The '''Keithley 195A''' is a 5½-digit LED True-RMS, auto-ranging digital multimeter.  It features a standard GPIB interface.  Current and True RMS ranges are optional (Opt. 1950).
The '''Keithley 195A''' is a 5½-digit LED True-RMS, auto-ranging digital multimeter.  It features a standard GPIB interface.   
Current and True RMS ranges are optional (Opt. 1950).
If option 1950 is installed, two jumper wires (zero-ohm resistors), W102 and W103 are to be removed from the circuit.
