How often do I need to have my instruments calibrated?

There is no periodicity stated in a British Standard. However most calibrations in the UK are carried out over a 12 month cycle.

How do I set up a system for calibration acceptance criteria?

You must determine each instrument has the accuracy necessary to ensure that they are suitable for the measurement or monitoring requirement that they are intended for.

What are my options when equipment works correctly on some but not all ranges?

Equipment can be used when only working on some ranges but it must be labelled very clearly to ensure that the end user is fully aware of the limitations. In some circumstances use of equipment with limited functionality may be subject to a risk assessment.

If integrity seals must be broken in order to change the batteries, how is calibration validity maintained?

When the calibration seals are broken by the end user, the calibration validity is compromised. However it does seem a little drastic to return the unit for recalibration immediately after replacing the disposable batteries. We believe that the best solution is to update your working procedures with an instruction to reseal the unit with integrity seals after a battery change.

Do I need to send test leads with the equipment for calibration?

There is no requirement to return leads for standard equipment. The only real exception to this is for the instrument lead to mains plug should be returned with a loop impedance tester as the mains lead is taken as part of the measured value.

Why is acclimatisation an issue and which types of equipment for calibration are most sensitive to temperature variation?

Wherever possible equipment should always be acclimatised overnight prior to calibration. This becomes a necessity for some equipment to ensure that a state of equilibrium is attained between the equipment and the standard, thus ensuring the accuracy of the measurement.

What happens if my instrument needs to be repaired whilst Pennine Instruments are undertaking the calibration?

You will be contacted and informed about price and timescale as soon as possible. No charges will be incurred before we talk to you.

Can Pennine Instruments remind me when my next calibration is due?

Pennine offers reminder service (normally by email) the month prior to calibration expiry.
