KEY
DESCRIPTION
RANGE
The RANGE button is used to change the voltage range
between the low range (0 to 135 volts) and high range (0 to
270 volts). The LED above the switch will light to indicate
the high voltage range selection. The output voltage will be
reset to zero voltage after a range change.
OUTPUT
The OUTPUT button will toggle the output to enable or
disable the output. The LED above the button will light when
the output is on. No output voltage will be present when the
OUTPUT button is off despite the level of voltage
programmed.
MODE
The MODE button selects the function of the right shuttle
knob and the right LED segment display. The shuttle will
control the output frequency and the display will show the
program frequency value when the mode selection is
frequency. The Shuttle knob will program the current limit
and the display will show its value in the current mode. The
display will revert back to showing the measured current
after 3 seconds from the last movement of the shuttle. The
measurement is updated 4 times per second. The display
mode is indicated by the two LED‟s above the LED segment
display.
