10) CAL key:
If pressed during calibration,
the calibration procedure will
be aborted and the last cali-
bration data will be retrieved.
If pressed together with the
ALT key for less then 3 sec-
onds, the diagnostic mode will
be entered.
If pressed together with the
ALT key again, the meter will
quit diagnostic mode.
If pressed for more then 3
seconds, a blinking “CAL” will
appear and the calibration
procedure is entered.
11) GLP/Abs key: In ion specific mode, it will
toggle concentration/absor-
bance readings on main LCD.
In turbidity mode, GLP data
(date, time and the 2 calibra-
tion values) will be shown.
If pressed in time/date setup
mode, the meter will quit cur-
rent mode without making any
change.
12) key
Scrolls upwards through the
parameters to be measured.
In calibration and diagnostic
modes, increments the blink-
ing digit by one.
If pressed together with ALT
while the meter is in logging
mode, the upper LCD will
show the stored data (date,
time, value).
13) ALT key:
Activates alternative functions.
14) key:
Scrolls downwards through the
parameters to be measured.
2) Secondary LCD:
The three-digit lower level shows the cur-
rent measurement mode (“F CL”, “t CL”, or
“tr”), and diagnostic or calibration modes,
such as “d 11”, “2 Fn”, “5 c1”.
3) DATE:
Indicates that the main LCD
is showing the current date,
the date of last calibration or
the date of logged measure-
ment in memory.
4) TIME:
Indicates that the main LCD
is showing the current time,
the time of last calibration or
the time of logged measure-
ment in memory.
5) LOBAT:
Blinks to warn the user of low
battery voltage.
6) LOG:
Blinks to indicate that the
meter is in the scroll mode
viewing the logged data.
If fixed, it indicates that the
meter is in the log mode and
every reading will be stored
in memory.
7) ON/OFF key:Turns the meter on and off.
8) ZERO /
key: In ion specific mode, it ze-
ros the sample.
In calibration and diagnostic
modes, it works as ENTER.
In turbidity mode, it is not
used.
9) READ /
key: Takes concentration/tur-
bidity measurement of the
sample.
In diagnostic or calibration
mode, shifts the flashing digit
to the right.
