RLP Atex using a load cell

• Once the batteries are fitted the Radiolink should be fitted with the correct shackle for the capacity of the Radiolink.
• The WLL is marked on the front of every Radiolink e.g. Max: 6.5-tonne x 0.001te
• Before using the Radiolink make sure the capacity of the load cell is suitable for the task being undertaken.
• Straightpoint recommends Crosby shackles.
• When using the Radiolink please ensure the operator is positioned at a safe distance but within range and in the direction of the Radiolink radio output.

Avoid shock loads. Do not apply large twisting forces to these devices as it may damage them beyond repair. If using RLP with SW-HHP ATEX handheld please refer to user manual SU3558 for guidance on that product. Remove the device from the test site, clean, and store, ideally in a Straightpoint carry case.
