Agilent Technologies E3632A guide

115V/7A range selection key Selects the 15V/7A range and allows the full rated output to 15V/7A.

230V/4A range selection key Selects the 30V/4A range and allows the full rated output to 30V/4A.

3Overvoltage protection key Enables or disables the overvoltage protection function, sets trip voltage level, and clears the overvoltage condition.

4Overcurrent protection key Enables or disables the overcurrent protection function, sets trip current level, and clears the overcurrent condition.

5Display limit key Shows voltage and current limit values on the display and allows knob adjustment for setting limit values.

6Recall operating state key Recalls a previously stored operating state from location ‘‘1’’, ‘‘2’’, or ‘‘3’’.

7Store operating state / Local key1 Stores an operating state in location ‘‘1’’, ‘‘2’’, or ‘‘3’’ / or returns the power supply to local mode from remote interface mode.

8Error / Calibrate key2 Displays error codes generated during operation, self-test and calibration / or enables calibration mode (the power supply must be unsecured before performing calibration). See Service Guide for more details on calibration.

9I/O Configuration / Secure key3 Configures the power supply for remote interfaces / or secure or unsecure the power supply for calibration. See Service Guide for more details on how to secure or unsecure the power supply.

10Output On/Off key Enables or disables the power supply output. This key toggles between on and off.

11Control knob Increases or decreases the value of the blinking digit by turning clockwise or counter clockwise.

12Resolution selection keys Move the blinking digit to the right or left.

13Voltage/current adjust selection key Selects the knob control function for voltage or current adjustment.

1The key can be used as the ‘‘Local’’ key when the power supply is in the remote interface mode.

2You can enable the ‘‘calibration mode’’ by holding down this key when you turn on the power supply.

3You can use it as the ‘‘Secure’’ or ‘‘Unsecure’’ key when the power supply is in the calibration mode.
