Deleetech MT capacitive level meter unit modification operation guide: Place the induction pen at the 9 o'clock position, and remove it after P0 is displayed; place the induction pen at the 9 o'clock position again, and remove it after P5 is displayed. Place the induction pen at the 3 o'clock position to enter the menu. To set the unit to %, for example, place the induction pen at the 3 o'clock position again and remove it after the target unit is displayed. Then place the induction pen at the 9 o'clock position, wait for 10 seconds to exit automatically, and the unit modification is complete.

Operation to change the medium of the Deleetech MT capacitive level meter: Place the induction pen at the 9 o'clock position to change CO₂ to N₂ as an example, then remove the induction pen. Place the induction pen at the 3 o'clock position to enter the P0 medium modification menu and then remove it. Keep the induction pen at the 3 o'clock position, and the medium will automatically switch. Once the display shows the target medium as nitrogen, remove the induction pen. Finally, place the induction pen at the 9 o'clock position to exit. The main interface will display the corresponding medium, thus completing the medium change.

Deleetech MT capacitive liquid level meter full-scale calibration guide: Place the sensing pen at the 9 o'clock position and then remove it, repeat once at the 9 o'clock position; next, place the sensing pen at the 3 o'clock position and remove it, repeat once at the 3 o'clock position. Wait until the numbers flash to indicate successful calibration. Finally, place the sensing pen at the 9 o'clock position to exit the menu. The screen will display 100%, indicating the full-scale calibration is complete.

Deleetech MT capacitive level meter zero point calibration operation guide: Place the induction pen at the 9 o'clock position and remove it when P0 is displayed; place the induction pen at the 9 o'clock position again and remove it when P1 is displayed. Place the induction pen at the 3 o'clock position to enter the P1 menu, place it at the 3 o'clock position again, and wait for the numbers to flash, indicating the zero point calibration is successful. Then place the induction pen at the 9 o'clock position, remove it when P1 is displayed, wait 10 seconds for automatic exit, and the zero point calibration is complete.

Jiangsu Deleetech MTU Instrument Forward Calibration Operation Guide: First, ensure the instrument is in a normal power supply state and open the after-sales dedicated e-CAL APP. When the cylinder is empty, carry out the forward calibration operation. Enter the APP backend interface, select the modification option, and find the forward calibration function entry. Before calibration, the accurate cylinder effective volume and sensor incremental capacitance parameters must be confirmed. Some parameters can be referred to on the cylinder nameplate. The cylinder effective volume must be verified with the cylinder manufacturer. Among these, the cylinder effective volume and sensor increment are mandatory fields and cannot be left blank; for example, an effective volume of 1350 litres and sensor increment of 370. Ensure parameters are entered accurately. After completing the parameter entry, click write, bring the phone close to the instrument, and wait for the device to read the configuration, with the page loading in a spinning circle. Once loading is complete and the interface shows a successful configuration, click confirm to complete all MTU instrument cylinder forward calibration operations.

Instructions for using the reading function of Jiangsu Deleetech e-CAL After-Sales APP: Before operation, ensure that the instrument is powered normally. New users need to register an e-CAL account using their mobile number. After registration, open the after-sales version of the e-CAL APP. Enter the APP backend interface, enable the phone's NFC function in advance, and click the read button. A prompt will appear saying 'Please place the phone close to the transmitter panel.' Place the phone against the instrument panel and wait for the device to read the data; the page will display a loading circle during this process. Once loading is complete, the page will show 'Reading successful,' completing the operation. The device parameters obtained from this reading can be used to troubleshoot and analyse various instrument faults. If reading fails, do not repeat the operation repeatedly and contact after-sales personnel for assistance in a timely manner.

Jiangsu Deleetech 8051 Instrument Zero Calibration Operation Guide: Place the induction pen continuously at the 9 o'clock position of the instrument and wait until the interface displays P0, then remove the induction pen. Touch the 9 o'clock position of the instrument with the induction pen again to change the interface parameter from P0 to P1. Place the induction pen at the 3 o'clock position of the instrument, enter the P1 zero calibration interface, then remove the induction pen and wait for the interface value to stabilise. Once the value stabilises, place the induction pen again at the 3 o'clock position to perform the calibration; when the interface value flashes, it indicates that the calibration step is complete, then remove the induction pen. Finally, continuously place the induction pen at the 9 o'clock position of the instrument, exit the P1 zero calibration interface and remove the pen, wait for the 10-second countdown to finish, completing the instrument zero calibration operation.

Jiangsu Deleetech 8051 Instrument Full-Scale Calibration Operation Guide: Place the induction pen at the nine o'clock position on the instrument until the interface displays P0, then remove the induction pen. Place the induction pen at the nine o'clock position again and adjust parameter P0 to P2, then remove the induction pen once completed. Place the induction pen at the three o'clock position on the instrument to enter the P2 full-scale calibration interface and then remove the pen, waiting for the interface values to stabilise. Once the values are stable, place the induction pen at the three o'clock position to carry out the full-scale calibration operation. When the interface values flash, it indicates calibration is complete, then remove the penetration pen. Finally, place the induction pen at the nine o'clock position to exit the P2 calibration interface and remove it, waiting for the 10-second countdown to finish. The 8051 instrument full-scale calibration operation is now fully complete.

Jiangsu Deleetech 8051 Instrument Unit Change Operation Guide: Place the induction pen at the 9 o'clock position of the instrument until the interface displays P0, then remove the pen. Place the induction pen at the 9 o'clock position again to switch P0 to P5 (the induction pen can also be tapped multiple times at the 9 o'clock position to change P0 to P5). After P5 is displayed, remove the pen. Place the induction pen at the 3 o'clock position to enter the P5 settings menu, where P5 is the instrument unit modification interface; remove the pen after entering the interface. The device defaults to U-7 (height unit), which needs to be changed to the Kg unit. Place the induction pen at the 3 o'clock position to switch units, and remove the pen once the interface displays KG. Then place the induction pen at the 9 o'clock position to exit the P5 unit modification interface and remove it, wait for the 10-second countdown to finish, and the interface will display Kg, completing the entire instrument unit modification operation.

Jiangsu Deleetech 8051 Instrument Medium Change Operation Guide: Place the induction pen at the 9 o'clock position on the instrument and hold it there until the interface displays P0, then remove the induction pen. Next, place the induction pen at the 3 o'clock position, enter the P0 medium modification interface, and then remove the pen. The instrument's default medium is currently shown as liquid nitrogen. To change the medium to liquid oxygen, place the induction pen at the 3 o'clock position to switch the medium. You can tap the 3 o'clock position multiple times to cycle through the media until the interface displays the desired medium: liquid oxygen. After selecting the medium, place the induction pen at the 9 o'clock position to exit the P0 menu. When the interface displays P0, remove the pen. Wait for the 10-second countdown to complete, and the instrument medium change operation will be finished.
