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.
NIST traceable calibration certificate. Must be purchased at the same time as the L261 data logger.
Please Note: This calibration certificate requires a 2 week lead time (adds two weeks to shipping times) and cannot be returned for a refund.

*This unique recording mode provides the opportunity to continuously record over long periods of time by reducing the storage resolution of the stored data and maintaining matching resolution for the newest data. Each time the memory fills up using XRM™, every other of the oldest stored samples is discarded making room for newer samples. This process continues until the recording is manually stopped.
**A memory backup capacitor provides backup power while the batteries are being changed. This backup capacitor will maintain the instrument for up to 10 seconds without batteries installed. After 10 seconds the date and time will need to be reset (data and configuration will be maintained). If the unit is connected to DataView® via a PC, the battery life is 100 hours regardless of the storage rate.
*** Input level beyond this range may damage the instrument.
