sample rate from 24 to 50 measurements per second, 
depending on the current measurement mode used.

ALARM 
STATUS

Toggles alarm mode ON, OFF, or AUDIBLE.

ALARM HIGH

Sets the HI limit parameter. If the measurement exceeds 
this value, a red light will illuminate and the alarm will 
sound.

ALARM LOW

Sets the LOW limit parameter. If the measurement falls 
below this value, a red light will illuminate and the alarm will 
sound.
