7 Maintenance and Servicing
7.1 Maintenance
To avoid electrical shock, be sure that the power cord is disconnected before starting maintenance work.
EMC PARTNER recommends that the air filter of the ventilator be cleaned from time to time. The cleaning
cycle depends on the environmental conditions. Place the air filter of the ventilator in soapy water for 15
minutes . After 15 minutes, the air filter must be dried before being reinstalled.
If the DIPS and Variation circuit is used very often with high current, the VARIAC brushes must be
changed.
No further maintenance is necessary on the TRA3000 F-S-D-V-C.
7.2 Cleaning front and rearplate
The cleaning of the front-, rear- and type plate can be made with warm soapy water and a cleaning tissues.
The display can be cleaned with a cleaning tissues.
7.3 Verification versus Calibration
7.3.1 Verification Example IEC 61000-4-4 Ed.2
Set of operations which is used to check the test equipment system (e.g. the test generator and the
interconnecting cables) and to demonstrate that the test system is functioning within the specification given
in Clause 6
Note 1 the method used for verification may be different from those used for calibration
Note2 The procedure of 6.1.2 and 6.2.2 is meant as a guide to insure the correct operation of the test
generator, and other items making up the test set-up so that the indeed waveform is delivered to the EUT
Customer has to do it before a serie of tests starts
7.3.2 Calibration Example IEC 61000-4-4 Ed.2
Set of operation which establishes, by references to standards, the relationship which exists under specific
conditions, between an indication and a result of a measurement.
note 1 This terms is based on the “uncertainty” approach
Note2 The relationship between the indications and the results of measurements can be expressed, in
principle, by a calibration diagram.
7.4 Verification of the TRA3000 F-S-D-V-C by the user
A verification whether high voltage pulses occur at the tester outputs can be carried out using an
oscilloscope of a bandwidth of 20 MHz.
