1. Calibration & Gravity Compensation
1.1. Calibration
To enter calibration mode:
When the power is off, press the [power-key] while pressing the [H-key]. When 'G-CAL' is displayed, and then press the [enter-key]. This initiates the calibration mode.
| No. | TITLE | DISPLAY | KEYBOARD & DESCRIPTION |
|---|---|---|---|
| 1 | How to enter | G-CAL | [power-key] + [H-key] + [enter-key] |
| 2 | Program version | T=100 | Move to the next step automatically |
| 3 | Maximum capacity | CAPA 5000 | Initialized value [H-key]: numeric increase [T-key]: scale increase / [enter-key]: save |
| 4 | Minimum division | d 2 | [H-key]: decrease / [T-key]: increase [enter-key]: save |
| 5 | Setting weight | SET-F 5000 | Initialized value [H-key]: numeric increase [T-key]: scale increase / [enter-key]: save |
| NB: Setting weight shall be within the range of 10%~100% of max. capacity | |||
| 6 | Zero calibration | ZERO | Unload the tray and press [enter-key] |
| 7 | Span calibration | LOAD ----- | Load the weight which was set in step 5 and press [enter-key] |
| 8 | Finish | END | Unload the tray and press [enter-key] |
1.2. Gravity compensation
To enter gravity compensation mode:
When the power is off, press the [power-key] while pressing the [H-key]. When 'G-CAL' is displayed, and then press the [H-key] again. This initiates the gravity compensation mode.
| No. | TITLE | DISPLAY | KEYBOARD & DESCRIPTION |
|---|---|---|---|
| 1 | How to enter | G-CAL | [power-key] + [H-key] + [H-key] |
| 2 | Program version | T-100 | Move to the next step automatically |
| 3 | Calibration location | GRAV1 9799 (9.799m/s²) | Initialized value [H-key]: numeric increase [T-key]: scale increase / [enter-key]: save |
| 4 | Using location. | GRAV2 9799 (9.799m/s²) | Initialized value [H-key]: numeric increase [T-key]: scale increase / [enter-key]: save |
| 5 | Finish | END | Unload the tray and press [enter-key] |
Note: If the GRAV1 value is the same as GRAV2, compensation is not required.
1.3. Check message
| Code | Description |
|---|---|
| CH 03 | The resolution is set to be exceeded the limit 1/50,000. Check the resolution. |
| CH 04 | The balance weight for span calibration is lower than 10%, or greater than 100% of the maximum capacity of the scale. The weight for span calibration should be within 10%~100% of the maximum capacity of the scale. |
| CH 05 | Load cell output is too small or large at span calibration. Check the weight unit and load cell or calibrate with lower resolution. |
2. Wireless Pairing
How to enter the pairing mode:
- TCB crane scale: When the display is off, press the [power-key] while pressing the [H-key]. When "T=401" (Firmware version) is displayed, press the [H-key]. Then, "RFSET" is displayed.
- TD3000(2300)F wireless display: Press the [power-key] to power on and immediately press the [H-key]. And press the [H-key] again. Then, "RFSET" is displayed.
- TF-100 controller: When the display is off, press the [power-key] while pressing the [HOLD-key]. When "T=601" (Firmware version) is displayed, press the [3-key]. Then, "RFSET" is displayed.
- TF-400 controller: Press the [star-key] and [H-key] at the same time. And then, press the [H-key]. Then, "RFSET" is displayed.
- TF -200 wireless dongle: Press the [SET] KEY for 5 seconds with the power on that connected. Then, the green light is blinking.
Pairing:
When "RFSET" is displayed at both products, if you press the [enter-key] of TCB crane scale, pairing will finish.
[warning] Please check "END" message at both products. (IR -200: green light will be turn on)
If the ending message does not appear, please repeat the pairing.
