Ohms Measurements
4.
Select measurement range.
Using the RANGE

and

keys, select the lowest possible fixed range or use AUTO
range. Note that if sourcing current, you will be setting the voltage measurement range.
Conversely, if sourcing voltage, you will be setting the current measurement range. The
most sensitive measurement range provides the best accuracy.
NOTE
Measurement range is limited by the compliance setting. For example, if the voltage
compliance is 1V, (2V compliance range), the highest voltage measurement range
that can be selected is 2V.
5.
Turn output on.
Turn the output on by pressing the ON/OFF OUTPUT key. The OUTPUT indicator will
turn on to indicate the output is on.
6.
Observe reading on display.
The SourceMeter is in compliance if the Cmpl label or the units label (i.e. “mA”) for
the displayed compliance setting is flashing. If the Cmpl label is flashing, real compli-
ance has occurred. The output is clamped at the displayed compliance value. If the units
label is flashing, range compliance has occurred. The output is clamped at the maxi-
mum compliance value for the present fixed measurement range. For example, if pres-
ently on the 2V measurement range, a flashing units label for the voltage compliance
reading indicates that the output is clamped at 2.1V.
The SourceMeter can be taken out of compliance (real or range) by going into the edit
mode and decreasing the source value or increasing the compliance value. Note that
increasing the compliance limit may compromise protection for the DUT. If in range
compliance, selecting a higher measurement range may take the SourceMeter out of
compliance.
NOTE
See Section 5, “Compliance limit” for details on real and range compliance.
7.
Turn output off.
When finished, turn the output off by pressing the ON/OFF OUTPUT key. The
OUTPUT indicator light will turn off.
Ohms sensing
Ohms measurements can be made using either 2-wire or 4-wire sensing. See Section 2 for
details on sensing. Note that resistance measurement accuracy specifications are based on using
4-wire sensing.
