F701-P Global standard model basic performance design weighing indicator
Category: weighing indicator
Specifications
Details
F701-P is a weighing indicator with convenient functions and operability for weighing such as a high-precision amplifier, fast-sampling, High-Low limit comparison function, weighing function and accumulation functions.
"Load cell" is a sensor that measures a weight or a force.
For the load cells as well as amplifiers and indicators where the load cells are connected to, there are "4-wire type" and "6-wire type". If not wired properly, it may cause not only inaccurate measurements, but also may be affected by the temperature or the cable length.
This time, we will explain the wiring method of both 4-wire type and 6-wire type.
