This guide provides an overview of the Lahti Precision TPL-400

The amplifier provides an excitation voltage designed to drive all standard

: Setup for relay modules (like the LR1 set value relay unit) and digital inputs. Accessing the Manual

Use the CALH parameter to set the second calibration point after applying a known reference load. Key Programming Parameters: SEnS: Set the load cell sensitivity (e.g., 2.0 mV/V).

Connect the load cells and power supply according to the terminal diagram in the official user guide .

Supports standard analogue outputs of 4–20 mA and 0–10 V , which are galvanically isolated to prevent interference.

The transmitter can be adjusted via:

Check for mechanical binding or structural friction touching the scale hopper or load cells.

The signal from the load cells is below the calibrated zero range. Check for missing scale components or broken load cell wires. Unstable Display: The weight readings drift or jump wildly.

Regular maintenance prevents drift and unexpected downtime. Keep the load cell assemblies free of debris and inspect cable jackets for wear. Common Error Codes and Resolutions
