Why are my Jadever JCL-6K showing wrong calibration weights?
If you encounter issues with calibration on your Jadever Scales, ensure you are using the correct test weights. The calibration value should also be below the full load capacity of the scale.
What to do if Jadever JCL-6K Scales show overload condition?
If your Jadever Scales display shows an overload condition, remove the item that is causing the overload.
What to do if accumulated weighments exceed display range on Jadever Scales?
If the accumulated number of weighments on your Jadever Scales exceeds the display range, delete the exceeding weights to resolve the issue.
Why initial zero point exceeds 30% of full load on Jadever JCL-6K Scales?
If the initial zero point exceeds 30% of the full load on your Jadever Scales: 1. Remove any obstructions under the pan. 2. If the issue persists, it may be necessary to replace the load cell or contact the maintenance department.
What causes Jadever JCL-6K Scales to exceed tare or pre-tare range?
If your Jadever Scales exceed the tare or pre-tare range, ensure that the tare value is within the range of 0 to the full load.
Why do Jadever Scales exceed the zero range?
If your Jadever Scales exceed the zero range, ensure that the item on the pan is within 2% of the full load.
Why won't my Jadever JCL-6K power on?
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 Scales not charging properly?
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-6K?
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 JCL-6K are weighing incorrectly?
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.
