5.0 Functions
5.1 Totalization
F 1.10=0
Operation: Normally add weights to scale and press 〖TOTAL〗. The screen shows “Add-” and returns to the main weighing interface. Remember to zero the scale before putting things on scale every time; otherwise, there is no totalization.
Check and clear: Normally long press 〖TOTAL〗and “TOTAL ” shows for one second.
Then the total quantity interface “Cn xxx” and the total weight interface “t xx.xx” show.
Press〖Print〗or 〖GROSS〗 to switch between the above two interfaces. Press 〖ZERO〗 to clear the total quantity or the total weight value. Press 〖ON/OFF〗to confirm and press 〖COUNT〗to exit.
5.2 Counting
F 1.10=1
Operation: Normally press 〖COUNT〗to switch between the weight and quantity display.
Sampling: Long press 〖COUNT〗 until “SAMPLE” shows. Press 〖ON/OFF〗 and as “Sn XXX” shows, put in the correct quantity. If F 2.4=0, put the corresponding quantity on scale and press 〖ON/OFF〗to confirm the sample quantity and weight; if F 2.4=1, press 〖ON/OFF〗 and as “XXXXXX” shows, put in the corresponding weight and press 〖ON/OFF〗 to confirm the sample quantity and weight.
Appendix Ⅰ Indicator Prompt Message
Normally the indicator is stable and reliable. If the indicator fails, restart it first. Find out what the error is before repairing it. Repair the indicator according to the error codes.
| No. | Code | Error | Countermeasure |

|
| 2 |  |
load above upper limit | Reduce load |
| 3 |  |
load less than lower limit | Press『Zero』to reset |
| 4 |   |
Out of zeroing range | Remove load on scale if any. |
| 5 |  |
Invalid | |
| 6 |  |
EEPROM verification and error | Press 〖ON/OFF〗to restore and then restart. If the code shows again, return the indicator to factory; if there’s no code re-calibrate the indicator. Note: Restoring factory default includes restoring all parameters. |
| 7 |  |
The scale is dynamic during calibration | Check the scale |
| 8 |  |
Wrong date or time | Set date and time as required |
| 9 |  |
Wrong AD initialization | Restart. If the error shows again return the indicator to factory. |
| 10 | |
load calibration: load weight to scale | Add weights to scale as required |
| 11 | |
Enter into menu setting | Press 〖ON/OFF〗to continue setting. |
