22 Maintenance - Recalibration

22.1 Housing Maintenance

No special maintenance is required for the housing. Keep outside

surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the

use of cleansers, abrasives or solvents.

22.2 Recalibration

The respective measuring task and the stress to which your measuring in-

strument is subjected affect the ageing of the components and may result

in deviations from the guaranteed accuracy.

If high measuring accuracy is required and the instrument is frequently

used in field applications, combined with transport stress and great tem-

perature fluctuations, we recommend a relatively short calibration interval

of 1 year. If your measuring instrument is mainly used in the laboratory and

indoors without being exposed to any major climatic or mechanical stress,

a calibration interval of 2-3 years is usually sufficient.

During recalibration* in an accredited calibration laboratory

(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to

traceable standards are measured and documented. The deviations de-

termined in the process are used for correction of the readings during

subsequent application.

We are pleased to perform DKD or factory calibrations for you in our cali-

bration laboratory. Please visit our website at www.gossenmetrawatt.com

( Services  DKD Calibration Center or  FAQs  Calibration ques-

tions and answers).

By having your measuring instrument calibrated regularly, you fulfill the re-

quirements of a quality management system per DIN EN ISO 9001.

Standards DIN VDE 0701-0702 and IEC 63353 (VDE 0751) stipulate that

only measuring instruments which are regularly tested and calibrated may

be used for testing.

* Verification of specifications or adjustment services are not part of the calibration.

For products from our factory, however, any necessary adjustment is frequently

performed and the observance of the relevant specification is confirmed.

22.3 Safety Checks

Check the safety of your test instrument on a regular basis. We recom-

mend the same test intervals as for recalibration.

The SECUTEST... is designed as a totally insulated instrument in accor-

dance with standards IEC 61010 and VDE 0404. The protective conduc-

tor is only used for measurement purposes and is therefore not accessible

in idle state. A protective conductor test at the test socket can be per-

formed as follows:

Ð Connect the SECUTEST... to a multiple distribution box.

Ð Conduct a contact current measurement for permanently installed

DUTs (the test socket may not be connected to any load).

Ð Measure the protective conductor resistance between the neighbour-

ing socket of the multiple distribution box and the test socket.

Ð The measured value may not exceed 0.3 .

Insulation resistance between LN and PE in the SECUTEST... equals ap-

prox. 150 kfor metrological reasons.

This must be taken into account when performing the safety checks, i.e.

the protective conductor current measurement must produce a value

below 3.5 mA, instead of insulation resistance measurement (if the equiv-

alent leakage current measurement method has been chosen, the value

must remain below 7 mA).

Apart from this, the SECUTEST... features 3 exposed conductive parts for

which contact current measurement must produce a value below 0.5 mA:

• RS232 interface

• metallized start key

• protective conductor clip at the test socket.
