Frequently Asked Questions - GP100-USB Brecknell
How do I calibrate the GP100-USB scale?
To calibrate, first ensure the scale is on a stable surface and turned on. Press and hold the CAL key until 'CAL' appears. Then place a 100 g standard weight on the platform. The scale will automatically calibrate and return to weighing mode. Use only certified calibration weights.
How do I connect the scale to my computer via USB?
Connect the USB cable from the scale to your PC. The scale may require drivers; download them from the Brecknell website if not auto-detected. Once connected, the scale acts as a virtual serial port. You can use data collection software like Brecknell’s SPC or any terminal program.
What software can I use with the GP100-USB?
Brecknell provides SPC (Scale PC Connect) software for data logging and analysis. It is compatible with Windows. Alternatively, you can use any program that reads serial data, such as HyperTerminal or custom scripts.
How do I change the weighing units?
Press the UNIT button repeatedly to cycle through available units: g, oz, ct, dwt, ozt, lb, tael, grain. The display will show the current unit.
How do I use the tare function?
Place a container or empty item on the platform and press TARE. The display will zero. Then add the material to weigh only its net weight. The tare value remains until removed or cleared.
What does an 'Err' message mean?
An Err message indicates overload (weight exceeded capacity) or an unstable reading. Remove the weight and ensure the scale is on a level, vibration-free surface. If error persists, try recalibrating.
How do I clean and maintain the scale?
Clean the platform and casing with a damp, soft cloth. Do not use solvents, abrasive cleaners, or immerse in water. Keep the scale in a dry environment to prevent damage.
What power options are available?
The scale can be powered by the included AC adapter (input: 100-240V) or by 6 x AA batteries (not included). For consistent performance, use the AC adapter. Batteries are recommended for portable use.
How do I set the auto-off timer?
Press and hold the MODE key until 'A-OFF' appears. Use the arrow keys to select the desired timeout (1, 2, 5, 10, 30 min, or OFF). Press MODE to confirm. The scale will turn off automatically after inactivity.
What is the warranty period and how do I claim it?
The Brecknell GP100-USB comes with a 1-year limited warranty. For claims, contact Brecknell customer support with your proof of purchase and a description of the issue. Do not disassemble the scale; it voids the warranty.
