Frequently Asked Questions - 175H1 Testo

How to install batteries in the Testo 175H1?

Place the device face down, unscrew the battery compartment cover on the back, insert 3 AAA batteries respecting polarity (use alkaline or Energizer L92 batteries for temperatures below -10 °C), then close and screw back. The display shows 'rST' after power on.

How to connect the data logger to the PC?

Use the supplied mini USB cable. Open the cover on the right side of the device by unscrewing the screw, plug the cable into the mini USB port, then connect the other end to the PC. The testo ComSoft software (free download at www.testo.com/download-center) allows you to program the device and read data.

How to read data via SD card?

Insert an SD card into the slot (cover open). The display shows 'Sd' or 'Sd C Ard'. Press and hold the [GO] button for more than 2 seconds: 'CPY' or 'COPY' appears, the yellow LED lights during copying. Once finished, 'OUT' appears and the green LED blinks. Remove the card and insert it into a PC for transfer.

What do the LED indicators mean?

Red LED blinking: low battery (1x/10s = <30 days, 2x = <10 days, 3x = empty). Red LED 3 blinks after button press: limit value exceeded. Yellow LED 3 blinks: entering Rec mode. Green LED: Wait mode (3 blinks) or SD copy end (2 blinks). Green/yellow/red LED in sequence: battery change in progress.

How to start or stop a recording?

To start: ensure the device is in Wait mode and the start criterion 'Start by key' is programmed, then press [GO] for about 3 seconds. 'Rec' appears. To stop: the programming determines the stop (full memory, number of readings reached). You can also read the data, which does not erase the current recording.

What to do if the display shows 'FULL' or 'Err'?

'FULL': the SD card is full. Remove it, free up space or use a new card, then recopy. 'Err': error writing to SD card. Remove the card, check its formatting (FAT32), and try again. In both cases, the red LED blinks and 'out' appears.

How to clean the device?

Use a damp cloth with a mild household cleaner or soapy water. Do not use solvents or aggressive products. Ensure no liquid enters the housing to avoid damaging the sensor.

How to mount the wall mount?

Place the wall mount at the desired location, mark the fixing points, prepare holes according to the material (screws and plugs not supplied), then fix the mount. Then slide the device into the mount, slide the security pin through the holes and lock with the supplied padlock.

Battery life

The programming windows of the software provide you with typical guide values for the expected lifetime of the battery. This lifetime is calculated on the basis of the following factors:

- Measuring cycle

• 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
