Frequently Asked Questions (FAQ)

• Can I use the HX760 with an Arduino or Raspberry Pi?
  Yes, but you will need an intermediate component. Since the HX760 outputs 0-10V or 4-20mA, you need an ADC module that can read these industrial levels (like an ADS1115 with a voltage divider or a specific 4-20mA to I2C converter) before connecting to a 5V/3.3V microcontroller.
• What is the difference between the HX760 and the HX711?
  The HX711 outputs a digital data stream (SPI/I2C-like) meant for microcontrollers. The HX760 is an industrial amplifier that outputs an analog signal (4-20mA or 0-10V) meant for PLCs and industrial DAQ systems.
• Why would I choose a 4-20mA output over a 0-10V output?
  A 4-20mA current loop is highly immune to electromagnetic interference (EMI) and can transmit signals over very long distances without voltage drop, making it the standard for noisy industrial environments.
• How do I calibrate the zero point on the HX760?
  Remove all weight from the load cell. Use a multimeter to measure the output signal. Turn the "Zero" potentiometer on the board with a small screwdriver until the output reads exactly 4.00mA (or 0.00V, depending on your selected output).
• How do I calibrate the span (max weight) on the HX760?
  After setting the zero point, place a known, accurate weight on the load cell (preferably near its max capacity). Turn the "Span" potentiometer until the output reads the expected proportional current or voltage (e.g., 20.00mA for max capacity).
• What power supply voltage does the HX760 require?
  It requires an industrial standard DC power supply, typically between 12V and 24V.
• Can it power the load cell directly?
  Yes, the module has built-in excitation circuitry (E+ and E- terminals) to power the attached strain gauge load cell.
• Does the HX760 support 4-wire or 6-wire load cells?
  It directly supports standard 4-wire load cells. If using a 6-wire load cell, tie the Sense+ to Excitation+ and Sense- to Excitation- at the amplifier terminals.
