2. PRESENTATION OF THE INSTRUMENT
2.1. FUNCTIONS OF THE INSTRUMENT
The L452 Data Logger is a two-channel recorder. It can be powered either by the rechargeable batteries or by mains, via a USB cable.
It is used:
to record DC voltages up to 10V,
to record direct currents from 4 to 20mA,
to count pulses,
to detect events on its discrete inputs.
The voltage and current measurements can be sampled at intervals from 200ms to 1 minute. The sampled quantities can be av-
eraged (means) over periods from 200ms to 1 hour and recorded in the internal memory.
The L452 Data Logger is used to check and measure process applicaons, water, gas, and power meters, or to monitor
the environment. It can operate in the local mode or in the remote mode. It can communicate by USB or by Bluetooth.

3. SETTINGS OF THE INSTRUMENT
Before you use the L452 for the rst time, you must congure it. It can be congured either in the local mode (on the keys of the
instrument itself) or in the remote mode (using the Data Logger Transfer software).
The parameters to be congured are:
The language,
The date and time,
Activation or non-activation of the Bluetooth link,
Activation or non-activation of the visibility of the instrument on the Bluetooth network,
The name of the instrument for the Bluetooth link.
3.1. ORGANIZATION OF THE SCREENS
The screens are organized into 6 categories.
The measurement screens display the measured data (including the minimum and maximum values) of the two input channels.
They can be accessed directly by switching the instrument on.
The recording screens, used to start, stop, schedule, and congure recording sessions.
They can be accessed by pressing the key once.
The channel 1 conguration screens, used to activate the channel and dene the type of input, the measurement unit, the
transformation coefcient, and the alarm.
They can be accessed by pressing the key twice.
The channel 2 conguration screens, used to activate the channel and dene the type of input, the measurement unit, the
transformation coefcient, and the alarm.
They can be accessed by pressing the key three times.
The conguration screens of the instrument, used to dene the language, the date and time, and the Bluetooth link. They are
also used to clear the memory, to reset the conguration, and to reset the minimum and the maximum.
They can be accessed by pressing the key four times.
The instrument information screens, which are read-only and display the serial number, the internal software version, the name
of the instrument on the Bluetooth network, and the state of the memory.
They can be accessed by pressing the  key ve times.
3.2. CHOOSING A LANGUAGE
Switch the instrument on by pressing the On/Off key and keeping it pressed until the display unit indicates POWER ON.
