Not many computers these days come with a COM port. USB has replaced the serial COM port on most computers. The USB solution on our PC-150 uses a special driver on your PC to pro- duce what’s called a Virtual COM Port or VCP. This allows many legacy applications to work seamlessly with our scale because to them, it’s just another COM port.
ERROR CODES CODE MODE MEANING / POSSIBLE SOLUTION Normal Operating Mode A weight greater than 102% of the scale’s capacity has been applied to the scale. Remove the weight from the platter. Try re-calibrating the scale if this doesn’t solve the problem. Otherwise, possible load cell damage due to overloading.
