Service and maintenance
|
|
Our precision measuring instruments require basically no servicing.
|
|
Nevertheless, to assure a long-service life for your Microtest 3-point internal micrometer, we recommend that the device is always kept clean. If it becomes soiled by cooling water or particles of dirt, it is enough to just wipe the instrument down with a cloth to prevent unnecessary malfunctions that result if moving parts stick.
|
|
Because the Microtest internal micrometers require no servicing, repair or overhaul is only due after between 5 and 10 years.
|
|
Normally, provided no heavy damage has occurred, the instrument can be overhauled for a price that does not exceed 25 % of the initial acquisition price (up to 10 years). This involves the following work:
|
- complete dismounting
- cleaning
- replacement of faulty parts
- correction of the accuracy to the original tolerance (up to 10 years)
- factory certification |
| When your instrument is returned it measures as accurately as a new one. |
| Repairs |
|
Additional parts replaced as a result of the instrument being dropped or other heavy damage will be charged for.
|
|
Calibration
|
|
All the measuring instruments and gauges that we supply are uniquely identifiable through an unique device number, and are examined, re-calibrated and certified for a small fee. |
|
Repair time
|
|
Because the precise measurement and correction of measured results in particular does take a great deal of time, the turnaround time is about 2 to 4 weeks, depending on the state of the device.
|
|
Alternative devices
|
|
In urgent cases we can make alternative devices available to our customers to bridge the repair time. The charges involved depend on the measuring range and the period of use.
|
|
Certificate of accuracy
|
|
Since the company was founded, every one of our instruments has been delivered with a certificate of accuracy, detailing the linearity accuracy at various points along the entire measurement range. |
| Declaration of Conformity |
