All test conditions can be set and displayed only on 1 to 2 screens. High operability is realized in combination with the chassis design taken the user-friendliness into account. MANUAL mode Test conditions setting IEC (Test level) mode SWEEP mode MANUAL mode screen which is used most frequently. Since Histogram is also displayed, setting of tests conditions can be seen intuitively Selectable test conditions like the polarity switching are set by ON/ OFF of the buttons. s as numerical setting can be easily input with the ten-key which is displayed by touch onto the screen. Tests conditions defined by IEC is preset. In the injection to power supply lines, the presets are the output voltages (0.5kV, 1.0kV, 2.0kV and 4.0kV) and the burst frequency (5kHz / 100kHz) A test mode to preset the output voltage and variation of the burst frequency, and automatically perform the test. The voltage variation is set from 500V to 2500V per 250V step. This is efficient function to judge malfunction point of EUT and can also set variation of conditions for the output voltage, burst frequency, polarity, injection phase.
