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 applicaons, 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.
