RUSTRAK RANGER RR2-1258-3 Harmonic Power Logger System

The RUSTRAK Ranger RR2-1258-3 Harmonic Power Logger System is a 1250 Series Harmonic Power Logger built to live in a meter housing and capture harmonics and power‑quality data in a single session. It provides 3 voltage inputs built into the meter blades, 2 current channels, and 4 math channels for derived measurements, enabling simultaneous logging of L1–N, L2–N, and L1–L2 configurations. Model 1258 is designed for use with current probes that have 1 A or 5 A outputs, offering flexibility across different metering setups. Recording length ranges from 10 seconds to 999 days, and the unit operates from -10 °C to 60 °C with 128 K of internal memory for storing captured data. It delivers true RMS measurements up to the 50th harmonic and includes Harmonic Scan to sweep all harmonics on any voltage or current input channel. Data is retrieved via an RS-232 port and the system can be configured from a computer or an optional keypad, with a backlit graphic touchscreen display and compatibility with Pronto for Windows software. This Ranger data logger family is designed to address voltage complaints and power‑consumption issues by capturing harmonics, THD, and other AC parameters in a compact, field‑deployable package.
