VII. CALIBRATION
A. Calibration using a Load-Cell Simulator.
REQUIRED TOOLS / ITEMS:
-Screwdriver: Medium, flat blade. (To Open/Close the TCX indicator.)
-A load-cell simulator which can achieve 0mV/V and .4mV/V settings.
1.) Turn on the indicator
2.) Open the indicator and press the tiny black push-button “SW1” one time.
(Refer to page 25)
3.) Press [YES/ENTER] one time, the indicator will display “ConFig”
4.) Press [ESC] three times, the indicator will display “CAPCty”
5.) Press [YES/ENTER] one time, then use the [NO/CLEAR] key and the
NUMBERS on the keypad to enter a desired Capacity.
(The TCX-1300 User Defined Capacity “CAPCty” can be set to equal the
maximum amount of weight which may be loaded onto the scale system, plus
the amount of weight already on the load-cells.)
For commercial applications the “CAPCty” is limited to 10,000 graduations.
To calculate the capacity (in this case,) multilply 10,000 times your
graduation size. Example: 10,000 * 5 = 50,000
Once the desired Capacity is visible on the indicator, press the [YES/ENTER]
keypad. The indicator will display “CAL 0”
6.) (Make sure a load-cell simulator is connected to the indicator and set to 0.0
mV/V,) With “CAL 0” still being displayed, make sure the motion LED is not
lit, and press the [ZERO] keypad for approximately one second. The
indicator should display “CALPnt” at this time.
7.) Switch the load-cell simulator to .4 mV/V.
8.) With “CALPnt” still being displayed on the indicator, press [YES/ENTER].
