Normal business hours

Monday to Friday, 8am to 4:30pm

We are closed on public holidays

Accepted payment methods
  • Direct bank transfer
  • Card payment over the phone (Mastercard & Visa only)
  • Eftpos payment in store (Mastercard & Visa only)

We typically have a standardized pricing structure for calibrations

  • Most of the time we can provide a quote/estimate even without seeing the instrument in person.
  • Some instruments may require an inspection prior to formally quoting
  • Be aware a quote is only an estimate, the quote may need a variance after we have inspected or even begun the calibration procedure, for example if we find damage or faults with the instrument that were not expected and not within the initial scope of the job.
  • We will contact you with a revised quote before proceeding further where necessary.

We have a minimum fee of $80 +GST, this applies as a minimum inspection fee and also a minimum calibration attempt fee for any instrument processed through our facility.

  • Instruments that fail a calibration are generally still chargeable up to the full quoted price, we may at our discretion charge a lesser fee depending how much time and effort was spent working on the instrument.
  • For failed instruments if possible we may be able to offer a repair or replacement
  • Some instruments may carry a larger minimum fee, for example in cases where we need to send the instrument to a 3rd party for assessment, in these cases before moving forward we will quote an elevated minimum fee to cover the associated freight costs and 3rd party assessment fees.

Typical internal flow of a calibration

Typically, the whole calibration process is completed within 1 week.

  • This does vary and depends on various factors, but more often than not we are actually quicker.
  • Your instrument will go through various stages during a typical calibration, we are efficient at moving it between various stages in the process but sometimes delays can happen, we will inform you if we expect any kind of delay.
  • Some calibrations may be sent to a 3rd party partner or supplier, in which case they will carry a longer than our standard turnaround time. We do, however, strive to provide the very best and accurate estimate of turnaround time at time of quoting.

For expedited ‘same day’ or ‘next day’ service, Zedflo is the best calibration service to look to!

We are always busy and do have a constant stream of work in our laboratory, instruments are usually worked on in the order they are received, and then in order of confirmed approval to proceed with quote, but for a fee your instrument can jump the queue when you require a fast turn around.

The fee will vary, and is subject to availability, but as a typical guide:

  • Next business day turn around add 30% to the normal fee
  • Same day (next on bench) turn around add 50% to the normal fee

Residual Current Device (RCD) testers are critical in maintaining electrical safety. These sophisticated devices are essential for testing electrical systems to prevent hazards like electric shocks and fires, ensuring safety in commercial and industrial environments. Regular calibration of RCD testers is crucial for accurate performance, protecting your business from potential liabilities and enhancing operational safety. By prioritising accurate and reliable testing with RCD testers, you safeguard not only your infrastructure but also the well-being of your personnel.

What is an RCD Tester?

An RCD tester safely trips your RCD (residual current device) to ensure it operates safely during an abnormal electrical event or whether your electrical system is faulty.

Key Functions and Uses of RCD Testers

Trip Time Management

One of the primary functions of an RCD tester is to measure the RCD’s tripping time, which is the time it takes for the RCD to break the circuit once a fault is detected.

Accurate measurement of tripping time is crucial, as it indicates how quickly an RCD can respond to prevent electric shock or fire hazards.

RCD testers simulate fault conditions to test whether RCDs trip within the timeframes specified by safety standards.

Tripping Current Measurement

RCD testers also measure the tripping current, the minimum current at which the RCD will trip.

This function ensures that the RCD is sensitive enough to detect and respond to dangerous current levels, protecting against electrical faults that could lead to serious injury or damage.

 

Ramp Test Function

The ramp test function gradually increases the fault current to determine the exact current level at which the RCD trips.

This test is important for assessing the sensitivity of the RCD and ensuring that it operates within the specified current range.

It helps identify RCDs that are either too sensitive, causing unnecessary tripping, or not sensitive enough, posing a safety risk.

Use in Routine Safety Checks

RCD testers are used in routine safety checks and maintenance of residential, commercial, and industrial electrical installations.

They ensure that RCDs function correctly and provide the necessary protection against electrical faults, contributing to overall electrical safety.

Compliance and Certification

Testing RCDs with an RCD tester is a requirement for compliance with electrical safety standards and regulations.

It is also essential for electricians and technicians to certify that electrical installations are safe and meet the necessary safety criteria.

Impact of Inaccurate RCD Readings

Inaccurate RCD readings can have far-reaching consequences, from compromising the safety of individuals to legal ramifications for businesses and professionals. Understanding the impact of these inaccuracies underscores the critical need for regular calibration and maintenance of RCD testers.

Compromised Safety

The most immediate and concerning impact of inaccurate RCD readings is the potential compromise to safety. RCDs are designed to prevent electric shock by rapidly disconnecting the electricity supply when a fault is detected. If an RCD tester provides inaccurate readings, a malfunctioning RCD might not be identified, leaving circuits unprotected.

Increased Risk of Electrical Fires

Inaccurate RCD readings can also increase the risk of electrical fires. An RCD that fails to trip at the correct, current level can allow electrical faults to escalate unchecked, potentially leading to overheating, sparking, and, ultimately, fires.

Legal and Financial Repercussions

Inaccurate RCD readings that lead to undetected faults can result in non-compliance, exposing businesses to legal action, hefty fines, and damage to reputation.

Moreover, in the event of an accident, the inability to demonstrate due diligence in maintaining and calibrating RCD testers can lead to severe legal and financial consequences.

RCD Tester Calibration FAQ

Calibration frequency can depend on several factors, including the manufacturer’s recommendations, the frequency of use, and the environmental conditions where the tester is used.

Annual calibration is recommended, but more frequent calibration may be necessary for testers used heavily or in harsh conditions.

Signs that your RCD tester may need calibration include inconsistent or suspect readings, physical damage to the tester, a failed self-test (if applicable), or exposure to environmental extremes.

Failing to calibrate an RCD tester can lead to undetected faulty RCDs, increased risk of electric shock or fire, non-compliance with safety regulations, and potential legal and financial repercussions.
