Calibrating Multimeters and Multifunction Process Calibrators
According to the QLD Electrical Safety Act
2002 - Section 18 - (2)(b) : if a testing instrument can not be visually confirmed as being
correctly functioning and safe - that the instrument is tested at least every 6
months to ensure it is in proper working order.

Ensure your equipment is in specification so that any electrical testing you do is conducted in
accordance with AS/NZS 3760 "In-service safety inspection and testing of electrical equipment" or any
installation work is done in accordance with AS/NZS 3000 "Electrical installations - Wiring
Rules"
All measurements are traceable to national and international
standards via a registered NATA laboratory or a mutually recognised international testing authority. (See
NATA’s International Activities )
