Advantages

• 2-channel current logger
• Own power supply

Description

For network monitoring,the ML912 logger acquires 64 samples per period. Frequency monitoring is performed on a range of ±2 Hz around the network's rated frequency (50 ou 60 Hz). The harmonic measurements are calculated from these 64 samples (available in the DataView® software). This Simple Logger® II model stores the TRMS values up to 8 times per second depending on the storage interval programmed by the user. The TRMS calculations are performed on a single period.
