CLAMP LOGGER LR5051 Easily Record Load Current of 50Hz/60Hz Lines and Leak Current Overview Hioki compact 1 or 2-channel data loggers feature a 60,000 data set/channel memory to measure temperature, humidity, voltage or instrumentation signals. The LR5051 logs current over 2 channels in as fast as 1 second intervals. Key Features • - Easily mount the light-weight, pocket-sized loggers in tight spaces • - Easy-to-see dual display • - Transfer data to PC even during recording • - Replace batteries while recording (30 second limit) • - 3 times the memory capacity compared to predecessor (Record 60,000 data per channel) • - Record without missing fluctuations in STAT mode • - Measurement data is preserved even after the battery dies • - Worry-free backup preserves recorded data even if a new measurement is started by mistake Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year) Measurement items - AC Current 2 channels (used with the optional current sensor; load current 2ch, leak current 2ch, or load/leak each 1ch) Caution: Current and leak current that occur intermittently cannot be measured. Measurement range - 500.0 mA to 1000 A AC rms, 5 range (depends on current sensor in use) Basic accuracy - ±2.0% rdg. ±0.13% f.s. (main unit + current sensor accuracy, at 500.0 A range, 50/60 Hz) Note: Basic accuracy is typical value, only main unit accuracy: ±0.5 %rdg. ±5 dgt., must added clamp sensor accuracy, refer to the detailed catalog Storage capacity - Instantaneous value mode: 60,000 data/ch, Statistical value mode: 15,000 data/ch Recording interval - 1 to 30 sec., 1 to 60 min., 15 selections
