36 Quick Results Guide
Programming example
The programming example in Table 18 tests 1k 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)
values 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.
