3-1. How to Connect Load Cell
Connect the load cell connector to the load cell port on the back of the indicator.
* How to connect the load cell to the connector.
Pin
Number Pin Function
1 EXC+
6 SEN+
2 EXC-
7 SEN-
3 SIG+
4 SIG-
5 SHIELD
Note 1. When 4 line load cell is used, connect EXC+ and SEN+ to '+' power supply terminal
in the load cell input, and connect EXC- and SEN- to '-' power supply terminal in the
load cell input.
* Relationship between the load cell output and input sensitivity.
The input sensitivity of this product is maximum 0.2uV/digit or more.
The following equation should be satisfied upon the system design.
Applied voltage of load cell x Output voltage of load cell x Value of a
division
0.2uV ≤------------------------------------------------------------------------------------------------
Rated capacity of load cell x Number of load cell
Example 1) Number of load cell: 4 ea
Ratedcapacityofloadcell:500Kg
Ratedoutputofloadcell:2mV/V
Valueofadivision:0.10Kg
Applied voltage of load cell: 10V (= 10,000 mV)
According to the equation(10000 mV* 2mV * 0.1Kg)/(500Kg * 4) = 1 ≥0.2uV
As the calculated value is greater than 0.2uV, this weight system design has no problem.

It refers to the calibration to set the displayed value to the actual weight in displaying weights.
How to Access to the Weight Setup Mode
Turn on the power supply to access to the weight setup mode while pressing Cal S/W after
removing the sealing. Press the setup key long in the weight setup mode to return to the
weighing mode.

Note 1. The minimum division means the value of a division.
Note 2. Set the external resolution within 1/30,000 as the value by dividing the maximum weight by the minimum
division.
If the external resolution is 1/30,000 or more, Err 21 is shown.
Note 3. The position of a decimal point is decided by the position of a decimal point for the minimum division set
in CAL2.
Note 4. If the minimum division is set to any value out of 1, 2 and 5 unit, "ERR DIV" is shown.
