CV Load Regulation, Volt | Agilent Technologies E3632A instruction

Chapter 3 Calibration Procedures

Constant Voltage (CV) Verifications

7Program the output voltage to full rated value (30.0V) by sending the command.

VOLT 30.0

8Record the output voltage reading on the digital voltmeter (DVM). The readings should be within the limits of (30V ± 25mV).

9Readback the output voltage over the remote interface by sending the command:

MEAS:VOLT?

10Record the value displayed on the controller. This value should be within the limits of (DVM ± 20mV).

CV Load Regulation

This test measures the change in the output voltage resulting from a change in the output current from full to no load.

1Turn off the power supply and connect a digital voltmeter between the (+) and (-) terminals of the output to be tested as shown in Figure 3-1.

2Turn on the power supply. Select the 30V/4A range, enable the output, and set the display to the limit mode. When the display is in the limit mode, program the output current to the full rated value (4.0A) and the voltage to the full rated value (30.0V)

3Operate the electronic load in constant current mode and set its current to 4.0A. Check that the front panel CV annunciator remains lit. If not lit, adjust the load so that the output current drops slightly until the CV annunciator lights. Record the output voltage reading on the digital voltmeter.

4Operate the electronic load in open mode (input off). Record the output voltage reading on the digital voltmeter again. The difference between the digital voltmeter readings in steps (3) and (4) is the CV load regulation. The difference of the readings should be within the limit of 5mV.

CV Line Regulation

This test measures the change in output voltage that results from a change in ac line voltage from the minimum value (10% below the nominal input voltage) to maximum value (10% above the nominal input voltage).

1Turn off the power supply and connect a digital voltmeter between the (+) and (-) terminals of the output to be tested as shown in Figure 3-1.
