Front-Panel Voltage and Current Limit Settings
You can set the voltage and current limit values from the front panel using the
following method.
1Select the desired range using the range selection keys after turning on the
power supply.
2Press the #key to show the limit values on the display.
3Move the blinking digit to the appropriate position using the resolution
selection keys and change the blinking digit value to the desired voltage limit
by turning the control knob. If the display limit times out, press the key
again.
4Set the knob to current control mode by pressing the key.
5Move the blinking digit to the appropriate position using the resolution
selection keys and change the blinking digit value to the desired current limit
by turning the control knob.
6Press the #key to enable the output. After about 5 seconds, the display
will go to output monitoring mode automatically to display the voltage and
current at the output or the display will go to output monitoring mode
immediately by pressing the #key again.
Note All front panel keys and controls can be disabled with remote interface commands.
The HP E3633A and HP E3634A must be in "Local" mode for the front panel keys
and controls to function.
Use thevoltage/current adjustselection key,the resolution selectionkeys,
and the control knob to change the voltage and current limit values.
