BYKLC3 Mains power

Mains power
You can either operate the measuring instrument with batteries or with the
plug-in power supply. The plug-in power supply provides the measuring in-
strument with low voltage (7.5 V ... 12 V DC). This saves the batteries.
Warning
The line voltage at the operating site must lie within the input voltage range
of the original plug-in power supply (see TECHNICAL DATA).
Warning
Only use original plug-in power supplies (see TECHNICAL DATA).
Switching on the measuring instrument

!Plug the jack (1) into the socket (2) of the measuring instrument.
!Connect the original plug-in power supply (3) to an easily accessible
mains socket.
!Press the <>key.
Display test appears briefly on the display.
After this, the measuring instrument automatically switches to the mea-
suring mode. The display shows the relevant measured value.

Measuring BYK LC 3

Measuring
Overview of the measuring modes:
Special functions:
AutoRead
(drift control)
The AutoRead function checks the stability of the measurement signal (ex-
cept for the measurement of the ORP voltage). Activate AutoRead with
<AR>. Press <RUN/ENTER> to start the AutoRead measurement. During
the AutoRead measurement, AR flashes on the display until a stable mea-
sured value is reached. This can be terminated at any time taking over the
current measured value with <RUN/ENTER>.
AutoRange
measuring range
selection
There are several measuring ranges available for conductivity measure-
ments. If a measuring range is exceeded, AutoRange causes the measuring
instrument to change automatically to the next measuring range. When the
AutoRange function is switched on, ARng appears on the display.
Temperature
measurement
The measuring instrument automatically measures the temperature of the
sample with the integrated temperature sensor of the conductivity measuring
cell (display TP). In measuring cells without temperature sensors, the tem-
perature can be entered manually with <▲> <▼>.
Factor for
dry filtrate residue
The factor for determining the dry filtrate residue is freely selectable in the
range 0.40 to 1.00. TDS is also displayed in the measuring mode as well as
the measured value. The factor can be changed if necessary with <▲> <▼>.
Temperature
compensation
You can select from the following settings:
!Nonlinear temperature compensation (nLF) according to EN 27 888
!Linear temperature compensation (Lin) with selectable coefficients of
0.001 ... 3.000 %/K
!No temperature compensation (- - - -)
Press <CAL> until tc appears to set the temperature compensation. Then,
confirm with <RUN/ENTER>. Select the required option with <CAL>.
If necessary, select the temperature coefficients with <▲> <▼>. Return to the
measuring mode with <M>.

BYK LC 3 Determining/Setting the cell constants

Determining/Setting the cell constants
Procedure The cell constants are determined in the control standard, 0.01 mol/l KCl.
You can determine the cell constants of the conductivity measuring cells in
the range of 0.450 ... 0.500 cm-1 or 0.800 ... 1.200 cm-1 .
You can also set the cell constants manually in the ranges
!0.090 ... 0.110 cm-1
!0.250 ... 2.500 cm-1
or select the fixed cell constants 0.010 cm-1.
Calibration
evaluation
After the calibration, the measuring instrument automatically evaluates the
current status of the calibration. The evaluation appears on the display.
Procedure for determining the cell constants:
Display Cell constant [cm-1]
0.450 ... 0.500 cm-1
0.800 ... 1.200 cm-1
E3
Invalid calibration
Outside the range
0.450 ... 0.500 cm-1
or
0.800 ... 1.200 cm-1
!Connect a conductivity measuring cell to the measuring instrument.
!Press the <CAL> key repeatedly until the CELL display appears.
!Then press the <RUN/ENTER> key.
!Press the <CAL> key repeatedly until the CAL appears. Depending
on the calibration status, the instrument displays:
–the current, calibrated cell constant (with sensor symbol on the
display) or
–the fixed cell constant 0.475 1/cm (without sensor symbol on the
display). In this case, the measurement parameters are initialized.
Note
At this point, the procedure can be terminated with <M>.
!Immerse the conductivity measuring cell in the control standard solution,
0.01 mol/l KCI.

