Remarks
The range and resolution are fixed for diode tests: The range is 1 Vdc (with
a 1 mA current source output).
The voltage is displayed on the front panel if it is in the 0 to 1.2 volt
range. The meter beeps when the signal transitions to the 0.3 to 0.8 volt
threshold (unless beep is disabled). If the signal is greater than 1.2 volts,
"OPEN" is displayed on the front panel.
The FETCh?, READ?, and MEASure:DIODe? commands return the
measured voltage, regardless of its value.
