Digital Multimeter Calibration in Bangladesh
ION Engineering calibrates digital multimeters across voltage, current and resistance ranges against traceable electrical reference standards, accredited to ISO/IEC 17025:2017.
What We Calibrate
DC & AC Voltage
Voltage ranges calibrated against a traceable electrical reference source.
DC & AC Current
Current ranges calibrated across the meter’s rated scale.
Resistance & Continuity
Resistance ranges and continuity function verified against known references.
How We Calibrate a Multimeter
The multimeter is tested at multiple points across each function and range — voltage, current and resistance — against a traceable electrical reference source, with as-found and as-left readings recorded to confirm the instrument reads within its stated accuracy.
What’s included
- Multi-point calibration across each function and range
- As-found and as-left readings, per point
- Stated measurement uncertainty
- QR-verifiable certificate

Digital Multimeter Calibration FAQs
How often should a multimeter be calibrated?
Annually is standard for most workshop and field multimeters, with more frequent calibration for meters used in safety-critical or high-precision measurements.
Do you calibrate every function and range?
We calibrate the functions and ranges you actually use, agreed with you before the visit, rather than a blanket check of every possible setting.
What measurement uncertainty do you report?
Uncertainty is stated per range on your certificate; our full accredited scope is published on our calibration capabilities page.
Is the certificate independently verifiable?
Yes, every certificate number can be checked using our online verification tool, with no login required.
