The load resistor must have a voltage rating of at least 250V, and a power rating of at
least 50 Watts. It must also be low-inductance, or the waveform will become distorted
and exhibit noticeable ringing.
BASIC TEST ARRANGEMENT - WITH OUTPUT MODULE
To fully test the instrument, and for normal operation, the output module must be
connected as shown below:
If a Tektronix CT2 current probe or Pearson 2878 current transformer is not available to
measure the output current waveform, or the output pulses are too wide, a 1 Ohm
resistor may be used to sense the current instead. However, noticeable ringing and
