Frequently Asked Questions - PB-300 CAS
How do I calibrate the CAS PB-300 scale?
To calibrate, press and hold the CAL button until the display shows a calibration weight value. Place the specified calibration weight on the platform, and the scale will automatically adjust. Refer to the manual for exact weight.
Why does my scale display 'Err' or 'Overload'?
This indicates the weight exceeds the maximum capacity of 300 g. Remove the excess weight immediately to avoid damaging the sensor. The scale will reset once the overload is removed.
Can I use the scale without batteries?
Yes, the scale can be powered via the included AC adapter. Plug it into the DC jack on the back of the scale. Batteries are only needed for portable use.
How do I change the unit of measurement?
Press the UNIT button repeatedly to cycle through available units (g, oz, ct, etc.). The selected unit will appear on the display.
What should I do if the display is faint or blank?
First, check the batteries or AC connection. If using batteries, replace them with fresh ones. If using AC, ensure the adapter is plugged in securely. A faint display often indicates low power.
Is the scale waterproof?
No, the scale is not waterproof. Avoid spilling liquids on the platform or housing. Clean with a slightly damp cloth and dry immediately.
How do I use the tare function?
Place an empty container on the platform and press the TARE button. The display will reset to zero. Then add your item to the container to see its net weight.
What is the recommended calibration weight?
The typical calibration weight is 200 g or 300 g. Check the manual for the exact value. Using an incorrect weight may result in inaccurate calibration.
Can I weigh items above 300 g?
No, exceeding the capacity may damage the scale. For heavier items, consider a scale with higher capacity.
How do I clean the scale?
Disconnect the power and remove batteries. Wipe the platform and casing with a soft, damp cloth. Do not use abrasive cleaners or immerse in water. Dry thoroughly before reuse.
