Description

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.

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
Recording modes Instantaneous recording: at every recording interval
Statistical value recording: Measure at one second intervals, and record the instantaneous, maximum, minimum, and average values within every recording interval
Recording methods One-time recording: Stop recording when the memory capacity is full
Endless recording: Continue recording even when the memory capacity is full (old data is overwritten)
Start: Logger button operation or scheduled time
Stop: Logger button operation or scheduled time, or auto-stop when the memory capacity is full (at one-time recording)
Other functions Always backs up last recorded data; backs up recorded data and setting conditions when battery power is low; guarantees approx. 30 sec. of recording operation and clock while battery is replaced
Waterproof and dust-proof N/A
Interfaces Infrared optical communications with LR5091, LR5092-20
Power supply LR6 (AA) Alkaline battery ×2, Battery life: Approx. 1 year (Instantaneous recording, with 1-minute interval and auto power saving, at 20 °C), Approx. 1 month (Instantaneous recording, with 1-second interval at 20 °C)
Dimensions and mass 79 mm (3.11 in) W × 70 mm (2.76 in) H × 37 mm (1.46 in) D, 165 g (5.8 oz)
Accessories LR6 (AA) Alkaline battery (built-in internal) × 2, Instruction manual × 1, Operation guide × 1

Key Features
