5. Operating Instructions
The UHADO-16 data logger is designed for straightforward operation. Below are instructions for starting, stopping, and reviewing data directly on the device.
5.1. Starting the Logger
To begin logging, press and hold the START/MARK button until the display shows REC+ or RECORDING. If the logger is pre-configured for a delayed start, it will show dts (date/time start) or St (start delay) before logging begins. If configured for a push-button start, READY will display until the button is pressed.
5.2. Reviewing Data During Logging
During active logging, the display will show the current temperature and humidity. You can review the minimum and maximum recorded values by briefly pressing the STOP/REVIEW button. Each press will cycle through the current reading, maximum temperature (MAX), and minimum temperature (MIN). A checkmark indicates no alarm excursions, while an arrow or cross symbol indicates an alarm threshold has been triggered or an alarm event occurred.
5.3. Stopping the Logger
If the logger is configured for manual stopping, press and hold the STOP/REVIEW button until STOPPED appears on the display. Logging will cease, and the recording indicator will disappear. After stopping, a checkmark or cross symbol will indicate if any alarm events occurred during the entire logging period.
5.4. Marking an Event
During logging, a brief press of the START/MARK button will place an inspection mark in the data. The MARK symbol will appear on the display and remain until the next reading is taken. This mark will be visible in the downloaded data, indicating a specific event or inspection point.

6. Maintenance
6.1. Battery Replacement
The UHADO-16 uses a user-replaceable CR2032 coin cell battery. When the battery indicator on the display shows low power, replace the battery promptly to ensure continuous and accurate logging. Refer to the detailed instructions provided with the device for safe battery replacement procedures.
7. Troubleshooting
If you encounter any issues with your LogTag UHADO-16, consider the following:
- Device Not Responding: Check the battery level. If low, replace the CR2032 battery.
- Data Transfer Issues: Ensure the logger is correctly inserted into the USB port or interface cradle. Verify that the LogTag Analyzer software is installed and running.
- Inaccurate Readings: Ensure the logger is placed in an environment where air can circulate freely around it and is not exposed to direct heat sources or extreme conditions beyond its specified operating range.
- Display Blank: This typically indicates a depleted battery. Replace the battery.
