For many manufacturers or laboratories, finding an ISO 17025 accredited calibration laboratory that offers onsite calibration services is a huge convenience. Tooling and production managers express that it is hard to plan calibration service for high priority pieces of equipment due to potential downtime. When last minute orders come up, it can be difficult to complete jobs while equipment is out for testing. The problem is exacerbated by the added cost of expedited or high priority shipping. Onsite calibration eliminates the stress and added costs of shipping equipment to the lab for calibration.
However, not all onsite calibration services are the same. Companies have two options, traditional onsite calibration or mobile onsite calibration. During traditional onsite service work is performed inside the facility. The calibration technicians will test equipment in an area designated by the equipment or production supervisor. Mobile calibration labs differ because the work is performed inside a trailer. Quality managers express concern over this type of service because testing procedures are performed away from the maintenance and quality staff. Performing testing and repairs in this fashion can be problematic if the staff questions calibration finding validity. When choosing onsite calibration, consider the following points:
Quality and production managers have communicated that they feel uneasy when testing or minor repairs are performed in a mobile calibration lab versus on the shop floor. A common concern is whether or not large volume physical dimension instruments are all properly checked. An example of this is pin gage calibration, a company may have 100+ pin gages that need to be tested. Quality and production professionals have greater peace of mind when they are able to see calibration technicians performing testing.
When performing onsite calibration, technicians will ideally be able to test in a controlled environment. When a team is performing work inside the hangar, there is very little control over temperature and humidity. If calibration is performed in a trailer, the calibration technicians can keep the temperature and humidity with a certain range. Conducting work in this manner makes testing procedures more closely mirror those performed in the laboratory.
The opportunity to ask questions during onsite calibration service is significantly decreased when calibration occurs in a mobile lab. A common scenario is when equipment fails calibration testing and requires adjustment. When this occurs, maintenance personnel can benefit by talking with the calibration technician to understand the issue. If calibration is performed on the shop floor, the technician can physically show maintenance professionals the causes of testing failure.
