limiting).
Almost all measuring cells fulfill these conditions.

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 instrument 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 T
Warning
Only use original plug-in power supplies (see T

The AutoRead function checks the stability of the measurement signal (except 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 measured value is reached. This can be terminated at any time taking over the
current measured value with <RUN/ENTER>.
There are several measuring ranges available for conductivity measurements. 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.
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 temperature can be entered manually with <▲> <▼>.
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 <▲> <▼>.
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 %
! 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.
Calibration
evaluation
You can determine the cell constants of the conductivity measuring cells in
the range of 0.450 ... 0.500 cm
You can also set the cell constants manually in the ranges
! 0.090 ... 0.110 cm
! 0.250 ... 2.500 cm-1
or select the fixed cell constants 0.010 cm
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:
! 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.

automatically Int 1
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 instrument changes to the measuring mode.
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 chronological 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 pressing the <RCL> key, you reach the following functions:
StO dISP Output stored data on the display
StO SEr Output stored data via the serial interface
Transmitting data
manually
Transmitting data
automatically Int 2
CAL dISP Output calibration data on the display
CAL SEr Output calibration data via the serial interface
Start the output with <RUN/ENTER>.
Transmitting data
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.
The interval to the data transmission (Int 2) determines the chronological interval between automatic data transmissions. After the selected interval expires, 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 <▲> <▼>.
