CO-1: External Calibration

Step 1 : After switching to CO-1, (timing area: CO-1, the scale area display default is the specification maximum) (the system has a memory function, what value was selected last time will be displayed by default, the initial operation default is the maximum weighing value), click the on/off key to cycle switch 5000.0/3000.0/2000.0/1000.0/500.0/200.0 /100.0/50.0/20.0/10.0/6.0

Step 2: After selecting the value (the first value of the entry menu does not blink without operation, not until the cycle is done),no operation for about 5 seconds, after displaying CAL, the value flashes.

Step 3 : Then put the corresponding weight on the scale surface.

Step 4 : Blinking about 3 times after the display PASS, and then the value does not blink, (to enter the weighing interface, if you have set other menus before then it is considered saved)

Press and hold the off key in the middle to shut down and exit directly, the program is not saved

CO-2 : Clock Head Connection.(This function requires a package clock header, if no clock header can be ignored this function)

Step 1: After switching to CO-2, (timing area: CO-2, the default for the weighing area is the value 0) (0 represents not connected) (the system has a memory function, what was selected last time is displayed by default, the default for initial operation is 1), click on the on/off key to cycle switch 1/2/3/4/5/6/7/8/9/0 (There are 10 frequencies in total, as soon as you enter this program, the symbol of the display link is the flashing status, 0 represents not connected)

Step 2 : Electronic scales and clock head are selected to adjust the same frequency, if successful, the  symbol linked to the clock head is always on, if the connection is unsuccessful, the linked symbol keeps flashing, (if you do not set other parameters, the save and exit operation is to long press the timer key) and then set other parameters operation: click the timer key to cycle through the next
menu CO-1/CO-2/CO-3/CO-4/CO-5/CO-6/CO-7/CO-8/CO-9/CO-10

This function is set as long as the connection is successful, regardless of whether it is saved or not, all considered as connected and saved.

This function requires a package clock header, if no clock header can be ignored this function.
