M2 Scope/Meter Operations
Brief explanations of the soft key functions are provided below, refer to
on page 91 for
more detailed descriptions.
F1 Key
The F1 key switches between normal and relative readings. A short push of the key resets the
reading, a long push opens the alternate menu.
F2 Key
A single press of the F2 key pauses, or freezes, the displayed value. A second press returns the
display to normal mode.
F3 Key and Range Key
The F3 and Range keys select the measurement range, which varies with the selected function:
•
Current—switches the scale between available settings for AC Amp and DC Amp probes.
•
Temperature—switches between displaying degrees Celsius and degrees Fahrenheit.
•
Pressure—switches between displaying pressure as pounds-per-square-inch (PSI) and
vacuum as inches-of-mercury (inHg).
F4 Key
The F4 key is nonfunctional in this mode.
S Key
The S key is used to switch between the three different test modes (amperage, temperature, and
pressure) available in the auxiliary setting. Each key press advances to the next available 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.
Graph Key
Pushing the Graph key generates a histogram that graphically shows the various values of the
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 “Auxiliary” function.
