| Backlight control | Press Up or Down Arrow button to adjust the backlight luminance |
| Induction intensity control | Detector automatically increases or decreases the signal amplification factor according to the intensity of the electric field, facilitating the phase checking in a place of intensive lines |
| Data maintenance | Press HOLD button under testing mode to maintain the data, and then press HOLD button again to cancel the maintenance |
| Exit function | Press ESC button to exit from current interface and return to the upper directory |
| Data reference | Press ENTER to determine data reference mode, and press Arrow button to refer to all the stored data |
| No-signal indicator | When the receiver does not receive the transmission signal, it dynamically displays "----" symbol |
| Automatic shutdown | About 15mins after startup, the instrument will be automatically shut down to reduce battery consumption |
