MTM-A quality type level meter full-scale calibration operation: First, place the sensing pen at the 11 o'clock position, remove it after P0 is displayed, then place the sensing pen at the 11 o'clock position again, remove it after P2 is displayed, then place the sensing pen at the 5 o'clock position to enter the P2 full-scale calibration interface, remove the pen after entering the menu, then place the sensing pen at the 5 o'clock position again for full-scale calibration. When the middle value matches the top right value, the full-scale calibration is successful. Place the sensing pen at the 11 o'clock position to exit the menu, and after the 10-second countdown ends, 100% will be displayed, completing the full-scale calibration.

MTM-A quality type level meter unit change operation: First, place the sensing pen at the 11 o'clock position continuously, remove it after P0 is displayed, place the sensing pen at the 11 o'clock position again, remove it after P5 is displayed, place the sensing pen continuously at the 5 o'clock position to enter the P5 menu to change the unit interface, the current display unit is litres, change it to percentage, place the sensing pen continuously at the 5 o'clock position, remove it after the screen displays the percentage, place the sensing pen at the 11 o'clock position to exit the unit change interface, wait for the 10-second countdown to end, and the unit change is complete.

MTM-A quality type level meter medium change operation: Place the sensing pen at the 11 o'clock position, remove it after P0 is displayed, place the sensing pen at the 5 o'clock position, enter the P0 menu and then remove it, the current displayed medium is liquid nitrogen, place the sensing pen at the 5 o'clock position for the medium change operation, change the medium to carbon dioxide, remove the sensing pen after carbon dioxide is displayed, place the sensing pen at the 11 o'clock position to exit the interface, wait for the 10-second countdown to finish, the medium change operation is complete.

MTM-A quality-type liquid level meter volume adjustment operation: Place the sensing pen continuously at the 11 o'clock position, and remove it when P0 is displayed. Then place the sensing pen at the 11 o'clock position again and remove it when P10 is displayed. P10 is the volume modification menu. Place the sensing pen continuously at the 5 o'clock position to enter the P10 volume replacement interface. The current volume displayed is 850 litres. Place the sensing pen at the 11 o'clock position, move it one step on the progress bar and remove it. At this point, the units digit “0” flashes. You need to change “850” to “900”. The units digit 0 does not need to be changed. Place the sensing pen at the 11 o'clock position to modify the tens digit. When the number flashes, remove the pen. Place the sensing pen continuously at the 5 o'clock position, change the 5 to 0, and remove it. Then place the sensing pen at the 11 o'clock position, and when the number flashes, modify the hundreds digit. Place the sensing pen at the 5 o'clock position, change the “8” to “9”, and remove it. Finally, place the sensing pen continuously at the 11 o'clock position to exit the menu. Wait for the 10-second countdown to finish, and the volume modification is successful.

Deleetech SMTD differential pressure meter trigger operation: Place the induction pen at the 3 o'clock position on the SMTD screen, remove the induction pen after the screen flashes, wait for the progress bar to finish flashing, and "E49" will pop up, indicating the trigger is complete.

SMTD differential pressure meter medium change procedure: Keep the sensing pen at the 9 o'clock position, remove it once P0 is displayed, then place the sensing pen at the 3 o'clock position to enter the P0 menu, change the medium to argon, repeatedly tap the sensing pen at the 3 o'clock position to switch the medium until argon is displayed, then keep the sensing pen at the 9 o'clock position and wait for the 10-second countdown to complete. Medium change successful.

SMTD differential pressure gauge diameter adjustment operation: Place the induction pen at the 9 o'clock position until P0 is displayed, then remove it. Place the induction pen again at the 9 o'clock position until P15 is displayed, then remove it. Place the induction pen at the 3 o'clock position to enter the P15 menu. The current screen shows a diameter of 2110mm, which needs to be changed to 1700mm. Place the induction pen at the 9 o'clock position to switch, then place it at the 3 o'clock position to modify the number. Continue to switch at the 9 o'clock position. Keep the induction pen at the 3 o'clock position and wait until the number 7 is displayed, then remove it. Then place the induction pen at the 9 o'clock position and hold it at the 3 o'clock position to change the thousandth digit to 1, then remove it. Finally, keep the induction pen at the 9 o'clock position to exit, wait for a 10-second countdown to end, and the diameter adjustment is complete.

SMTD differential pressure gauge volume adjustment operation: Place the sensing pen at the 9 o'clock position, after P0 is displayed, move it away, then place the sensing pen again at the 9 o'clock position, after P10 is displayed, move it away, keep the sensing pen at the 3 o'clock position to enter the P10 menu, the current display shows 20 cubic units, which needs to be changed to 31 cubic units. Place the sensing pen at the 9 o'clock position for the swap operation, after multiple touches to swap, change 0 to 1, then place the sensing pen at the 9 o'clock position to swap, place it at the 3 o'clock position to change 2 to 3, finally keep the sensing pen at the 9 o'clock position to exit, wait for the 10-second countdown to finish, the volume change is successful.

SMTD differential pressure gauge unit change procedure: Place the sensing pen continuously at the 9 o'clock position, remove it after P0 is displayed. Place the sensing pen again at the 9 o'clock position, remove it after P5 is displayed. Keep the sensing pen at the 3 o'clock position to enter the P5 menu, use the sensing pen at the 3 o'clock position to switch the unit to kilograms, then place the sensing pen continuously at the 9 o'clock position and wait for the 10-second countdown to complete. The unit change is successful.

Deleetech MTU series vehicle-mounted liquid level transmitter upgrade procedure: First, open the after-sales APP software (e-CAL) and register an account. After registration, click login. After logging in, use the read function to confirm that the instrument is powered normally. Place the phone on the instrument when clicking read; if numbers can be read, it indicates that the instrument is powered normally. Then move the phone away. Select the upgrade function and find the required software version number for the upgrade. Taking FW1211 as an example, click "1211", then place the phone on the instrument again, click "1211" once more, and click OK when the prompt appears. Keep the phone close to the instrument until the data packet is completely written. After writing is complete, a configuration success message will appear. After successfully reading, the version number FW1211 will be displayed, indicating the instrument has been successfully upgraded.
