Keysight 34401A
-DMM: Digital Multimeter
--
The 34401A is a 6.5 digit DMM that supports measurement of voltage, current, resistance and - frequency.
-Two-wire as well as four-wire measurements are possible.
-Temperature measurement was special order option and while there are ways to enable it, this - driver does not currently support it.

Supported devices: The driver has been tested with 34401A, 34410A, 34411A. Other versions of the 344xxA (e.g. 34465A) series that share the same SCPI commands should work as well.
The 34410A/34411A are 6.5 digit DMM that support measurement of voltage, current, resistance, capacitance, temperature, and frequency.
