meter will quit diagnostic mode. If pressed
for more then 3 seconds, an intermittent
“
CAL
” prompt will appear on the
upper LCD level and the calibration
procedure is entered.
11)
GLP/Abs
key:
In ion specific mode, it will toggle
concentration/absorbance readings on the
upper LCD. In turbidity mode, date,
time and the two calibration values of
the current mode will be shown. If
pressed in time/date setup mode, the
meter will quit current mode without
making any changes to current time/
date.
12) key
Scrolls upwards through the parameters
to be measured. In calibration/diagnostic
mode, increments the blinking digit by
one. If pressed together with
ALT
while
the meter is in logging mode, the upper
LCD will show the data (date/time/
value) in the memory.
13)
ALT
key:
Alternative functions.
14) key:
Scrolls downwards through the parameters
to be measured. In calibration/diagnostic
mode, decreases the blinking digit by
one. If pressed together with
ALT
while
the meter is in logging mode, the upper
LCD will show the current lot number.
2)
Secondary
LCD
:
The three-digit LCD shows the current
mode of measurement that is “
F CL
”,
“
tCL
”, “
CY
”, “
PH
”, “
Id
”, “
Br
”, “
LFE
”,
“
tr
”, and diagnostic or calibration modes,
such as “
d11
”, “
2 Fn
”, “
5c1
”.
3)
DATE
:
Indicates that the upper level of LCD is
showing the current date, the date of
last calibration or the date of logged
measurement in memory.
4)
TIME
:
Indicates that the upper level of LCD is
showing the current time, the time of
last calibration or the time of logged
measurement in memory.
5)
LOBAT
:
Blinking segment warns user of low
battery voltage.
6)
LOG
:
If intermittent, it indicates that the user
is in the scroll mode viewing the logged
measurements. If fixed, it indicates that
the meter is in the log mode and every
reading taken will be stored in memory.
7)
ON/OFF
key:
Turns the meter on and off.
8)
ZERO /
key:
In ion specific (colorimetric) mode, it
zeros the sample. In calibration and
diagnostic modes, it functions as ENTER
(not used in turbidity mode).
9)
READ /
key:
Takes the measuremnt of concentration/
turbidity of the sample which is shown
on the LCD. In diagnostic or calibration
mode, shifts the flashing digit to the
right.
10)
CAL
key:
If pressed during calibration, the
calibration procedure will be aborted
and the last calibration data will be
reinstated. If pressed together with the
ALT
key for less then 3 seconds, the
diagnostic mode will be entered. If pressed
together with the
ALT
key again, the
