5. Operating Instructions

1. Power On/Off: Press the ON/OFF/ZERO button on the scale or the remote control to turn the scale on or off. The green LED display will illuminate.
2. Zeroing the Scale: Before weighing, ensure no load is on the hook. Press the ON/OFF/ZERO button to set the display to zero. This compensates for any minor weight variations.
3. Weighing a Load: Securely attach the item to be weighed to the lower hook. Slowly lift the load. The weight will be displayed on the LED screen.
4. Remote Control Operation: The remote control allows for convenient operation from a distance of 10-15 meters, especially useful in industrial settings.

6. Functions

The YHYWJHY crane scale offers several useful functions:

• Zero: Resets the display to zero. Used to clear the current weight or to zero the scale before weighing.
• Tare: Used to subtract the weight of a container or packaging. Place the empty container on the hook, press the TARE button (if available, otherwise use Zero after placing container), then add the item to be weighed. The display will show only the net weight of the item.
• Hold: Press the HOLD button to freeze the displayed weight. This is useful for recording readings when the load might be unstable or difficult to read directly. Press again to release.
• Overload Alarm/Record: If the load exceeds 120% of the maximum capacity, an alarm will sound, and the display may indicate an overload warning. Remove the excess load immediately to prevent damage.
• Auto Power-off: The scale is equipped with an auto power-off feature to conserve battery life. It will automatically turn off after a period of inactivity.
• Unit Switch (Kg/Lb): Press the Kg/Lb button on the scale or remote control to switch between kilograms (kg) and pounds (lb) units.
