L452 – data logger for current, voltage, pulses and digital signals
Data logger with two independent inputs for DC signals, such as 4-20 mA and 0-10 V, as well as pulses and digital inputs. The sampling rate is adjustable from 200 ms to 1 h, providing 270 days of logging with 1 min sampling (200 ms with up to 36 days of logging). Alarms can be set and presented with any magnitude. The setting of scaling with magnitudes of measured values can be done independently of the channels.
The L452 Datalogger can compare the delay between two pulses on the two pulse inputs using a trigger pulse from a signal source (max 3.3 V, 1 MΩ impedance). Practical screw connection for easy and quick connection to the inputs. The Logger L452 has magnets on the back for easy attachment to the measurement site.
Up to 6 L452s can be connected and synchronized to the software to get up to 12 channels with the same time stamp. Recorded measurement values and measurement configurations are transferred via Bluetooth or USB with Swedish software. All keys on the front panel can also be locked. The instrument comes with rechargeable batteries for up to 270 days of measurements and a power cable with 5 V USB connection for longer measurements.
Included in delivery
The L452 data logger is delivered with software, screw terminal, manual, batteries, micro-USB cable and charger.

Nedladdning och installation:
1. Om du har en tidigare version av DataView installerad på din dator, se till att avinstallera den. STARTA OM PC:n
2. Den nedladdade filen är en .zip-fil. Packa upp den nedladdade filen på en plats i datorn som du kommer ihåg
3. Om du har ditt instrument uppkopplat mot PC:n, se till att koppla loss den från PC:n
4. Gå in i den mapp som har skapats i steg 3
5. Installera DataView genom att “högerklicka” på Setup.exe-filen och välj “kör som administratör”
6. Välj “Svenska” som språk i början av installationen
7. Följ instruktionerna…
W10/11 tips:
Det kan krävas att installationen måste utföras genom att högerklicka med musen på startikonen och ”Kör som ADMIN”.
Vid slutet av installationen måste du eventuellt svara OK på några frågor.
En svart DOS-ruta visas en kort stund då drivrutinerna installeras.
PC med W10 ska startas om innan du kan använda mjukvaran.
