M2 Data Acquisition Device
Digital Multimeter Operations
F3 Key
Short pushes of the F3 and Range keys incrementally increase and decrease the selected
measurement range respectively. These keys are active in both the standard Volts AC and
histogram modes.
F4 Key
The F4 key is nonfunctional in this mode.
S Key
Pressing the S key activates the time management functions to display frequency, duty cycle, and
pulse width. A long press of the key returns to the normal display mode.
Min/Max Key
Pressing the Min/Max key causes minimum and maximum readings to display along with the
current value. A long press of the key returns to the normal display mode.
Range Key
A press of the F3 or Range keys changes the voltage scale or resolution of the display. Each key
press incrementally advances through the available settings. A long press of the Range key
returns to display to the automatic range.
Graph Key
Pushing the Graph key generates a histogram that graphically shows the various values of the
voltage measurements taken.
The Range and F3 keys can be used to change the measurement range. When Range is pressed,
the current histogram erases and a new graph starts building from zero.
Pressing the F4 and Graph keys while in Graph mode changes the sweep rate, or the time
represented by the width of the screen.
A “long press” of the “Graph” key returns the unit to the normal “Volts AC” function.
8.2.3 Resistance
This setting allows you to measures the DC resistance to current in ohms. When sampling
resistance the soft keys function much the same as for DC or AC voltage. Brief explanations are
provided below, refer to
for more detailed descriptions.
