• SW1: Kelvin/Non-Kelvin selection switch for High1
• SW2: Kelvin/Non-Kelvin selection switch for High2
• SW3: Kelvin/Non-Kelvin selection switch for Low
•SW4: 0 Ω/100 Ω series resistor selection switch for High2 Force
• SW5: Open/50 Ω shunt resistor selection switch between High2 and Low, Force
NOTE Selection switch SW2 and SW4
The SW4 switches the series resistance 0 Ω/100 Ω on the High2 Force line. The resistor is
not mounted on the High2 Sense line.
Set the SW4 to “0 Ω” if the SW2 is set to “Kelvin”.
Set the SW2 to “Non-Kelvin” if the SW4 is set to “100 Ω”.
NOTE Selection switch SW1/SW2/SW3
The switch is used to make or break the connection between Force and Sense in the
N1255A. Setting it to “Non-Kelvin” makes this internal connection to enable the
non-Kelvin connection. And setting it to “Kelvin” breaks this internal connection to enable
the Kelvin connection.
If the switch is set to “Non-Kelvin”, do not extend the Sense output corresponding to it.
Voltage on the Force line also appears on the Sense line. So, open the Sense connector on
the Output panel.
