- Secure all connections to maintain the enclosure's integrity.
Initial Power On
Press the ON/OFF button to power on the indicator. The display will perform a self-test and then show the current weight reading.
5. Operating Instructions
The TI-500 SL features a user-friendly front panel with dedicated function keys.
Basic Weighing
Once powered on, the indicator will display the weight detected by the connected load cells. Ensure the scale platform is clear before taking a measurement.
Zeroing the Display
To set the display to zero when there is no load on the platform:
- Press the ZERO OFF button. The display will reset to 0.00.
Taring (Net/Gross Weight)
To measure the net weight of an item by subtracting the weight of a container:
- Place the empty container on the scale platform.
- Press the TARE button. The display will show 0.00 and the 'NET' indicator will illuminate.
- Add the item to be weighed into the container. The display will now show the net weight of the item.
- To return to gross weight, press the NET GROSS button.
Unit Conversion
To switch between available weighing units (e.g., kg, lb):
- Press the UNITS button. The display will cycle through the configured units.
Printing Weight Data
If connected to a compatible printer via the RS-232 port:
- Press the ON PRINT button to send the current weight reading to the connected device.
Calibration
Calibration procedures are typically performed by qualified technicians. Refer to the detailed technical manual or contact Transcell Technology support for calibration instructions. All setup parameters can be entered via the front panel keys during calibration mode.
6. Maintenance
Cleaning
