This manual provides installation, operation, calibration, and maintenance instructions for the Locosc Precision XK3150-Ex electronic weighing instrument…
The Locosc Precision XK3150-Ex is a specialized electronic weighing instrument designed for use in explosive gas and combustible dust environments. It utilizes intrinsic safety design technology and supports two power supply methods: a dedicated explosion-proof battery pack or an intrinsic safety output power source. The device complies with national standards GB12476.1-2013 and GB12476.4-2010, featuring an explosion-proof rating of Ex ibD 21 T130/T190 depending on the power supply used.
This user manual covers essential topics including safety precautions, installation procedures for external power and sensors, basic operations such as zeroing and tare functions, calibration steps, parameter settings, error code troubleshooting, and daily maintenance guidelines. It also details optional features like serial communication (RS232/RS485), 4-20mA analog output, and wireless communication interfaces. This manual is written in Chinese.

The device has an explosion-proof rating of Ex ibD 21 T130/T190, depending on whether it uses a battery or external power.
No, because the lithium battery charger is not designed according to intrinsic safety requirements and cannot be charged in the danger zone.
The added weight should be at least 10% of the maximum scale, with a recommendation of 60% to 80% of the maximum scale.
An ERR5 code indicates EEPROM verification failure; you should recalibrate or replace the PCB board.
