9.0 Maintenance

Warning

To avoid possible electric shock, personal injury or sudden release of pressure, review
“Safety Instructions” Section 2.0 before proceeding.

Only qualified service personnel should perform calibration, repairs, or service not covered by
this manual.

For maintenance procedures not described in this manual, or if the ASC-400 calibrator needs
repair, please contact AMETEK Denmark Service Department as described below in section 9.1
“Returning the calibrator to service”.

9.1

Returning the calibrator to service

If the calibrator continuously malfunctions, verify that the instrument is being operated as
described in this manual and return it to the manufacturer for repair/service.

If the calibrator needs repair and is under warranty, see the warranty statement section 1.1 for
terms. If the warranty has lapsed, the calibrator can be repaired and returned for a fixed fee.

When returning the instrument please enclose a fully completed service information form.
Simply copy the “Service info” form from the following page and fill in the required information.
The calibrator should be returned in the original packing.

Note…

AMETEK Denmark’s liability ceases if:
