EASUREMENTS
To make a measurement, select to proper range and engage the Test
Current. Always be sure to disengage the Test Current after each
measurement or before disconnecting the load and/or leads from the
instrument.
The 4300C has 3 voltage settings and 6 current ranges. The combination
of the two result in 16 possible resistance measurement ranges. (See
table 7).

1A 2) 20mΩ
.1A 3) 200mΩ
10mA 4) 2Ω
1mA 5) 20Ω
.1mA 6) 200Ω
The two keys labeled F.S. Voltage are used to change the voltage setting.
The  key is used to increase the voltage setting and the  key is used to
decrease the setting.
Within a voltage setting there are six possible Ohm Ranges. The two keys
labeled Ω Range are used switch between the ranges. The  key is used
to increase the range and the  key is used to decrease the range. As the
Ohms range increases, the current range decreases and vice versa.
To engage or disengage the Test Current press the Test Current key
located on the front panel. A red LED within the Test Current key
indicates the status of the current source.
The current source may also be turned on and off via a command from
one of the interfaces, or by a remote footswitch using Option "RS".
