With testo 175 measurement values are measured, saved and transmitted to the PC via USB cable or SD card, where they can be read out and analysed with the software testo ComSoft. With the software the data loggers can also be individually programmed. Typical applications testo 175 T1 and testo 175 T2 are optimally suitable for temperature measurements in refrigerators, freezers, cold- storage rooms and cooling shelves. testo 175 T3 records two temperatures at the same time and is most suitable e.g. for monitoring the temperature spreading between feed and return flow in a heating system. testo 175 H1 controls the climatic conditions e.g. in warehouses, offices and in the production area.

This lifetime is calculated on the basis of the following factors:

• Number of connected sensors Since the battery life depends on quite a few other factors, the calculated data can only serve as guide values. The following factors have a negative effect on the battery life:

• longer flashing of the LEDs

• frequent reading out (several times per day) via the SD-card

• extreme fluctuations in operating temperature The following factors have a positive effect on the battery life:

• display switched off The battery capacity reading in the display of the data logger is based on the calculated values. However, the data logger is switched off when a critical voltage level has been reached. It may therefore happen that:

• readings are still recorded, even though the battery capacity reading says "empty".

• the measurement program is stopped, even though the battery capacity reading just before indicated a still remaining battery capacity. In case of an empty battery or a battery change saved readings will not be lost.5 First steps

1. Open the lock with the key (1).

2. Remove the lock (2) from the locking pin.

3. Pull the locking pin (3) out of the holes in the wall

In order to reach the battery life under application temperatures below -10 °C you should use Energizer L92 AAA-size cells.

1. Place the data logger on its front.

2. Loosen the screws on the back of the data logger.

3. Remove the battery compartment cover.5 First steps

5. Place the battery compartment cover on the battery

6. Tighten the screws.

The instructions for the installation and operation of the software can be found in the testo ComSoft 5 Basic instruction manual, which can be downloaded together with the software. The software can be ordered on CD (article-no: 0572 0580), if the download from the Internet is not desired. For testo ComSoft Professional und testo ComSoft CFR: > Insert the CD into the CD-ROM drive.

1. Install the software testo ComSoft.

2. Connect the USB cable to a free USB port on the PC.

3. Loosen the screw on the right side of the data logger.

The display function can be switched on/off via the software testo ComSoft. Depending on the operating status, various information may be shown in the display. A detailed representation of the information that can be called up can be found under Menu overview, page 48. For technical reasons the display speed of liquid crystal displays becomes slower at temperatures below 0 °C (approx. 2 seconds at -10 °C, approx. 6 seconds at -20 °C). This has no influence on the measuring accuracy. testo 175 T1

However, do not apply force! > Make sure that the plugs are firmly connected to the data logger or that the connections are closed with blanking plugs. > Ensure correct positioning of the sensor to avoid disturbing influences affecting the measurement. > testo 175 T3: Always make sure that you connect the sensor configured (via the software testo ComSoft) to the individual sockets. The numbers of the connections are printed on the housing. Pos: 33 /TD/Produkt verwenden/testo 174-neu/ Hinweis Datenlogger programmieren @ 5\mod_126 4769275750_79.doc @ 56853 @ 7.2. Programming data logger In order to adapt the programming of your data logger to your individual requirements, you require the testo ComSoft 5 Basic software. It is available in the Internet as a free download requiring registration www.testo.com, International, Service&Support | Download Center. The instructions for the installation and operation of the software can be found in the testo ComSoft 5 Basic instruction manual that is downloaded together with the software.

The menu overview shows exemplary display representations of the data logger testo 175-T2. The display must be switched on to be able to show the corresponding indications. This is accomplished with the software testo ComSoft. The indication in the display is updated according to the programmed measurement rate. Only readings from active channels are displayed. The channels are also activated via the software testo ComSoft. The symbols for upper or lower alarm value light up in operating states Rec and End, if the programmed alarm value has been exceeded or fallen short off. After 10 seconds without operating a key the display will return to its initial state.7 Using the product

The scope of delivery does not include mounting materials (e.g. screws, wall plugs). ✓ The data logger has been removed from the wall bracket.

1. Position the wall bracket at the desired place.

2. Use a pen or something similar to mark the location for

the fastening screws.

3. Prepare the fastening location in accordance with the

fastening material (e.g. drill hole, insert wall plugs).

✓ The wall bracket has been mounted.

1. Slide the data logger into the wall bracket (1).

2. Push the locking pin (2) through the holes in the wall

3. Fasten the lock (3) on the locking pin.

7.6. Reading out measurement data

The measurement data remain stored in the data logger after they have been read out and can therefore be read out several times. The measurement data will only be deleted when the data logger is reprogrammed.

1. Connect the USB cable to a free USB port on the PC.

2. Loosen the screw on the right side of the data logger.

Use a coin for this purpose.

5. Read out the data logger and process the read out

data, see separate operating instructions testo ComSoft. Via SD card

1. Loosen the screw on the right side of the data logger.

Use a coin for this purpose.

3. Push the SD card into the SD card slot (2).

4. Hold [Go] depressed for longer than 2 seconds.

- The display shows CPY (testo 175 T1) or COPY (testo 175 T2, testo 175 T3, testo 175 H1). - The yellow LED lights during the copying process. - The green LED flashes twice and after the copying process the display shows OUT.

5. Remove the SD card.

6. Insert the SD card into the SD card slot on the PC.

7. Process the read out data, see separate operating

The battery change stops the currently running measurement program. However, stored measurement data are preserved.

1. Read out stored measurement data, see Reading out

measurement data, page 52. ✓ If it is no longer possible to read out the saved measurement data because the battery capacity is too low: > Change the batteries and read out the stored measurement data after.

2. Place the data logger on its front.

3. Loosen the screws on the back of the data logger.

4. Remove the battery compartment cover.8 Maintaining the product

5. Take the empty batteries out of the battery

6. Insert three new batteries (type AAA). Observe the

Only use new branded batteries. If a partially exhausted battery is inserted, the calculation of the battery capacity will not be performed correctly. In order to reach the battery life under application temperatures below -10 °C you should use Energizer L92 AAA-size cells.

7. Place the battery compartment cover on the battery

8. Tighten the screws.

The data logger needs to be reconfigured. For this purpose the software testo ComSoft must be installed on the computer and a connection to the data logger must be set up.

9. Connect the data logger to the PC with a USB cable.

10. Start the software testo ComSoft and set up a

connection to the data logger.
