The Rice Lake Ranger 7 Variable Range Simulator is a professional-grade, high-resolution load cell simulator designed for advanced calibration, troubleshooting, and testing of electronic weighing systems. Built for service technicians, calibration laboratories, and industrial weighing professionals, the Ranger 7 provides highly accurate simulated load cell signals for verifying and calibrating digital weight indicators without requiring an actual scale platform.
Engineered for applications requiring exceptional resolution, the Ranger 7 features output adjustments down to 0.01 mV/V increments, allowing precise calibration of high-performance indicators and A/D converters. Its dual Vernier control design enables fine signal adjustment and repeatable test results for demanding calibration procedures.
The simulator includes a switchable offset function and multiple precision control ranges, making it ideal for testing indicator response, validating calibration parameters, and comparing performance against load cell datasheets. It is particularly useful for diagnosing indicator problems, verifying scale electronics, and performing advanced system troubleshooting.
Three selectable impedance settings allow the Ranger 7 to accurately simulate various weighing system configurations:
- X0.5 = 700 Ohms
- X1 = 350 Ohms (one standard load cell)
- X4 = 87.5 Ohms (four-load-cell platform)
This flexibility makes it suitable for testing both single-load-cell and multi-load-cell weighing systems.
The rugged painted die-cast enclosure provides excellent durability for field service and laboratory environments. Precision gold-plated binding posts accept standard banana plugs or up to 14 AWG wire, ensuring secure and reliable connections during testing.
Whether you're calibrating truck scale indicators, floor scales, tank weighing systems, process control equipment, or industrial weighing instruments, the Ranger 7 delivers the accuracy and reliability required for professional calibration work.