Saving data
Saving data
manually
Press the <STO> key in the measuring mode (display No. with the number of
the next free memory location). Then press <RUN/ENTER> and enter the ID
number with <▲> <▼>. Terminate the save with <RUN/ENTER>. The instru-
ment changes to the measuring mode.
Saving data
automatically Int 1
The portable measuring instrument BYK LC 3 has an internal data memory.
It can store up to 800 datasets. The save interval (Int 1) determines the chro-
nological interval between automatic save processes.
To set up the save interval, press <STO> while pressing the <RUN/ENTER>
key (display Int 1) and set the interval with <▲> <▼>key . Then, press
<RUN/ENTER> and enter the ID number with <▲> <▼>. Change to the last
active measuring mode with <RUN/ENTER>. The automatic save is switched
on (display Auto Store).
Outputting the data memory
You can output the data memory with the <RCL> key. By repeatedly press-
ing the <RCL> key, you reach the following functions:
Start the output with <RUN/ENTER>.
Transmitting data
Transmitting data
manually
Press the <RUN/ENTER> key in the measuring mode.
This manually triggers a data transmission of the current measured value to
the serial interface at any time - independently of the selected intervals.
Transmitting data
automatically Int 2
The interval to the data transmission (Int 2) determines the chronological in-
terval between automatic data transmissions. After the selected interval ex-
pires, the current data record is transmitted to the interface. To set up the
transmission interval, press <RCL> while holding down the <RUN/ENTER>
key (display Int 2). Then, set the interval with <▲> <▼>.

Netzbetrieb
Sie können das Messgerät wahlweise mit Batterien oder mit dem Stecker-
netzgerät betreiben. Das Steckernetzgerät versorgt das Messgerät mit Klein-
spannung (7,5 V ... 12 V DC). Die Batterien werden dabei geschont.
Achtung
Die Netzspannung am Einsatzort muss innerhalb des Eingangs-Spannungs-
bereichs des Original-Steckernetzgeräts liegen (siehe TECHNISCHE DATEN).
Achtung
Verwenden Sie nur Original-Steckernetzgeräte (siehe TECHNISCHE DATEN).

Messen
Überblick über die Messmodi:
Spezialfunktionen:
AutoRead
(Driftkontrolle)
Die Funktion AutoRead prüft die Stabilität des Messsignals. AutoRead mit
<AR> aktivieren. Der aktuelle Messwert wird eingefroren. Daher kann die Ta-
ste <AR> auch als "Hold-Funktion" zum Einfrieren von Messwerten verwen-
det werden. Zum Starten der AutoRead-Messung <RUN/ENTER> drükken.
Während der AutoRead-Messung blinkt die Anzeige AR, bis ein stabiler
Messwert vorliegt. Ein Abbruch mit Übernahme des aktuellen Messwerts ist
jederzeit mit <RUN/ENTER> möglich.
Messbereichswahl
AutoRange
Es stehen für Leitfähigkeitsmessungen mehrere Messbereiche zur Verfü-
gung. AutoRange bewirkt, dass das Messgerät bei Überschreiten eines
Messbereichs automatisch in den nächsten Messbereich wechselt. Bei ein-
geschalteter Funktion AutoRange erscheint die Anzeige ARng.
Temperatur-
messung
Das Messgerät misst die Temperatur der Messlösung automatisch mit dem
integrierten Temperaturmessfühler der Leitfähigkeitsmesszelle (Anzeige
TP). Bei Messzellen ohne Temperaturmessfühler kann die Temperatur mit
<▲> <▼>manuell eingegeben werden.
Faktor für
Filtrattrocken-
rückstand
Der Faktor zur Bestimmung des Filtrattrockenrückstands ist im Bereich 0,40
bis 1,00 frei einstellbar. Er wird im Messmodus TDS zusätzlich zum Mess-
wert angezeigt. Faktor gegebenfalls mit <▲> <▼>ändern.
Temperatur-
kompensation
Sie können unter folgenden Einstellungen wählen:
!Nichtlineare Temperaturkompensation (nLF) nach EN 27 888
!Lineare Temperaturkompensation (Lin) mit einstellbarem Koeffizienten
von 0,001 ... 3,000 %/K
!Keine Temperaturkompensation (- - - -)
Zum Einstellen der Temperaturkompensation <CAL> drücken, bis tc er-
scheint. Anschließend mit <RUN/ENTER> bestätigen. Mit <CAL> ge-
wünschte Option wählen. Gegebenenfalls Temperaturkoeffizienten mit
<▲> <▼>einstellen. Mit <M> zurück zum Messmodus.
