Introduction
The Soehnle Luggage Travel Scale Model 66172 is designed to help you accurately weigh your luggage, preventing unexpected overweight baggage fees. Its compact and lightweight design makes it an ideal travel companion. This digital scale features an easy-to-read LCD display and a sturdy carrying strap, capable of weighing items up to 110 pounds (50 kg) with 0.2-pound (100g) increments. It also includes an add-weight function and unit conversion between kilograms, pounds, and stone.
Setup
Battery Installation
The scale requires one 3-volt Lithium Metal battery (CR2032), which is included. To install or replace the battery:
- Locate the battery compartment on the underside of the scale.
- Use a small Phillips-head screwdriver to open the battery compartment cover.
- Insert the CR2032 battery, ensuring the positive (+) side faces upwards.
- Securely close the battery compartment cover.
Initial Power On
Press the power button (usually marked with a circle or 'ON/OFF') to turn on the scale. The display will show '0.00' or '8888' briefly before settling on '0.00' with the current unit of measurement (e.g., kg, lb, st).
Operating Instructions
Weighing Luggage
To accurately weigh your luggage:
- Ensure the scale is powered on and displays '0.00'.
- Attach the sturdy carrying strap of the scale to the handle of your luggage. Make sure the connection is secure.
- Lift the scale and luggage together, holding the scale horizontally and steadily.
- Wait for the display to stabilize. The weight will be shown on the LCD screen.
- Lower the luggage gently. The weight reading will typically hold on the display for a few seconds after the load is removed.

Unit Conversion
To switch between measurement units (kilograms, pounds, or stone):
- With the scale powered on and displaying '0.00', press the 'UNIT' button (often the same as the power button, or a separate button if available).
- Each press will cycle through the available units: kg → lb → st. Select your preferred unit before weighing.
Add-Weight Function (Tare)
The add-weight (tare) function allows you to weigh multiple items consecutively without removing the previous item from the scale. This is useful for adding items to a bag and measuring the incremental weight.
- Weigh the first item as described above.
- While the first item is still on the scale and its weight is displayed, press the 'TARE' button (often the same as the power/unit button, or a dedicated button). The display will reset to '0.00'.
- Add the next item to the scale. The display will show the weight of only the newly added item.
- Repeat as needed.
Maintenance
Cleaning
To clean your scale, wipe it with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
Storage
Store the scale in a cool, dry place away from direct sunlight and extreme temperatures. Remove the battery if the scale will not be used for an extended period to prevent leakage.
Troubleshooting
- Display shows 'Lo' or is dim: The battery is low and needs to be replaced.
- Inaccurate readings: Ensure the scale is held steadily and horizontally during weighing. Avoid touching the luggage or the strap while weighing. Recalibrate by turning off and on, then re-weigh.
- Display shows 'Err' or 'O-Ld': The luggage exceeds the maximum weight capacity of 110 lbs (50 kg). Remove some weight to prevent damage to the scale.
- Scale does not turn on: Check if the battery is correctly installed and has sufficient power. Replace the battery if necessary.
