Calibration
All Megavar test equipment is maintained under a documented calibration programme. Instruments are calibrated either by external calibration laboratories or in-house against reference standards that are themselves laboratory-calibrated, with measurement traceable to Australian national measurement standards held by the National Measurement Institute. A current calibration certificate is available on request. If your project requires a specific calibration interval, test standard, or documentation for a client submission, tell us at enquiry on 1300 730 499 and we will confirm what applies before you commit.

How the hire works
Hire terms in brief
After you enquire
We confirm availability, rates and freight in a written quote, valid for the period it states (usually 14 days). An enquiry or quote does not reserve equipment: the hire is booked when your purchase order, signed quote or email acceptance reaches us.
Hire period
Our carrier: up to 72 hours of transit each way is not charged as hire. Hire starts at delivery or 72 hours after dispatch, whichever is earlier, and ends at handover to our carrier or 72 hours before the equipment arrives back, whichever is later. Delay caused by us or our carrier is not charged. For example, dispatched Monday 10am and delivered Wednesday 2pm: hire starts Wednesday 2pm. Routes that normally take longer than 72 hours are marked on the quote. Your own freight: hire runs from handover to your carrier at our office until the equipment arrives back at our office. Collect in person: from collection to return.
Extensions and early return
Contact us before the return deadline to extend; your quoted rates stay fixed and extended hire is invoiced every 7 days. Return early and you pay only for the days used, at the rate band for the days actually hired.
Delivery and returns
Freight for each leg, the handling fee and any express dispatch are on the quote, before you accept. Returns go to the dispatching office named on the quote, by carrier or in person, never by post.
Counter times
Returned to our counter before 9am on a business day counts as the previous day. Collected after 4pm on a business day, hire starts the next day. Weekends and public holidays count as hire days.
Calibration and checks
Supplied in working order with listed accessories, leads and manuals. Each measuring instrument is calibrated, and its current NATA-traceable calibration certificate is available on request. If calibration falls due during your hire, we tell you before dispatch.
Cancelling or moving a booking
Cancel 5 or more business days before dispatch or collection and nothing is charged. With 2 to 4 business days’ notice, the charge is the greater of one day’s hire and 5% of the booked hire; with less notice, the greater of one day’s hire and 10%. You can ask once to move the start by up to 30 days, with at least 2 business days’ notice.
Loss, damage and insurance
The equipment is your responsibility, other than fair wear and tear, from the start of hire until it is back with us, including in transit, up to the replacement value cap shown on the quote for each item. No damage waiver is offered. We recommend you insure the equipment for its replacement value.
Payment and bond
Account customers pay each invoice within 14 days. Without a credit account, or paying by card, you pay the booked hire, freight, handling fee and any bond before dispatch. A bond applies only where the quote states one, and is refunded after return and inspection, less anything owed.

FAQ
Frequently Asked Questions
AEMC 6471 Ground Resistance Tester
What the AEMC 6471 is used for?
The AEMC 6471 is a multifunction ground resistance tester covering 3-point fall-of-potential, 4-point soil resistivity, selective and stakeless measurement methods. That range makes it a single-instrument hire for earthing work: verifying electrode resistance, measuring soil resistivity for earthing design, and testing bonds and connections without disconnecting the system.
Typical hire scenarios: soil resistivity surveys ahead of substation or renewable earthing design, earth grid verification during commissioning, and periodic earth testing on existing installations. Megavar’s earthing engineers use these methods daily and can support test planning or run the survey for you.
What test methods does it support?
The 6471 supports:
• 2-pole and 3-pole earth resistance testing
• 4-pole soil resistivity testing (Wenner method)
• Selective and stakeless testing using clamps
• Bonding and continuity testing
What’s the difference between selective and stakeless testing?
- Selective testing allows earth resistance measurements without disconnecting the ground using a current clamp.
- Stakeless testing eliminates the need for auxiliary ground stakes and uses two clamps for fast, non-intrusive testing.
Do I need special accessories?
The instrument works with standard stakes and leads. For selective or stakeless testing, optional current and voltage clamps are required (can be rented with the unit).
Can it be used near power lines or substations?
Yes. The 6471 has a built-in noise rejection system and selectable test frequencies to reduce the effects of interference in high-voltage environments.
What’s included in the rental?
• AEMC 6471 unit
• 3 or 4 test leads and ground stakes
• Rechargeable battery and charger
• Carry case
• Quick-start guide
• Optional: Clamp set for stakeless testing (on request)
What’s the minimum rental period?
The minimum hire is one day. The daily rate steps down for hires of 8 days or more, and longer project hires can be quoted on 1300 730 499.
What support comes with the hire?
Each instrument is supplied with the manufacturer’s manuals. If a set plays up, call us and we will arrange a fix or a replacement.
Do you deliver across Australia?
Yes. Door-to-door delivery and pickup available nationwide.
Is a deposit required?
A security deposit may apply. For business hires, proof of insurance may be requested depending on the rental terms.
