Math Functions; Table 18 Command Sequence For Limit 2 Test Example - Keithley SourceMeter 2400 Series Quick Results Manual

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.
Comments
