Precise and Dependable Load Cell Simulator

The Ranger 7 is the simulator of choice for precision testing. Designed for applications that require high resolutions, it features a switchable offset and two Vernier controls, along with switches that go down to 0.01 mV/V.
Ideal for testing and diagnostics of digital weight indicators, calibration of A/D converters, and calibration with load cell datasheets. Suitable for simulating 1 and 4 load cell systems.

Technical Specifications

Vernier:
Two ranges; one is equal to the sum of the 0.05 mV/V switch and the 0 to 0.5 mV/V switch. The other is the sum of the 0.5 mV/V, 0.1 mV/V and 0.01 mV/V switches.

Load Impedance:
Three settings:
X0.5: 700 ohm
X1: 350 ohm (one standard load cell)
X4: 87.5 ohm (four load cell platform)

Linearity:
± 0.01% + 1µV

Connectors:
Low Thermal Electronics, Type 2758 precision gold plated binding posts, standard banana jacks or
14 AWG wire

Temperature Coefficient:
5 ppm/ °C

Zero Offset:
± 0.0005 mV/V

Output Range:
0 to 3 mV/V in 0.01 mV/V steps

LED Annunciators:
EXC +
EXC –
Offset ON
0.5 mV/V
0.1 mV/V

Calibration without Weights

Theoretical calibration of weighing systems without the use of sample masses! Useful in high-capacity weighing systems such as silos and hoppers.

Load cell simulation: The load cells supplied with calibration certificate show the actual value of the output signal at full load. RANGER 7 is able to replicate the cell signal and use it to perform theoretical calibration of the weighing system.

A/D converter calibration: Adjust the A/D converter and enter the mV/V value of the fully loaded cell signal indicated on the calibration certificate on the weight indicator.

This load cell simulator is manufactured with high-precision electronic components and has a signal simulation sensitivity of 0.01mV/V. It is also capable of simulating the impedance of 1 and 4 load cell systems.
