and it decreases to
. Finally,
appears for one second and zero calibration ends.

add weights
Add weights to scale and make sure: full capacity *50% ≤ weights ≤ full capacity. Press 『ON/OFF』. Enter the same value as the weights. Wait until the scale is stable and press 『ON/OFF』. The indicator shows
and it decreases to
.
Finally, appears for one second and load calibration ends.

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
