Setting the Voltage Range

The voltage range is switched with the OUTPUT turned off. The selectable voltage ranges are 135 V, 270 V, and AUTO..

The RANGE key is disabled when the OUTPUT is turned on.

The AUTO setting automatically switches between 135 V range and 270 V range.

AUTO cannot be selected in AC+DC mode, EXT-AC mode, or EXT-DC mode.

1	Press the OUTPUT key to turn the OUTPUT off. The LED above on the left of the OUTPUT key turns off.
2	Press the RANGE key (SHIFT+I) to select the voltage range. The range switches among 135 V, 270 V, and AUTO each time the key is pressed. The LED corresponding to the range illuminates. If the voltage is set above 137.5 V in the 270 V range or AUTO setting and the range is switched to 135 V, the output voltage is set to 0.0 V.
