Navigation M2 Data Acquisition Device Controls and Features
Figure 4-1 Sample Rotary Selector Switch
The available functions are represented by graphic icons on the face of the tool. Descriptions of
the functions are given in the following table:
Table 4-2 Data Acquisition Device rotary switch settings
Function Icon Description
Off
Switches power to the M2 unit off. The switch should be in
this position whenever the tool is not being used to prevent
battery drain.
Volts DC
Measures direct current (DC) voltages within a range of zero
to 600 volts. This setting is also used to measure frequency
(hertz), duty cycle (%), and time period (cycle, ms).
Volts AC
Measures alternating current (AC) voltages within a range of
zero to 1000 volts. This setting is also used to measure
frequency (hertz), duty cycle (%), and time period (cycle, ms).
Resistance
Measures the DC resistance to current in ohms in a range of
zero to open circuit (infinite).
Continuity/
Diode Check
Performs dual tests; circuit continuity and diode test (forward
drop). The “S” (special function) soft key switches between
the two tests.
Auxiliary
Performs three auxiliary tests; current (amperes), pressure,
and temperature. The “S” (special functions) soft key
switches between the three tests. Pre-approved sensors
must be used in order to take valid measurements.
Capacitance
Measures capacitance in nanofarad (nF), millifarad (mF), and
microfarad (µF).
Oscilloscope
(Waveform Viewer) Configures the M2 unit to perform as one or two channel
oscilloscope, or waveform viewer.
Remote Functions
Configures the M2 unit to be operated through the Display
Device. Readings are also shown on the Display Device
screen. All of the controls on the from panel of the M2 unit
become inoperative when the rotary switch is in this position.
