last calibration data viewing (enters and exits)
exits from setup and reverts back to normal mode (in idle
or control phases with the measurement on the display).
During EC/TDS calibration, it alternates EC/TDS buffer
value and current cell constant on the display. In HI 24
series, it switches between EC and TDS reading
initiates and exits calibration mode
enters setup mode
moves to the next digit/letter (circular solution) when se-
lecting a parameter. Same as
data viewing mode
increases the blinking digit/letter by one when selecting a
parameter. Advances forward while in last calibration
data viewing mode. Increases the temperature setting
when temperature probe is not inserted
confirms current choice (and skips to the next item)
decreases the blinking digit/letter by one when selecting
a parameter. Reverts backward while in last calibration
data viewing mode. Decreases the temperature setting
when temperature probe is not inserted
