36 Quick Results Guide
Programming example
The programming example in Table 18 tests 1kΩ resistors. If the tested resistor is within 5%
of it’s nominal value, it will pass the test. Otherwise the test will fail.
Math functions
The SourceMeter has five built-in math functions; power, offset compensated ohms, varistor
alpha, voltage coefficient and percent deviation. After a math function is configured and
enabled, it can be selected by pressing the FCTN key (MATH annunciator displayed).
Power
Calculates and displays power using the measured voltage (V) and measured current (I) val-
ues as follows:
Power = V × I
Use the following menu sequence to enable the power math function:
Press CONFIG > press FCTN > select POWER
This math function can now be selected by pressing the FCTN key.

Command sequence for Limit 2 test example
Command* Comments
*RST Restore GPIB defaults.
:SENS:FUNC “RES” Select ohms meaurement function.
:CALC2:LIM2:STAT ON Enable Limit 2 test.
:CALC2:FEED RES Use ohms for limits comparison.
:CALC2:LIM2:LOW 950 Set lower limit to 950Ω.
:CALC2:LIM2:UPP 1050 Set upper limit to 1050Ω.
:OUTP ON Turn output on.
:INIT Trigger reading.
:CALC2:LIM2:FAIL? Query result of Limit 2 test (0 = pass, 1 = fail).
:OUTP OFF Turn output off.
*SourceMeter must be addressed to talk after sending :CALC2:LIM2:FAIL? to acquire test result.
