Advantages

• DC voltage logger
• Detection of intermittent voltage faults
• Own power supply

Description

The Simple Logger II models automatically adapt their sensitivity (measurement range) and their acquisition rate to optimize recording. It is possible to program alarms or triggers on thresholds or on a predefined range. The LEDs on the front panel enable users to check the status of the logger and the remaining storage capacity at a glance. Compact and battery-powered, the Simple Logger II L481 is easy to position, even in an electrical cabinet.
