CHAPTER 6: CALIBRATION
6.1 CALIBRATION OVERVIEW
Your TC-2005 scale ships from the factory fully calibrated. There is no need to calibrate the
scale unless you feel that it has become inaccurate. It is a good idea to check the
calibration of your scale from time to time with a precision test weight. Transcell
recommends that you perform a new calibration on your digital scale at least once a year.
During calibration, at least two values are saved in the scale’s memory – the zero
value (deadweight) and the up to three span values (test weights). See Table 6-1
for a listing of minimum and recommend test weights.
If you plan to use a remote scale, you must calibrate it before use. The remote
scale calibration allows only one span value (test weight). The recommended
test weight is 67% of full scale and the minimum test weight is 1% of full scale.
6.2 CALIBRATION MODE – TC-2005 SCALE
1. Press the SETUP/CAL key at any time. The scale prompts for a password (“000000”).
2. Key-in the password (336699) and press ENT. The scale displays “CAL-L”.
3. Press the TARE key. The scale shows ”C 0” followed by a value. The value shown is
for troubleshooting purposes only. Allow a 20-minute warm-up period for the load cell
and electronic components to become thermally stable.
4. Remove all items from the scale’s platter. Press ZERO to zero the value.
5. Press the SAMPLE key to save the zero point value. The scale briefly shows “SAVE”,
followed by “SET” and “ENDC0”. The scale then shows “C 1” followed by "0.000". The
“C 1” indicates that the scale is prompting for the first span calibration value.
6. Use the four directional keys (shown in Figure 6-1 below) to adjust the displayed value
to the actual test weight value. Increase the flashing digit by pressing the ZERO key.
Decrease the flashing digit by pressing the TARE key. Pressing the PRINT key or the
UNIT key will change the position of the flashing digit.
7. Place the test weight(s) onto the scale’s platter, then press the SAMPLE key. The scale
briefly shows “SAVE”, followed by “SET” and “ENDC1”. If the calibration was
successful, the display will prompt for the next span calibration value.
8. If you wish to use up to two more calibration test weights, repeat Step 7 twice. Each
subsequent test weight must be greater than the last. If you do not wish to use more
calibration test weights, simply press SAMPLE twice.
9. Press the ZERO key once to exit calibration mode and enter Normal Operating Mode.
Remove the test weight from the platter
NOTE: If you encounter a failure, consult Appendix C for possible causes and
remedies.
