Instrument Calibration Frequently Asked Questions

Is there a difference between calibration and adjustment?

There is a common misconception that by calibrating a measurement device, it is being made to read the exact value being applied. This is not the case.

In fact, calibration is actually the process of correlating an instrument’s readings with those of a standard with the intention of recording the instrument’s accuracy and comparing them against the manufacturer’s specification or relevant standards.

Adjustment, on the other hand, is the act of bringing a measurement device’s readings to within the tolerances laid out by the manufacturer’s specification or relevant standards.

What if my unit fails calibration?

Depending on the severity of the failure, we will try to obtain a set of readings containing the failed results. If the unit is unable to make readings, or the readings are erratic, then recording the erroneous readings will not be possible. You will be notified immediately and given the following options:

  • Have the unit returned the unit as is,
  • Get a quotation for adjustments/repairs,
  • Request a quote for a new instrument or visit our shop for an extensive range of equipment.
  • Have the unit scrapped, we will take care of disposal.

What if my instrument is constantly in use?

For large companies who need their equipment calibrated with as little downtime as possible, we offer an onsite service whereby we come to you and test your equipment at your facility. This can usually be done in a day but for large onsite orders this can be longer.

We don’t just serve the larger companies; we also provide a while-you-wait service for 17th edition electrical test equipment at no extra charge. Just call us in advance so that we can book you in. This service typically takes up to an hour but please allow for two.

What am I getting for my money?

By having your equipment calibrated with us, you will receive the following service:

  • Calibration Certificate traceable to National Standards
  • Calibration Label detailing the instrument’s serial number, the certificate number, calibration date and calibration due date (52 weeks as standard if not instructed otherwise)
  • Clean: If your instrument is dirty, we will clean it up as best we can.
  • Apply fresh “void if broken” seals to the instrument

We make every effort to keep our customers happy, if in the unlikely event that we miss something, please tell us. We will sort out any problems you have right away.

How quickly can you test my equipment?

Our standard turnaround time for our laboratory calibrations is three working days. That is from the time your equipment reaches us to the time it leaves us. If you need a quicker service than this please tell us, we will always try to accommodate any special requests.

Direct Calibration Solutions offers a while-you-wait calibration service for all 17th edition test equipment. This is usually a one-hour turnaround time but please allow for up to two hours. Just remember to Contact Us in advance to we can arrange a day to book you in.

For sub-contracted items this is usually 7-14 days, although we are entirely at the mercy of our suppliers. Because of this we have made massive efforts to build an effective database of efficient, reliable sub-contractors.

How much is return carriage?

Return carriage is £10+vat.

This covers delivery of your test equipment to a single delivery address. If you require multiple items to be returned to multiple delivery addresses, you will be charged £10+vat for each delivery address.

Your items will be well packaged using any combination of bubble wrap, packing chips or recycled packaging.
