See Figure 5-39 and Figure 5-40.CAUTIONHigh potential test equipment must not be used. Use of such equipment may destroy thesemiconductors In current boost module A 101.(1)Connect a 0 to 300 volt AC variable power supply with voltmeter, and ampermeter that has a five ampcapacity across terminals 1 and 2, and a load resistor in series such as 500 watt 240 volt light bulb. Alsoconnect another like power supply to terminals 3 and 4 of current boost module A101.(2)Connect a DC voltmeter and load (such as a 240 volt 500 watt light bulb) to terminals N and P of currentboost module A101.(3)Turn on power supply to terminals 3 and 4 then adjust voltage to 240 VAC. Rotate operation point adjustcontrol R13 to just turn out operation point indicator (LED). Lower power supply voltage to 200 VACoperation point indicator should light.5-93
