M2 Scope/Meter Operations
NOTE:
i
Press and hold the S key at any time to instantly return the display to a voltage reading.
In this special time measurement mode, the readings shown on the screen are integrated, or
filtered. This means that the displayed values show average time-based measurements with great
accuracy, but do not capture fast signal anomalies such as instantaneous “glitches” or timing
shifts. However, these types of fast signal changes can be seen using the Graph key.
Graphing Voltage Measurement Screens
The M2 Scope/Meter can generate a graphical history of a voltage signal over time, which is called
a histogram. Pressing the Graph button when operating in Volts DC or Volts AC range causes the
display to change from a digital reading to a graphical display.
While viewing a histogram, the function keys operate as follows:
•
F1
—switches peak detection on and off
•
F2
—freezes and unfreezes the histogram (pauses and resumes data collection).
•
F3
—incrementally increases the measurement range. The
Range
key incrementally
decreases the measurement range.
•
F4
—incrementally increases the timescale of the histogram. The
Graph
key incrementally
decreases the timescale.
A digital value of the signal displays in the upper-right corner of the display while operating in
graphing mode.
Graphing with Min/Max Function
In the Volts DC graphing function you can capture and store the minimum and maximum voltages
by pressing the Min/Max soft key. The readings appear in the upper-left portion of the LCD. The
M2 Scope/Meter captures and reports very fast events (as fast as 50 microseconds) in this mode,
which is only available in Volts DC.
Press the Min/Max key and the display shows both the instantaneous voltage reading (large
characters) and the minimum and maximum voltages that occurred since the last time the key was
pressed. The displayed values continue to update until the “Min/Max” key is pressed again. Then
the values reset the readings on the display begin the process again. Press and hold the Min/Max
key to cancel this function, and return to the normal volts DC mode.
