UNI-T UT330T USB Temperature Data Logger

Introduction
The USB datalogger (Hereinafter referred to as “logger”) is a low power consumption, high-accuracy temperature & humidity device. It has the characteristics of high accuracy, large storage capacity, auto save, USB data transmission, time display and PDF export. It can meet the requirements of various measurements and long-term temperature and humidity recording, and can be used in food processing, cold chain transportation, warehousing and other fields. UT330T is designed with IP65 dust/water protection. UT330THC can be connected to an Android smartphone or computer via the Type-C interface to analyze and export data in the smartphone APP or PC software.

Setting

USB communication

• Download the instruction and PC software according to the attached file, then, install the software step by step.
• Insert the logger into USB port of PC, the main interface of logger will display “USB”. After the computer identifies the USB, open the software to set parameters and analyze the data. (Figure 3).
• Open the computer software to browse and analyze data. As for how to use the software, users can click the help option on the operation interface to find “software manual”.

Parameter configuration

Operations

Starting the logger
There are three starting modes:

1. Press the button to start the logger
2. Start logging through the software
3. Start logging at preset fixed lime
   • Mode 1: Long press the start button for 3 seconds in main interface to start logging. This start mode supports start delay, if delay time is set, the logger will start logging after a delayed time.
   • Mode 2: Start logging through the software: On PC software, when parameter setting is completed, the logger will start logging after user unplugs the logger from the computer.
   • Mode 3: Start the logger at preset fixed time: On PC software, when parameter setting is completed, the logger will start logging at preset time after user unplugs the logger from the computer. Mode 1 now is disabled.

Warning: please replace the battery if low power indication is on.

Stopping the logger
There are two stop modes:

1. Press the button to stop.
2. Stop loggina through the software.
   1. Mode 1: In main interface, long press stop button for 3 seconds to stop the logger, If “Stop with key” is not checked in the parameter interface, this function cannot be used.
   2. Mode 2: After connecting the logger to the computer, click the stop icon on the main interface of the computer to stop logging.
   3. Recording mode Normal: The logger automatically stops recording when the maximum number of groups is recorded.

Function Interface 1
UT330TH/UT330THC:Short press stop button to switch between temperature and humidity in the main interface. In the main interface, short press the Start button to step through measured value, Max, Min, mean kinetic temperature, upper alarm value, lower alarm value, current temperature unit, optional temperature unit (long press the Start and Stop buttons at the same time to switch between the units), and measured value.
Users can short press stop button at any time to go back to the main interface. If no button is pressed for 10 seconds, the logger will enter the power-saving mode.

Marking
When the device is in logging state, long press start button for 3 seconds to mark the current data for future reference, the mark icon and current value will flash 3 times, total number of mark value is 10.

Function Interface 2
In the main interface, press the start button and stop button together for 3 seconds to enter the Function Interface 2, short press start button to view: Y/M/D, device ID, maximum numbers of remaining storage groups, numbers of marking groups.

Alarm State
When the logger is operating,
Alarm disabled: Green LED flashes every 15 seconds and main interface displays √.
Alarm enabled: Red LED flashes every 15 seconds and main interface displays x.
No LED lights when the logger is in stopping state.

Note: The red LED will also flash when the low voltage alarm appears. Users should save the data in time and replace the battery.

Viewing data
Users can view the data in stop or operating state.

• View the data in stop state: Connect the logger to the PC, if the LED flashes at this time, the PDF report is being generated, do not unplug the logger at this time. After the PDF report is generated, users can click the PDF file to view and export the data from the computer software.
• View the data in operating state: Connect the logger to the PC, the logger will generate a PDF report for all previous data, at the same time, the logger will continue logging data and it can only generate a PDF report with new data the next time.
• Alarm setting and result
  Single: The temperature (humidity) reaches or exceeds the set threshold. If the continuous alarm time is not less than the delay time, the alarm will be generated. If the reading returns to normal within the delay time, no alarm will occur. If the delay time is Os, an alarm will be generated immediately.
  Accumulate: The temperature (humidity) reaches or exceeds the set threshold. If the accumulated alarm time is not less than the delay time, the alarm will be generated.
