What to do if TRANSTEK Scales cannot analyze body fat?

  Danielle MooreAug 13, 2025
  If the TRANSTEK Scales cannot analyze body fat, total body water, muscle mass, and bone mass, make sure you are barefoot on the platform, maintaining full contact with the electrodes. Also, assign a User ID following the instruction in Set Up Your Profile, because the system may not be able to identify the possible User ID with the most similar data, or the user fails to select the User ID from what the system found.

  If the LCD on your TRANSTEK Scales doesn't display anything when you turn it on, it could be due to missing or worn-out batteries. Install the batteries referring to the section 'Insert the Batteries' or replace all four batteries at the same time with authorized batteries.

  If you're getting abnormal measuring results from your TRANSTEK Scales, such as values that are too high or too low, or a huge difference between two recent measurements, make sure you step on the platform barefoot and stand still. Also, ensure the device is placed on a flat, hard surface, not on a soft ground like a carpet or a rugged surface.

  If you're getting abnormal measuring results from your TRANSTEK Scales, such as values that are too high or too low, or a huge difference between two recent measurements, wipe your feet with a damp cloth, keeping them slightly damp when starting measurement, because either your hands or your feet may be too dry.

This document describes the Transtek Body Fat Analyzer BF-1256-B1, a device designed for personal health management in a domestic setting.

Function Description:

The Transtek Body Fat Analyzer BF-1256-B1 measures weight and uses Bio-electrical Impedance Analysis (BIA) technology to estimate body fat, total body water percentage, bone mass, and muscle mass. It is intended for use by generally healthy children aged 10-17 years old and healthy adults. The device provides a seamless way to manage personal health data, with the capability to transmit measurement results to a smartphone via Bluetooth 4.0. The BIA technology involves a small, imperceptible electrical current flowing through the body to detect bio-impedance, which is then used to calculate body composition. This method is described as cheap, safe, non-invasive, toxic-free, and harmless. The device can also function as a conventional weight-only scale.

Usage Features:

Multi-User Support: The BF-1256-B1 supports up to eight users, allowing each to set up a personal profile including Gender, Stature, and Age. User IDs (P1 to P8) can be assigned.
Profile Setup: After battery installation, users can set their User ID, Gender (including an athlete mode for ages 15-85), Stature (range: 100 cm to 220 cm / 3'3.5"~7'2.5" ft), and Age (range: 10 to 85 years old).
Measurement Unit Selection: The device allows selection between pound, kilogram, and stone units using the "UNIT" button.
First Measurement: Requires stepping onto the platform barefooted and standing still until the measurement is complete. Results for Body Fat, Total Body Water, Muscle Mass, and Bone Mass are displayed sequentially three times.
Daily Measurement: Utilizes "SENSE ON" patent technology for automatic power-on when stepping on the platform. The system automatically identifies the user based on history records and displays results. If multiple users have similar records, the system prompts for user selection.
Body Fat Indicator: A progress bar on the LCD displays the body fat level (Low, Normal, High, V. High) after analysis.
Data Transmission: When successfully paired with a smartphone via Bluetooth, measurement data is automatically transmitted to the mobile device. Data is transmitted only when results are attached to a specific User ID. If transmission fails, data is temporarily stored and transmitted during the next successful connection.
Pair-up Process: Involves turning on Bluetooth and the app, then pressing and holding the "UNIT" button on the scale. The LCD shows alternating symbols during pairing, indicating success or failure.
Weight Only Operation: The scale can be used as a conventional weight scale without special programming. After initialization, users can simply step on to measure current weight.
Safety Information: The manual provides detailed safety and usage information, including contraindications for pregnant women, individuals with implanted electronic devices, and those with acute or chronic illnesses affecting water levels. It also advises on proper measurement conditions (flat, hard surface, bare feet, clean/damp feet) and avoiding measurement after strenuous activities.

Maintenance Features:

Cleaning: Use a dry soft cloth to wipe dust. For dirt, use a wet soft cloth (dipped in water and wrung out), then dry with a soft cloth. Do NOT wash the device with water or immerse it. Do NOT use propellant, abrasive, or other chemicals.
Troubleshooting: The manual includes an "Error Prompt" section to address common issues such as overload, low battery, pairing failure, abnormal measurement results (too high/low, huge difference), and inability to analyze body composition. Solutions include stopping use, replacing batteries, checking Bluetooth connection, correcting posture, and placing the scale on a flat, hard surface.
Battery Replacement: When the low battery symbol appears, all four AAA batteries should be replaced simultaneously with new, authorized batteries. Worn batteries are hazardous waste and should be disposed of according to local ordinances. Batteries should be removed if the unit is not used for a prolonged period.
Warranty: Transtek offers a FIVE-year warranty from the date of retail purchase, covering defects in materials and workmanship under normal use. The warranty does not cover damages from misuse, abuse, unauthorized repairs, improper operation, or failure to provide recommended maintenance. For warranty service, the device should be returned in its original package with the store receipt.
EMC Guidance: The device requires special precautions regarding electromagnetic compatibility (EMC) and should be installed and used according to the provided EMC information. It advises on maintaining a separation distance from wireless communication equipment to mitigate interference.
