Ohms Measurements
Enabling/disabling offset-compensated ohms
Offset-compensated ohms is enabled or disabled from the OFFSET COMPENSATION
option of the CONFIG OHMS menu as follows:
1.
Press CONFIG and then
Ω
to display the ohms configuration menu.
2.
Place the cursor on OFFSET COMPENSATION, and press ENTER.
3.
Place the cursor over ON (to enable compensation) or OFF (to disable compensation),
and press ENTER.
4.
Use the EXIT key to exit the menu structure.
Offset-compensated ohms procedure
NOTE
The following procedure assumes that the desired ohms measurement method (auto
or manual) is already selected and the SourceMeter is connected to the DUT as
explained in Section 2. Refer to “Selecting ohms measurement method” to check or
change the measurement method.
1.
Turn the output off and select the
Ω
measurement function.
2.
If measuring high resistance, set an adequate source delay (see
Measuring high resis-
tance devices
). Source delay is set from the source configuration menu (press
CONFIG > select SOURCE I (or V) > select DELAY). See Section 3,
Source delay
for
details.
3.
Enable offset compensation as previously explained in
Enabling/disabling
offset-compensated ohms
.
NOTE
If using the auto ohms measurement method, go to step 5.
4.
For manual ohms measurements, configure the desired source (V or I) to output the
appropriate source level. Set compliance and select a measurement range (or use AUTO
range). See steps 1, 2, and 3 of Section 3,
Basic source-measure procedure
for details.
5.
Turn the output on, and observe the offset-compensated ohms reading on the display.
Note that the source alternates between the programmed output value and zero.
NOTE
When the output is turned off, the displayed source value may be zero (0V or 0A). It
will usually be the previously programmed value in Manual Ohms mode. However,
the programmed source value is remembered and used when the output is turned
back on. If a new source value is programmed, the SourceMeter uses the new source
value when the output is turned back on. The source value cannot be changed while
the output is on. If a global setup or source memory location is saved, the previously
programmed source value will always be stored.
6.
When finished, turn the output off, and disable offset-compensated ohms.
