3.1 Use
The testo 174 data loggers are used for storing and reading out individual readings and series of measurements.
Readings are measured and stored with the testo 174 and transmitted to the PC via the interface, where they can be read out and evaluated using the testo ComSoft software. The data logger can also be programmed individually via the software.
Examples of applications
testo 174T is ideally suited for temperature measurement in in refrigerators, freezers, cold rooms and cold shelves.
testo 174H monitors the climatic conditions, e.g. in warehouses, offices and in the manufacturing sector.

7.1 Changing the batteries
instruction manual.
The running measurement program is stopped when the battery is changed. The stored data are preserved, however.
1. Read out stored data, see testo ComSoft software instruction
manual.
If it is no longer possible to read out the stored data because
the battery capacity is too low: > Change batteries and then read out the stored data.
2. Place the data logger on its front.
3. Open battery cover on the rear of the data logger by turning to
the left. Use a coin for this.
30
4. Remove empty batteries from the battery compartment.
5. Insert two new batteries (3 V button cells, CR 2032 lithium) into
the instrument so that the + pole is always visible.
Page 14
7 Maintaining the product
Only use new branded batteries. If a partially used battery is inserted, the calculation of the battery capacity is not performed correctly.
6. Place battery compartment cover on the battery compartment and close by turning to the right. Use a coin for this.
- The current reading is shown on the display.
The data logger must be reconfigured. To do so, the testo ComSoft software must be installed on the computer and a connection to the data logger must be set up (see Connecting data logger to PC page 26).
7. Slide the data logger into the bracket of the interface.
8. Start testo ComSoft software and create a connection to the data logger.
9. Reconfigure data logger or install the old stored configuration, see separate testo ComSoft instruction manual.
7.2 Cleaning the instrument
- The data logger is once again ready for use.
CAUTION
Damage to the sensor!
