters
AC and DC clamp meters calibrated across current ranges from milliamps to hundreds of amps, plus voltage and resistance functions.
Why electrical calibration matters
Measurement drift is invisible. The consequences are not.
Measurement confidence
Electrical instruments drift over time. Calibration verifies that your DMM, scope, or source still measures within specification — before a bad reading costs a batch, a flight clearance, or a patient safety event.
Regulatory compliance
Aerospace primes, FDA-regulated manufacturers, and defense contractors require documented, traceable calibration on every instrument in the measurement chain. Un-calibrated tools create audit findings and production holds.
Production continuity
When instruments sit at a vendor for two weeks, your bench sits idle. Orbital's fast-turn electrical calibration keeps your measurement capability online and your schedule on track.
NIST traceability
Every Orbital calibration tracees back to NIST through an unbroken chain of reference standards. Our reference instruments are calibrated by accredited laboratories and maintained on documented calibration intervals. The traceability chain is documented on every certificate, so your quality team can verify it during audits without chasing paperwork.
NIST traceability is not optional for aerospace primes, medical device manufacturers, or defense suppliers. It is the foundation that makes calibration certificates credible. Without it, a certificate is just a number.
ISO/IEC 17025 accreditation
Orbital Metrology operates under ISO/IEC 17025, the international standard for calibration and testing laboratories. This means our methods, environment, equipment, personnel, and quality system are independently evaluated to ensure competence and consistency.
For your team, ISO 17025 means the calibration results are defensible. Regulators, auditors, and customers accept ISO 17025 accredited calibration as evidence that your measurement chain is under control. It is the difference between a certificate that gets filed and one that holds up under scrutiny.
The turnaround advantage
24–72 hours, not 8–14 days.
The industry standard for electrical calibration turnaround is eight to fourteen business days. For a manufacturer running production test benches, that means instruments are offline for nearly three weeks — counting pickup, queue time, calibration, and return shipping.
Orbital targets 24 to 72 hour bench turnaround for standard electrical calibration. Your instruments are on the bench the day they arrive, not sitting in a queue behind someone else's backlog.
Fast bench turnaround
Standard electrical calibration is completed within 24 to 72 hours of arrival. Complex instruments or multi-parameter calibrations may take slightly longer, but we communicate the timeline before work begins.
Same-day certificates
Calibration certificates are issued the same day calibration is completed — no waiting days for paperwork to clear a back-office queue.
No production hold
Fast turnaround means your test benches, verification stations, and production lines stay instrumented. Downtime shrinks from weeks to days.
No quality compromise
Speed does not mean shortcuts. Every calibration follows documented procedures with full NIST traceability and uncertainty statements, regardless of how fast it ships back.
Industries served
Electrical calibration for regulated and high-performance environments.
Orbital supports teams where calibrated electrical instruments are not a nice-to-have — they are a production requirement.
Aerospace and defense
Production test benches, avionics verification, and flight-critical measurement chains that demand NIST traceability and audit-ready documentation. With Boeing ramping 737 production in Renton and opening a 4th line in Everett, Tier 1 and Tier 2 suppliers across the Puget Sound corridor need calibrated electrical instruments that keep up with accelerated quality audits.
Medical device manufacturing
FDA 21 CFR Part 820 compliance requires calibrated test equipment. We support Class I through Class III device manufacturers with rapid turnaround.
Electronics and semiconductor
Bench instruments, automated test equipment (ATE), and characterization tools that run 24/7 and cannot afford long vendor lead times.
Technology and R&D
Prototype labs, university research groups, and engineering teams that need fast, documented calibration without the overhead of a national lab queue.
