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 502 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
