Build Quality, Materials, and Ergonomics
The physical construction of the RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser reflects RCBS’s commitment to longevity. The housing is crafted from a reinforced, anti-static polymer designed to resist the “clinging” effect often seen with powders like Hodgdon Varget or Alliant Reloder 15. This anti-static property is critical for maintaining accuracy, as stray grains or static charges can interfere with the load cell’s sensitivity.
Ergonomics and Interface
The RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser features a large, backlit LCD touchscreen that is angled for easy viewing whether the operator is sitting or standing. The tactile feedback of the screen is responsive even when wearing gloves. One of the standout ergonomic features of the RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser is the external battery pack compatibility (sold separately), allowing for field use where AC power may be unavailable. The “mechanical advantage” here isn’t found in a lever, but in the streamlined workflow of the touch interface, which allows for rapid changes between grains and grams, or for setting custom “Auto-Dispense” parameters that trigger the next drop as soon as the empty pan is returned to the platen.
Comprehensive Setup, Calibration, and Operation
To achieve the best results with the RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser, the setup environment must be carefully managed. The unit should be placed on a heavy, vibration-free bench away from HVAC vents or fluorescent lighting that can cause electronic “drift.”
Step-by-Step Assembly
- Leveling: Use the built-in bubble level and adjustable feet to ensure the RCBS ChargeMaster Supreme Digital Powder Scale and Dispenser is perfectly flat.
