2.1 Unpacking

• Carefully remove the DLI-4 unit from its packaging.
• Inspect the unit for any signs of damage during transit. If damage is observed, do not use the unit and contact customer support.
• Verify that all components listed in the packing list are present.

2.2 Power Supply

The DLI-4 operates on internal batteries. Ensure batteries are correctly installed according to the polarity markings in the battery compartment. If the display does not illuminate, check battery orientation or replace with fresh batteries.

2.3 Mounting and Connection

The DLI-4 is designed to be integrated into a lifting or pulling system. Use appropriate shackles, hooks, or other rigging hardware (not included) to connect the load indicator securely. Ensure that the hardware used is rated for the maximum load capacity of the DLI-4 (4000 LB) or higher, and that connections are free from obstruction and allow for proper load distribution.

• Connect the top eyelet of the DLI-4 to the lifting mechanism (e.g., crane hook, hoist).
• Connect the bottom eyelet of the DLI-4 to the load to be weighed.
• Ensure all connections are secure and properly seated before applying any load.

• To power off: Press and hold the Power/Zero button until the display turns off. The unit may also have an auto-off feature to conserve battery life.

3.2 Zeroing/Tare Function

The zero/tare function allows you to reset the display to zero, effectively ignoring the weight of any attached rigging or container.

3.4 Hold/Peak Function

This function allows you to capture and hold the maximum weight detected during a measurement, or to simply hold the current reading.

• Press the Hold/Peak button (rightmost button with an 'F' and arrow) to activate or deactivate the hold/peak function. Refer to the on-screen indicators for active mode.

3.5 Taking a Measurement
