Keysight Technologies AC6801B - Voltage Ranges and Limits

Voltage Ranges and Limits
The instrument has two voltage ranges: 155 V (low) and 310 V (high). It can also autorange between
the two ranges in AC or DC mode. The instrument will not switch voltage ranges (155 V, 310 V, or
AUTO), with the output on. If you attempt to do so, the output shuts off. Also, if you switch the range to
155 V when the voltage is set above 137.5 V the instrument sets the output voltage to 0 V.
Autoranging automatically switches to the 155 V or 310 V range according to the specified voltage. As
it does so, if the output is on, the instrument turns the output off for approximately 0.5 seconds and
turns it on again after the range switches.
The tables below indicate the output voltage setting ranges and maximum output current.
