| Instrument Accuracy Test |
| Procedure |
| The following procedure should be performed for the Instrument Accuracy |
| Test. |
|
|
Note | The procedure details the key presses required on the |
| Agilent E4418B. For the Agilent E4419B the equivalent key |
| presses should be performed on both channels. |
|
|
| 1. Connect the equipment as shown in Figure |
| 2. Unplug the range calibrator's power cord. Due to a ground loop |
| design problem with the 11683A option H01 range calibrator, it |
| will not operate properly unless ground loops are eliminated. The |
| instrument will continue to operate with no power applied, and |
| disconnecting the power cord eliminates the problem. |
|
|
WARNING | There is a small risk of mild electrical shock from the |
| chassis of the 11683A option H01 range calibrator unless |
| the power meter is connected. |
