Button Function
• Measurement type selection
NOTE: The DC mode is activated by default
• Activates/Deactivates Auto-OFF at start-up (see § 3.3)
• Allows manual selection of a measurement range (short press)
• Returns to Auto-range mode (long press >2s)
NOTE: Continuity and Diode modes are not Auto-ranging
• Press once to activate the MAX/MIN mode; press >2s to exit
• Once activated, press to view the MAX, MIN and current value
NOTE: MAX mode is activated by default
• Freezes/Unfreezes the display of the measured value
(short press)
• Activates/Deactivates the display backlight (long press >2s)
• Displays the frequency of the AC signal measured, along with the
duty cycle
NOTE: This is inactive in DC mode
• Displays the value relative to a reference stored when the key was
pressed
Example: If the value stored when the key was pressed equals
10V and the current value is 11.5V, the display in relative mode
will be 11.5 - 10 = 1.5V.
