M2 Data Acquisition Device Digital Multimeter Operations
Figure 8-8 Continuity and diode check selected
The S key is the only soft key that is operational in continuity and diode mode. Pressing the S key
switches between the continuity test and diode test settings. Continuity is the default setting.
When testing continuity, the M2 unit sounds a beep if a short circuit is detected (continuity between
the two test leads).
When testing a diode, the M2 unit induces a current to the device under test and measures the
resultant voltage drop across the device.
8.2.5 Auxiliary
This selection allows you to select between three auxiliary tests; current (amperes), temperature,
and pressure. Approved probes, sensors, and transducers must be used in order to obtain valid
measurements.

Brief explanations of the soft key functions are provided below, refer to "Volts DC‚" on page 69 for
more detailed descriptions.
