FUNCTIONAL DESCRIPTION

FRONT PANEL

1. Liquid Crystal Display
2. LCD key

exits from setup and calibration modes and reverts back to
normal mode (in idle or control phases with the measure-
ment on the display). In pH 500 series, during pH
calibration, alternately displays pH buffer value or current
temperature

3. SETUP key

enters setup mode

4. CAL DATA key

last calibration data viewing (enters and exits)

5. CAL key

initiates and exits calibration mode

6.

 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

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.

 key

moves to the next digit/letter (circular buffer) when select-
ing a parameter. Same as   key during last calibration
data viewing mode

9. CFM key

confirms current choice (and skips to the next item)

10. LEDs
