Chapter 4 Calibration Procedures<br />
Input Connections<br />
Input Connections<br />
You will need an input multiplexer module to verify or adjust the<br />
internal DMM. Input connections can be made using a 34901A<br />
20-Channel Multiplexer.<br />
To use a 34901A to completely verify and adjust the internal DMM,<br />
make the following connections:<br />
Connections for<br />
DC/AC Current<br />
Connections for<br />
4-wire Ohms<br />
Connections for DC V, AC V,<br />
2- and 4-wire Ohms<br />
Copper Short<br />
34901A<br />
To<br />
Calibrator<br />
Note: Use shielded twisted pair PTFE insulated cables to reduce<br />
settling and noise errors. Connect the shield to the source LO output.<br />
You can also use a 34902A for test and adjustment of voltage, frequency,<br />
and resistance functions. You cannot test or adjust current inputs with a<br />
34902A. If you use a 34902A, connect the copper shorts to Channels 7<br />
and 15 and make the input connections to Channels 8 and 16.<br />
