Product Name: Leea Harris Portable – Model: GDP E304

Overview: The GDP E304 Leea Harris Portable is a ruggedized, battery-operated economic data terminal designed for field economists and policy makers. By integrating the Gross Domestic Product (GDP) calculation engine (E304 standard) into a handheld form factor, the Leea Harris enables users to collect expenditure, production, and income data without returning to a central server.

Use Cases:

Adopting this technology requires more than purchasing the hardware. Here is a step-by-step integration guide for your lifting team.

Step 1: Pre-Use Verification Every morning, perform a “zero check” with no load attached. The GDP display should read 0.00 ±0.1%. If not, use the auto-tare function. Document this in your daily lifting log.

Step 2: Attachment Protocol Always use certified shackles that match the load cell’s eye diameter. The Harris Portable design includes a pivoting eyebolt to prevent bending moment errors. Never hammer the shackle pin into place; the E304 load cell is accurate only when the force is axial.

Step 3: Live Monitoring vs. Peak Recording For dynamic lifts (e.g., lifting a boat from choppy water), enable the peak-hold mode. For static proof tests, watch the live display as you gradually apply hydraulic pressure. The GDP algorithm filters out vibration noise caused by wind or pump pulsation. gdp e304 leea harris portable

Step 4: Data Export At the end of the lift, connect the unit via USB-C or Bluetooth to the Harris Logbook software. The software automatically appends the LEEA calibration certificate number, date, time, peak load, and duration. This creates an immutable record for your quality management system (ISO 9001).

Q: Can I use the GDP E304 LEEA Harris Portable for overhead lifting as a primary safety device? A: No—this is a monitoring device, not a safety device. It tells you the load; it does not prevent overload. You still need a crane with a functional overload limiting device (OLD). However, the GDP E304 is ideal for verifying that the OLD is working correctly.

Q: Is the “Harris Portable” waterproof enough for offshore use? A: The standard unit is IP67, which is rain and splash-proof. For continuous immersion or saltwater deck use, you need the optional “Marine” variant with IP68 connectors and a sacrificial zinc anode.

Q: How does the LEEA certificate come with the GDP E304? A: Each new unit ships with a signed LEEA Certificate of Conformity and a calibration report showing as-found and as-left data. Keep this in your lift file. If you lose it, you can request a digital copy from the Harris serial number database for a small fee. Best for: A catalog, user manual, or product listing

Q: Can this unit measure compression as well as tension? A: Most GDP E304 LEEA Harris Portable units are tension-only (load cells). If you need compression (e.g., weighing a silo or testing a jack), you require a different model—specifically the GDP C305 series. Do not invert a tension load cell to measure compression; it will void the calibration.
