Calibration and Verification

11.2.1 Factory calibration

Every AMETEK CTS generator is entirely checked and calibrated as per international standard regulations before
delivery. A calibration certificate is issued and delivered along with a list of the equipment used for the calibration
proving the traceability of the measuring equipment. All auxiliary equipment and accessories are checked to our
internal manufacturer guidelines.
The calibration certificate and the certificate of compliance (if available) show the date of calibration.
The AMETEK CTS equipment are calibrated in the factory and marked with a
calibration mark. The used measuring instruments are traceable to the Swiss Federal
Office of Metrology.
The calibration date is marked. The validity of the calibration is to the responsibility
of the user's quality system. Neither the certificate of calibration nor the
corresponding label mark any due date for re-calibration.

11.2.2 Guideline to determine the calibration period of AMETEK CTS instrumentation

Our International Service Departments and our QA Manager are frequently asked about the calibration interval of
AMETEK CTS equipment.
AMETEK CTS doesn't know each customer's Quality Assurance Policy nor do we know how often the equipment
is used and what kind of tests is performed during the life cycle of test equipment. Only the customer knows all
the details and therefore the customer needs to specify the calibration interval for his test equipment.
In reply to all these questions we like to approach this issue as follows:
AMETEK CTS make use of a solid-state semiconductor switch technique to generate high voltage transients. A
precious advantage of this technique is the absolute lack of periodical maintenance effort. In consequence,
thereof a useful calibration period must be defined based on two criteria:
The first one is the customer's Quality Assurance Policy. Any existent internal regulation must be applied at
-
highest priority. In the absence of such internal regulation the utilization rate of the test equipment must be
taken into consideration.
- Based on the experience and observation collected over the years AMETEK CTS recommends a calibration
interval of 1 year for frequently used equipment. A 2-years calibration interval is considered sufficient for
rarely used test generators in order to assure proper performance and compliance to the standard
specifications.

11.2.3 Calibration of Accessories made by passive components only

Passive components do not change their technical specification during storage. Consequently, the measured
values and the plots stay valid throughout the storage time. The date of shipment shall be considered as the date
of calibration.

11.2.4 Periodically In-house verification

Please refer to the corresponding standard before carrying out a calibration or verification. The standard
describes the procedure, the tolerances and the necessary auxiliary means. Suitable calibration adapters are
needed. To compare the verification results, AMETEK CTS suggests refer to the waveshape and values of the
original calibration certificate.
All calibrations and verifications are always done without mains supply voltage connected to the coupling network
input.
