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.

Instructions for modifying the volume on the Deleetech 8051 instrument in Jiangsu: Place the induction pen at the 9 o'clock position on the instrument. The interface will display a hypothetical value of 1500. Tap the 9 o'clock position repeatedly to perform the 'units, tens, hundreds' shift operation; the flashing '0' indicates the shift was successful. When the hundreds digit '0' flashes on the screen, place the induction pen at the 3 o'clock position and change the digit 0 to 5. Remove the induction pen once the modification is complete. Lightly tap the 9 o'clock position with the induction pen to perform the 'thousands' shift operation (the thousands digit is shown in the top right corner of the screen) and change the thousands digit from 2 to 1. Place the induction pen at the 3 o'clock position to complete the digit change and remove the pen after the screen shows 1. After finishing the volume modification, place the induction pen at the 9 o'clock position, exit the P10 volume modification interface, and then remove the pen. Wait for the 10-second countdown to complete, and the instrument volume modification process will be finished.

MTU Instrument Reverse Calibration Operation Guide: First, ensure that the instrument is in a normal power supply state. Once confirmed, open the after-sales version of the e-CAL APP. Enter the APP backend interface and click on the modification option. Perform the reverse calibration operation when the cylinder is in a full liquid state. Click on reverse calibration, and the interface will display four parameters, three of which can be filled in according to the cylinder nameplate. The cylinder's effective volume must be confirmed with the manufacturer before filling in. Cylinder effective volume and sensor increment are mandatory fields. Example parameters: cylinder effective volume 1350 litres, sensor increment 58. After completing the parameter input, click write, place the phone close to the instrument, and wait until the interface displays configuration success, indicating the parameters have been written. Remove the phone and click confirm to complete the MTU instrument reverse calibration operation.

Before operation, ensure the instrument is under normal power supply, open the after-sales version of the e-CAL APP, and enable the mobile phone's NFC function. Tap 'Tools' to enter the tool backend, where various function settings can be configured. CAN bus protocol number: select the corresponding option according to the vehicle manufacturer; for example, for Auman A6, after selection, bring the phone close to the instrument, and the configuration will be complete once the success message is displayed. CAN bus device ID: select according to the cylinder number installed on the instrument; for instance, if installed on cylinder 2, select cylinder 2, and bring the phone close to the instrument until the success message is displayed to complete the configuration. Alarm functions and the lower limit of the liquid level display can be set according to actual requirements. CAN bus baud rate: select the appropriate parameter according to the instrument model, such as 500K; be sure to confirm with after-sales personnel before setting, and after selection, bring the phone close to the instrument until the configuration is successfully completed. The filter value can be set as needed; consult after-sales personnel before configuration. The above are the instructions for configuring the function settings in the tool section of the e-CAL after-sales APP.

MTM-A Quality Type Level Meter (after interface upgrade) Zero Calibration Operation Guide: Place the sensing pen at the 9 o'clock position and keep it still, then wait until the screen displays P0 before removing it. Lightly tap the 9 o'clock position once to switch the interface from P0 to P1. Place the sensing pen at the 3 o'clock position and keep it still to enter the P1 zero calibration interface, waiting for the values to stabilise. Place the sensing pen at the 3 o'clock position again and keep it still to perform the zero calibration; the digits flashing indicates successful calibration. Place the sensing pen at the 9 o'clock position and keep it still to exit the P1 interface. Wait for the 10-second countdown to finish; zero calibration is complete.

MTM-A Quality Type Level Meter - Full Scale Operation Guide After Calibration Interface Upgrade: Place the induction pen at the 9 o'clock position and hold it still until the screen displays P0, then remove it. Lightly tap the 9 o'clock position twice with the induction pen to switch the interface from P0 to P2. Place the induction pen at the 3 o'clock position and hold it still to enter the P2 full scale interface. Place the induction pen at the 3 o'clock position again and hold it to perform the full scale operation; a blinking value indicates successful calibration. Place the induction pen at the 9 o'clock position and hold it to exit the P2 menu. Wait for the 10-second countdown to finish; full scale completion is achieved.

SMTD differential pressure gauge battery replacement procedure: First, loosen the four screws on the top cover of the instrument, remove the top cover, and unplug the battery connector to take out the old battery. Then, place the new battery in the battery compartment, connect the plug next to the new battery, and organise the supercapacitor wiring before placing it on the side. Finally, reinstall the top cover and tighten the screws, making sure they are secure to prevent water damage to the instrument. After completing these steps, the SMTD differential pressure gauge battery replacement process is fully finished.
