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.

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.
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.

7 Maintaining the product
31
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.
- The data logger is once again ready for use.
