Multimeter calibration for manufacturing
Maintenance and quality teams on Perth production floors use multimeters to check sensors, drives and control voltages. An ISO 9001 auditor will ask for the calibration record of any meter whose reading appears in a maintenance or inspection record.
The multimeter is the instrument most electricians and technicians trust without thinking about it, which is exactly why it needs a traceable calibration. AmpTech calibrates handheld and bench digital multimeters in our Caversham lab against reference standards traceable to national standards, and returns them with a certificate showing where each range sat before and after adjustment.
Interval in manufacturing
12 months
ISO 9001 monitoring and measuring resources
Setting the interval
Twelve months is the near-universal manufacturer and quality-system default. Meters used daily on site, exposed to heat and vibration, or used for safety-critical measurements are often placed on a shorter interval.
What the calibration covers
- DC voltage at points across each range, from millivolts to the top of the highest range
- AC voltage at several amplitudes and at mains and higher test frequencies
- DC and AC current on every current range, including the milliamp and microamp ranges
- Resistance from a short-circuit zero through each range
- Frequency, and capacitance where the meter offers it
- Continuity beeper threshold and diode test function
What your certificate records
The certificate format manufacturing procurement and audit teams ask for: the equipment under test, its serial number, the reference instruments used, as-found and as-left readings, environmental conditions and a traceability statement, plus the multimeter-specific items below.
- As-found and as-left readings for every range and function tested
- The reference instruments used, with their own traceability
- Whether the meter met its manufacturer specification on each range
- Environmental conditions at the time of calibration
Standards & frameworks in manufacturing
- ISO 9001 quality management system
- ISO 10012 (referenced) — measurement management
- AS/NZS 3760 for portable electrical equipment on plant
- Customer-specific PPAP / quality requirements
How manufacturing clients get multimeters to us
Calibration is performed in our Caversham lab — not on site. We collect from and deliver back to manufacturing workshops and offices across Perth, and instruments from regional sites come by freight or via your Perth base.
- Canning Vale and Bibra Lake manufacturing precincts
- Welshpool and Kewdale fabrication and assembly workshops
- Malaga light industrial and trade workshops
- Osborne Park commercial and QC laboratories
Working with manufacturing procurement
We work with quality and production teams to align calibration intervals with your control plan, supply certificates that map directly to your gauge register, and schedule recall reminders so nothing falls out of cal during a production run.
