FUNCTIONAL DESCRIPTION

FRONT PANEL

1. Liquid Crystal Display

2. SETUP key enters setup mode

3. CFM key confirms current choice (and skips to the next item)

4. CAL key initiates and exits calibration mode

5.  key 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

6. CAL DATA key last calibration data viewing (enters and exits)

7.  key 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

8. LCD key 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 710

models only, it switches between EC and TDS reading

9.  key moves to the next digit/letter (circular solution) when se-

lecting a parameter. Same as  key during last calibration

data viewing mode

10. LEDs
