○ZERO: Light on when present weight is within 0±1/4d. ○STAB: Light on when changes of weight values are within the range of motion detecting during motion detecting time. ○DATA: Light on when indicator displays the value of D/A output. Main Display: 6 digits, for displaying weight, value of D/A output, and the information of parameters. -

Page 11: 4-Wired Connection
2.3.2 4-wired Connection 1. The signals from the load cells are low voltage analog signals, which are easily affected by electro-noise, so the cables connecting load cells to indicator should use shielded cables, and not bind with other cables, especially power supply cables. 2. -

3 Calibration 3.1 Instruction (1) Calibration procedure must be executed when a Tuxon-A indicator is put in use at the first time, the preset parameters may no longer meet the user’s needs, and any part of the weighing system was changed. Position of decimal point, minimum division, maximum capacity, zero, and gain can be set and confirmed through calibration. -

3.3 Millivolt Value Display This function is mainly used for system test, position-error test for weighing mechanism and linearity test for load cell. 1. System Test (1) If display data changes with loaded weight changes, it shows that connection of load cell is correct and weighing mechanism works well. -
Page 16: Calibration With Weights
When it is not convenient to load a weight to calibrate, calibration can be done without weights using recorded data in the table in section 3.4. However, this method is just used for some emergencies, it will make calibration result incorrect if load cells, or indicator has been replaced. 3.5.1 Calibration without Weights for Tuxon-A... - Page 17 3.6 Explanation for Calibration Parameters Symbol Parameter Value of parameter Default Decimal Point 0/ 0.0/ 0.00/ 0.000 /0.0000 Min.
