Alarm Signs
| Sign | Alarm Cause | Solution |
| Err1 | RAM Failure. | Replace the chip RAM. |
| Err2.1 Err2.2 | EEPROM Failure. | Replace the chip EEPROM. |
| Err3 | Unused. | |
| Err4 | ADC Failure. | Replace the ADC module. |
| oV-Ad | Over ADC Range. | Weighing signal exceeds A/D conversion range. 1. Check if the loadcell is connected. 2. Check if the capacity of loadcell is too small. 3. Check if the loading weight is too big. |
| oL | Overload Alarm. | Gross Weight > (Scale Capacity + 9 × Scale Division). 1. Check if the loadcell is connected. 2. Check if the capacity of loadcell is too small. 3. Check if the loading weight is too big. |
| oV-nZ | Over ‘Manual/Auto Zero Limit’. | Refer to parameter [123] ‘Manual/Auto Zero Limit’. |
| tXX.XX | Preheating Time Countdown [min.sec]. | Refer to parameter [128] ‘Zero Upon Power Up’, [129] ‘Power Up Zero Time’ and [130] ‘Power Up Zero Limit’. Wait for the preheating time over or press any key to exit. |
| oV-Zr | Over ‘Power Up Zero Limit’. |
