3.5.6 Output voltage monitoring
Output voltage: An output voltage can be monitored by using the monitor output connector on the rear
panel and the output LED meter on the front panel.
Output voltage: An output current can be monitored by using the output LED meter on the front panel.
 Monitor output connector
An output waveform can be observed by connecting an oscilloscope directly.
A waveform is output on the monitor output connector, regardless of the output on/off setting. A
voltage with the level corresponding to 1/100 of the main output level is output.
 Output LED meter
With 11 LEDs, the level of 0% to 100% is displayed with the output voltage full scale of 75 V and the
output current full scale of 1.06 A as 100%. The output meter is calibrated so that an RMS value is
shown for a sine wave according to the full-wave rectified average detection method.
An average value is shown when an AC is superimposed on a DC. Examples are provided below.

When a sine wave of 5 Vrms is superimposed on a DC of +10 V: Level of 10 V is shown.

When the DC level is zero, and a sine wave of 5 Vrms is given: Level of 5 V is shown.
A polarity is shown by a meter polarity LED. The meter polarity LED for "+" turns on when positive
voltage/current is output. The LED for "

" turns on when negative voltage/current is output. Both
LEDs are turned on for an AC output voltage. The LEDs turn on alternately for a low frequency.
