Overview
About the Red Phase 4022C Continuity Tester
Description
The Red Phase 4022C is a remote bonding continuity tester designed for verifying low-resistance connections in earthing systems, bonding conductors, and HV electrical infrastructure. Injecting a regulated DC test current of about 1 A through a four-terminal connection, it measures the loop resistance across joints, connections, and welded points in substation earth grids, transformer earthing, and structural bonding systems. The 4022C is rugged, portable, and designed for field use with clear output indication and a proven track record in utility and commissioning applications.
Features
• Four-terminal DC resistance measurement from 0 to 1999 mΩ with about 1 A injection
• Designed for low-resistance measurement in substation earthing systems
• Manual test trigger with LED and audible status indication
• Suitable for testing welded earth connections, bonding cables, and cable lugs
• Robust build for outdoor and high-voltage environments
• Clear PASS/FAIL indication based on set thresholds
• Long leads and high-capacity clamps for flexible deployment
• Mains (85 to 265 V AC) or internal rechargeable battery operation, three to four hours per charge
• Quick test duration minimises heating at test points
• Supplied in transportable case with leads, clamps, and operation guide

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
Red Phase 4022C Continuity Tester
What is the 4022C used for?
It is used to verify low-resistance bonding between earth grid components, ensuring effective fault current paths and compliance with substation earthing standards.
What current does it output?
The tester injects about 1 A DC through a four-terminal connection and reads the loop resistance on a 3.5-digit display (0 to 1999 mΩ), which is sufficient to prove a bond without a high-current ductor.
Is it suitable for substations?
Yes. It is specifically designed for substation environments and is widely used by utilities, HV contractors, and commissioning engineers.
What types of tests can I perform?
• Welded and mechanical joint continuity
• Transformer bonding verification
• Switchyard and gantry bonding tests
• Cable tray and earth grid connection checks
How is the test controlled?
Testing is initiated manually with a start switch. Visual (LED) and audible indicators signal test progress and result (pass/fail).
Does it display resistance values?
Yes, from 0 to 1999 mΩ with better than 1 per cent accuracy. For micro-ohm measurements on breaker contacts or busbar joints use a DLRO or the MOM3.
What’s included in the rental?
• 4022C main unit
• Output cables and heavy-duty clamps
• Power lead and user guide
• Rugged transport case
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.
What’s the minimum hire 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.
Do you deliver nationwide?
Yes. We offer Australia-wide delivery and pickup, or you can organise your own freight.
