The HT Italia XL421 can perform measurements and recording of True-Rms AC current up to 2500 amps in a single phase system. Applications include evaluation of load consumption, verification of nominal power of transformer, etc. The instrument is contained in a safety IP65 case with built-in flexible clamp which is easily connected to a variety of cable and bus-bar sizes. The system can record for a very long time, up to around a year. With DATALINK Windows software supplied with the model, the recorded data is easily downloaded to a PC for analysis.
