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 to that the air filter of the ventilator from time to time be cleaned. 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.
No further maintenance is necessary on the MIG0603-Oxx.
7.2 Verification of the MIG0603-Oxx by the user
A simple verification whether high voltage pulses occur at the tester outputs can be carried out using an
oscilloscope of a bandwidth of 20 MHz.
7.2.1 Combination Wave Tester
Verification as specified in the Basic Standard 61000-4-5 for CWG.
•
Measurement of output voltage at no load
•
Measurement of short circuit current with short circuit output
•
Check that voltage and current waveform are within the tolerances.
•
Calculate the source impedance from the peak voltage divided by the peak current.
1. Setting „Main Menu“
V = 2000 V; Repetition 10s
2. Measuring point:
SURGE U-CRO for the voltage measurement at no load
SURGE I-CRO for current measurement at short circuit (make a short circuit on the EUT power output
phase to neutral on the front panel of the MIG0603OMX generator)
3. Settings at the oscilloscope
Time base 5 µs,
Vertical deflection 0.5 V / Division
Definition of the wave forms and their tolerances see chapter Insulation
7.2.2 Damped Oscillatory Wave tester
Verification as specified in the Basic Standard 61000-4-18.
1. Settings „Main Menu“
V = 16000 V; Repetition 10 s
2. Measuring point:
High voltage output measurement at no load
3. Setting of the oscilloscope
Time base 10 µs,
Vertical deflection 0.5 V / Division
Definition of the wave forms and their tolerances see chapter energy
