signal. The readouts or display changes depending on the measurement or analysis mode.
4. Measurement status. Shows the math or limit testing mode (MATH or LIM), the m easure status (MEAS, HOLD, or SING),

associated limit value. An emoticon icon shows the relative measurement value and limit pass/fail state (a sm iling face
