Questions and Answers

    Why won't my Jadever Scales power on?
    • J
      Jeremiah GonzalesAug 16, 2025
      If your Jadever Scales fail to power on, several issues could be the cause. It might be due to a defective lead-acid battery. To check, remove the battery and try powering on the scale using the charging transformer. If it powers on, the battery is likely the problem. Alternatively, the charging transformer itself may be faulty; try using a known working transformer. Other potential causes include a fault in the CPU or crystal oscillating circuit (11.0592M), the LCD or related LCD circuit, or a power circuit fault. You should also check the ON/OFF switch for malfunction and replace it if necessary.

    Why are my Jadever JCL Scales not charging properly?
    • T
      Thomas HarperAug 19, 2025
      If your Jadever Scales are experiencing charging failure or a shortened service life, several components could be at fault. Start by checking the lead-acid battery; it might be defective. Remove the battery and try powering the scale with a charging transformer to see if the battery is the issue. Also, the charging transformer itself could be the problem; try using a normal charging transformer. Other potential issues include defective components or a power circuit problem. Look for a blown fuse, and if found, replace it. Inspect components like D2/ Q1(D313)/U5 Q2/Q3/Q4 and replace any that are defective. The charge lamp may also be defective or have reversed polarity.

    How to fix a poor LCD display on Jadever JCL?
    • A
      Andrea WrightAug 22, 2025
      If the LCD display on your Jadever Scales is poor, the LCD itself may be defective. After confirming there isn't a broken board line or short circuit between the LCD and other conducting objects, replace the LCD directly. Alternatively, a component or part may be defective; check CP19/LM2930 and replace any defective components. An IC (PT6554) related circuit fault could also be the cause; in this case, check the IC (PT6554) related circuit and replace the defective one.

    What to do if my Jadever Scales are weighing incorrectly?
    • D
      Diana RobertsAug 26, 2025
      If your Jadever Scales are weighing incorrectly, the component LM2931, AD5530, or 4.9152M might be defective and require replacement. Another potential cause is a load cell malfunction, which would also require replacement.

    Why doesn't the buzzer work on my Jadever JCL?
    • E
      Ethan JeffersonAug 28, 2025
      If the buzzer on your Jadever Scales isn't working, Q11 or Q8 may be defective; check and replace them if necessary. Alternatively, the buzzer itself may be defective, or there could be a fault in the buzzer circuit, requiring replacement.

    How to troubleshoot keypad dysfunction on Jadever Scales?
    • C
      Christopher AcevedoAug 31, 2025
      If the keypad on your Jadever Scales is not functioning correctly, the keypad or keypad circuit might be faulty; check and replace them if needed. Another possible cause is a CPU or CPU program issue; in this case, check and replace the CPU. Additionally, component 74LS139 could be defective; check and replace it if necessary.

    What causes memory dysfunction in Jadever Scales?
    • M
      Melissa LopezSep 3, 2025
      If your Jadever Scales are experiencing memory dysfunction, the component 24C02, R29, R30, R31, or CP18 may be defective. Check these components and replace any that are faulty.

    Why do I get messy code in printouts from my Jadever JCL Scales?
    • J
      Joshua Underwood Jr.Sep 6, 2025
      If you are getting messy code in the printouts from your Jadever Scales, it could be due to a wrong setting. Check and reset the external device, baud rate, and print mode. The RS-232 board could also be defective, so check and replace it if necessary. A bad connection between the RS-232 board and the main board could also be the problem; check and replace the wire connection. Finally, the external device itself may be defective and require maintenance or replacement.

    What to do if the LCD backlight on my Jadever Scales has no function?
    • R
      richard36Sep 9, 2025
      If the LCD backlight on your Jadever Scales is not functioning, the LCD backlight itself may be defective and require replacement. Alternatively, a component may be defective; check and replace Q9, CPU, P71, R72, R73, R74, R75, and R76.

    What does the battery symbol mean on my Jadever JCL?
    • H
      hebertvictorSep 12, 2025
      If a battery symbol appears on your Jadever Scales, it could indicate insufficient cell voltage. Try recharging the battery. If the voltage of the battery is lower than 5.7V and the battery indication lamp is still green, replace the rechargeable battery immediately. A defective component could also be the cause; check and replace R34, R35, R36, and Q10. Finally, a bad connection between R34 and LM2930 could be the issue; repair the wire connection between these components.
