Sense and guard selections

NOTE When sense or guard settings are changed, the OUTPUT will turn OFF.

Sense selection

When using the SENSE HI and LO terminals of the SourceMeter, 4-wire remote

sensing must be selected. When not using these terminals, local sensing must be

selected. Sense selection is explained as follows. See Section 3, “Operation over-

view,” for details on sense.

NOTE The SourceMeter defaults to the 2-wire (local) sense mode when the out-

put is off, regardless of the sense setting. When the output is turned on,

the present sense setting will be in effect.

Front panel sense selection

On power-up, the instrument is automatically set for 2-wire local sense. Perform

the following steps to check and/or change the sense selection:

1. Press CONFIG and then the SOURCE V, MEAS V, or Ω key. Changing

sense in one configuration menu changes it in all of the others.

2. For SOURCE V and Ω, use the ß and © keys to place the cursor (flashing

menu item) on SENSE MODE and press ENTER.

NOTE Cursor position indicates the present sense selection. Two-wire indicates

that local sense is selected, and 4-wire indicates that remote sense is

selected. To retain the present selection, use the EXIT key to back out of

the menu structure and skip the next two steps.

3. To change the sense selection, place the cursor on 4-wire to select remote

sense or on 2-wire to select local sense, and press ENTER.

4. Use the EXIT key to back out of the menu structure.

Remote command sense selection

Use the :SYSTem:RSENse command (Section 18, “SYSTem subsystem”) to

choose between local and remote sensing via remote. For example, send the fol-

lowing command to enable remote sensing:

:SYST:RSEN ON

Conversely, send this command to disable remote sensing (enable local sensing):

:SYST:RSEN OFF
