Button Functions on the Amprobe AM-250

Getting comfortable with the Amprobe AM-250 didn’t take long. I quickly realized how each button helps streamline my testing routine especially when precision and speed matter most. These buttons aren’t just extras; they’ve become part of how I work in the field.

• SELECT Button
  This button allows me to switch between different measurement modes within a single dial setting. For instance, when measuring current, I can toggle between AC and DC modes. Holding the SELECT button for more than a second activates the backlight, which is especially useful in dimly lit areas.
• HOLD Button
  Pressing the HOLD button freezes the current reading on the display. This feature is handy when I need to record a measurement without the value changing.
• MAX Button
  The MAX function captures and displays the highest reading detected. This is particularly useful when monitoring fluctuating signals, as it allows me to identify peak values over time.
• RANGE Button
  By default, the multimeter operates in auto-ranging mode. However, pressing the RANGE button allows me to switch to manual-ranging mode, giving me control over the measurement range. Holding the button for more than a second returns the meter to auto-ranging mode.
• REL (Relative Zero Mode) Button
  The REL function lets me set a reference point for measurements. This is helpful when I want to measure variations from a known baseline, such as checking voltage drops across components.
