Produktnummer: L261

Model L261 is a member of the Simple logger II series of instruments and is designed for stand-alone high voltage DC and TRMS AC measurements. It features a pair of safety banana sockets that accepts a direct connected voltage of up to 600 V with 0.1-volt resolution using the provided test leads and clips without any external signal conditioning. The instrument features a built in 240,000-sample memory, integrated LED indicators to display status, and a built-in USB interface for uploading configurations and downloading recorded data.

The L261 is powered from two standard AA cells providing complete portability, and a "use anywhere" design. The L261's data logging function supports sample intervals ranging from once every 125 milliseconds (eight times per second) to as long as once every day. Each L261 measurement is synchronized with the AC line such that 64 samples over one AC line cycle are taken. Frequency tracking is performed over the range of ±2Hz around the nominal line frequency (50 or 60Hz). An integrated real time clock provides time and date stamping of logged voltage data.
