4.2.2 Standard Load Cell Connection
The load cell wiring should be made carefully before energizing to avoid damages to the weight indicator and
the load cells. The input resistance of the load cells that you want to connect should be more than 58 Ω.
The sense pins of the instrument should be connected. In 4-wire installations the sense and excitation pins with
the same polarity should be short circuited at the connector side.

4.3 Commissioning
After making the required installations and connections to your indicator, turn the power on and perform
following steps:
 Get familiar with the instrument’s setup mode (see chapter 6.1)
 Set up the application mode (see chapter 6.2)*
 Define the configuration parameters (see chapter 6.3)*
 Define the scale parameters (see chapter 6.4)
 Calibrate the scale (see chapter 6.5)
* Note:
Most of the parameters can be skipped for later setup. Please take care for the parameters which may
be locked by the J2 calibration jumper in legal for trade applications (see Appendix 1: Setup and Calibration
Menu of the instrument).
If you want to use the Flintec IndFace Software for FT-12 then you have to set up the instrument’s standard
serial interface to host mode (see chapter 9.2) before you adjust all the configuration parameters.
After checking the performance of your weighing instrument you can begin to use the indicator.
If there are peripheral connections, first you should turn the power off; make the peripheral connections, perform
the required safety checks and energize the indicator. Then set the related parameters and check if the
peripheral devices are operating properly.
If required perform following additional steps:
 Set up the memory functions (see chapter 7)
 Set up the serial interfaces (see chapter 9.2)
 Printer setup (see chapter 9.2)
 Set up other optional inputs and outputs (see chapter 9.3 and 10)
