M2 Scope/Meter M2 Scope/Meter Controls, and Features
8.2.1 Rotary Selector Switch
The M2 Scope/Meter is a combination digital-multimeter (DMM) and waveform viewer, capable of
reading volts (AC and DC), resistance (ohms), capacitance (farads), continuity, diode forward
voltages, and external auxiliary probes, as well as viewing dynamic voltage graphs (waveforms).
The Rotary Selector Switch on the front panel determines which measurements are taken.
The available functions are represented by graphics on the face of the tool. Descriptions of the
functions are given in the following table:
Table 8-1 M2 Scope/Meter rotary switch settings
Function Icon Description
Off
Switches power to the M2 Scope/Meter off. The
switch should be in this position when the tool is
not being used to prevent battery drain.
Volts DC
Measures direct current (DC) 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). See Volts DC
on page 91.
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). See
Volts AC on page 95.
Resistance
Measures the DC resistance to current in Ohms
in a range of zero to open circuit (infinite). See
Resistance on page 97.
Continuity/
Diode Check
Performs dual tests; circuit continuity and diode
test (forward drop). The “S” (special function)
soft key switches between the two tests. See
Continuity and Diode Check on page 98.
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. See
Auxiliary on page 98.
Capacitance
Measures capacitance in nanofarad (nF),
millifarad (mF), and microfarad (µF). See
Capacitance on page 100.
Oscilloscope
(Waveform Viewer)
Configures the M2 Scope/Meter to perform as
one or two channel oscilloscope, or waveform
viewer. See Oscilloscope on page 101.
Remote Functions
Configures the M2 Scope/Meter to be
connected wirelessly to a Diagnostic Tool. The
display is transmitted to the Diagnostic Tool
screen. All soft key controls on the M2 Scope/
Meter are inoperative when the rotary switch is
in this position. See Remote Functions Setting
on page 107.
