Frequently Asked Questions - BL30 TROTEC

How to install the software provided with the BL30?

Insert the CD into the drive; the installation menu appears automatically. Follow the instructions. Connect the logger via USB to install the driver. The software works under Windows 2000/XP/Vista/7.

What to do if the screen displays '-LO-'?

This message indicates that the temperature/humidity sensor is not properly connected. Open the back of the device and check the sensor connection. If it is properly plugged in, the message disappears. Otherwise, contact Trotec customer service.

How to configure temperature and humidity alarms?

Use the PC software. Click on the configuration icon. In the 'Alarm Setup' field, set the high (HIGH) and low (LOW) values for temperature and humidity. You can also choose the unit (°C/°F) and disable the LEDs.

What is the memory capacity and what happens when it is full?

The device can store up to 32,700 values. When the memory is full, the screen displays 'FULL'. Depending on the configuration, either new data overwrites old data (circular mode) or recording stops. You can choose this behavior in the software.

How to transfer data to a PC?

Connect the logger to the PC via the USB cable. Open the software, click on the download icon. In the window that appears, click 'Download'. The data is then copied and displayed as a graph or list.

Which battery to use and how to change it?

Can I use the device directly connected via USB without battery?

Yes, the logger can be powered directly from the USB port. In this case, the battery is not needed and its life is preserved.

How to reset the device for a new measurement?

After transferring the data, use the software to perform a 'Re-Set' (or 'Reset') function. This erases the old data and prepares the device for a new recording. You can also configure automatic or manual start.

What are the possible causes of inaccurate measurement?

A sudden change in temperature or humidity can cause condensation on the sensors, which distorts the measurements. Let the device acclimate for 15 to 30 minutes. Also check that the sensor is properly connected and that the device is stored vertically.

How to interpret the LEDs (red and yellow)?

The red LED blinks once per minute if temperature thresholds (high or low) are exceeded. The yellow LED indicates humidity threshold exceedance. You can configure the blink frequency (10, 20, or 30 seconds) or disable the LEDs entirely to save battery.

1. Introduction

The temperature and humidity data logger is a particularly sturdy, high-precision measuring instrument, which is characterised by its fast response time. The data logger is already used in many places to monitor both the ambient temperature and the relative humidity and to collect meaningful measurement data.

2. Functions and technical specifications

The data logger is a particularly efficient and handy measuring instrument, which is particularly suitable for longer lasting measurement assignments. The measurement results are stored in the data logger and transferred to the PC via a USB cable. The data can subsequently be read out on the PC. The display shows the current MAX, MIN, TIME, DATE, temperature and humidity values.

▲ Moving the appliance from a cold to a warm environment (and vice versa) can lead to the formation of condensation on the measuring circuitry of the appliance. This physical effect, which cannot be prevented by structural means for any measuring instrument, leads to false measurement values. Depending on the temperature difference, the appliance requires an 'acclimatisation time' of approx. 15 - 30 minutes before the measuring procedure can be resumed.

⚠ Make sure that the data logger is always used/stored in an upright position. This also applies after measurements taken at low temperatures or in highly humid environments. The intention is to avoid any condensation that forms collecting in the appliance; instead, it can escape from the lower part of the appliance. Wait until any moisture which may have formed inside the appliance due to physical processes has completely evaporated before the collected data are read out for evaluation. In order to preserve the batteries, the data logger can also be directly connected to the PC via USB. When connected in this manner it draws its power directly from the PC.

1. Memory space for 32,700 measured values
2. Large, easily readable LCD
3. Freely selectable measurement cycle from 1 sec to 24 hrs

4. Operation

1. The battery symbol indicates the charge capacity of the battery. If the battery is flat, the „flat battery“ symbol appears. Insert a new battery. The lifetime of a conventional battery is at least 3 months. Use exclusively batteries of the same type and of high quality, as otherwise the proper function of the appliance cannot be guaranteed. No liability will be accepted for damage caused by the use of the wrong batteries or batteries of inferior quality.

2. Time displays the current time

3. Date displays the current date

4. The display of time and date changes automatically every 10 seconds

5. MAX: Displays the highest measured value, including the associated date and time.

6. MIN: Displays the lowest measured value, including the associated date and time.

7. REC: This message appears throughout the entire measuring procedure

8. FULL: This message appears if the data memory is full. No further data can be stored.

9. %RH: The measured humidity is displayed as a per percentage.

10. °C: Temperature in degrees Celsius

11. °F: Temperature in degrees Fahrenheit

12. Press the MAX/MIN button in order to display the maximum or minimum values stored during the recording period. The appliances returns to measu

ring mode after 40 seconds if no further button is pressed.

1. The message „-PC-" appears on the display when transmitting the collected measured data to the PC. The data logger returns to measuring mode after data transmission is complete. The currently measured value is displayed and the recording is stopped. Perform a reset; in other words, prepare the data logger via the PC software for a new measurement in order to be able to start a new recording sequence. As a matter of principle, the measured values can only be read from the display. All settings in the data logger are performed exclusively via the software installed on the PC.

2. Alarm function: The LEDs flash once per minute in the case of exceeding or falling below the set limit values. The red LED indicates that the temperature has exceeded/fallen below the user-selected limit values. The yellow LED indicates that the relative humidity has exceeded/fallen below the user-defined limit values.

3. The message „-LO-“ indicates that the sensor for the temperature and humidity is not correctly connected. In this case, you can proceed as follows: Open the back of the appliance and connect the sensor correctly. As soon as the sensor is correctly connected, the message disappears and the appliance is ready for operation once again. If this action is unsuccessful, please contact our customer service department.

Reset time and date

Click on the 🔒 icon in order to reset the time and date. A new window appears. Enter the correct time and the correct date. Then click on „OK“.

Data logger setup

- Click on the icon in the menu. The setup window appears (see below). Proceed as described below in order to set the individual menu items.

• You can set the measurement sampling rate for the data logger with the field „Samprate setup“. Enter the desired number in the left-hand box and the unit of time in the right-hand box.
• You can set the time intervals at which the LEDs flash by clicking the three time intervals (10s/20s/30s=seconds) listed in the „LED Flash Cycle Setup“ field. (If you click „No Light“, the LEDs do not flash when the values exceed/fall below the user-defined limit values. This mode preserves the batteries and ensures a longer life span.
• Click on „Manual“ or „Automatic“ to specify whether the data logger automatically enters recording mode when you close the setup window („Automatic“) or only at a later time („Manual“) by manually pressing one of the two buttons.
• You can configure the upper (HIGH) and lower (LOW) limit values for the temperature and the humidity with the „Alarm Setup“ field. In this field you can also set the temperature units (°C/°F) and deactivate the LEDs.

- By clicking „Circulating Record“ or „No Circulating“, you can decide whether the stored data should be overwritten (Circulating Record) when the memory is full or whether the data logger should not store any further data in this case (No Circulating) and the recording should stop. Click on the SETUP button to save the settings. Click on the „Standard/DEFAULT“ button in order to restore the data logger's factory settings. Click on the „Cancel“ button in order to abort the setup.

⚠️ If the new settings are saved with „Setup“ after the execution of a setup, all previously saved measured values are automatically deleted! In order to prevent such a loss of data, click on the „Cancel“ button during the setup to end the setup procedure prematurely. This way the stored data can still be transferred to another medium (e.g. PC) beforehand. On account of the duration or intensity (e.g. borderline climatic conditions) of an application, the battery life may not be sufficient for the in

tended measurement. Therefore we strongly recommend before performing such an intensive measurement that you check the charge capacity of the batteries and replace them if necessary, in particular if the data are of particular value or the measured values are critical.
