Voltage Programming and Measurement Accuracy
This test verifies the voltage programming,
Action | Normal Result |
1.Turn off the dc source and connect a DMM to the output terminals.
2.Turn on the dc source with no load on the output. Set the output voltage to 0 V and the output current to full scale (see table
Output voltage near 0 V. Output current near 0 A.
3. | Record voltage readings at the DMM and on the front panel | Readings within low voltage |
| display in the appropriate table. | limits (see table |
4. | Set the output voltage to the full scale rated voltage | Output voltage near full scale. |
| (see Table |
|
5. | Record voltage readings at the DMM and on the front panel | Readings within high voltage |
| display in the table. | limits (see table |
Current Programming and Measurement Accuracy
This test verifies the current programming and measurement. Connect the appropriate current monitor (see table
Current Programming and Measurement (High Range)
Action | Normal Result |
1.Turn off the dc source and connect the DMM and current monitor as shown in figure
2. Turn on the dc source, access the Input menu, and set the current | CURR:DET DC |
sense detector to DC. |
|
3.Set the output voltage to 5 V and the current to 0 A. Press Output On/Off to enable the output.
Output current near 0 A.
4. | Divide the voltage drop across the current monitor by its | Readings within low current |
