We do not certify instruments for use in aircraft.

We perform all calibrations with NIST-traceable measurement results for use in ground test equipment only, not for flight or aircraft navigation.

We are not an FAA Repair Station and do not issue yellow return-to-service tags.

We replace a battery if it reads low on voltage during calibration. (For example, a 9-volt battery that measures below 9 volts.)

We also replace batteries in any unit that requires the case to be opened and the calibration seal to be broken.

If you install a new battery before sending your equipment in for calibration, you can avoid an additional battery charge.

Yes, we can perform a limited certification and clearly mark any range that does not meet requirements as not usable.

We only proceed with a limited certification with your prior approval.

We do not require customer leads to certify most handheld 3.5-digit multimeters.

If you would like us to check or replace your leads, please include them and note your request on the packing list or purchase order.

Some bench multimeters and other electrical meters require the use of the customer’s leads for calibration. If you aren’t sure you should send the leads along with the meter.

Many display issues, such as missing digits, result from oxidation on the display contacts.

We can often correct this by cleaning the instrument, which is included during the normal calibration process.
