1. Basic safety instructions

Please read through the following safety instructions carefully:

Avoiding electricity:

Never use the instrument and external probes to measure on or near live parts if the instrument is not expressly approved for current and voltage measurement!

Product safety:

Prior to each measurement, check if the connections are connected properly via the blind plug and if the right probe is correctly inserted. Otherwise the protection class specified in the Technical data cannot be guaranteed.

The logger should only be operated within the parameters specified in the Technical data.

Please handle the logger with care.

The instrument should only be opened if expressly described in the instruction manual for maintenance purposes.

Force should never be applied!

Only for testo 177-4

The probe sockets in testo 177-4 are not isolated from one another. Please take note of this when using surface probes with a non-insulate thermocouple.

Disposal:

Please dispose of spent batteries responsibly.

You can return your logger directly to us at the end of its service life. We will dispose of it responsibly.

2. Intended use

The testo 177 data loggers are used to save and read out separate readings and measurement sequences. The readings are measured, saved and transmitted to a PC, to the testo 575 fast printer or to the testo 580 data collector per infrared using testo ComSoft software.

The data logger with the above factory defaults can be used immediately.

If you wish to use other measurement criteria, you will have to program your data logger in accordance with your requirements using testo ComSoft software (See 7. Programming, P. 14).

External probes can be attached to many of the data loggers (See

6. Connecting probes, S. 13).

*Reading information:

Max = highest reading, Min = lowest reading, Act = Intermediate reading (is shown in display but is not saved), Log = saved reading

Status information:

Wait = Waiting for program to start, Rec = Measuring program is running, End = Measuring program is finished

Due to technical reasons, the display speed of the liquid crystals slows down at temperatures below 0 °C

(approx. 2 s at -10 °C, approx. 6 s at -20 °C). However, this does not have any influence on the accuracy of the measurement.

3The battery symbol is updated when:

-the wraparound memory is full

-measurement program is started/ended

-In Record mode: Once a day

-the GO button is pressed:

if last measurement was more than 24 hours ago

Alarm led

(red LED)

Status led (green LED)

The LED functions can be switched on/off via testo ComSoft software.

In all modes:

The Alarm led flashes three times every 15 seconds if the remaining battery capacity is less than10% (even if Alarm led is deactivated).

Wait mode and Key start start criterion programmed:

The status led flashes five times if the GO button is kept pressed for approx. 3 s (even if the Status led is deactivated).

It is confirmation that the measuring program was started and that the data logger is now in the Record mode.

Record mode:

The Alarm led flashes once every 15 s if alarm values have been exceeded (only if Alarm led is activated).

The Status led flashes once every 15 s (only if the Status led is activated).

It is confirmation that the measuring program is running.

The Status led flashes five times if the GO button is kept pressed for approx. 3 s (even if Status led is deactivated).

It is confirmation that a time mark has been set.

4.Display and control elements

4.3Display sequence

Depending on the mode, different information can be displayed in the data loggers with display. You will find a detailed description of the information which can be called up in the short version of the instruction manual enclosed with every data logger.

4.4 Button functions

In all modes in data loggers with display:

Press the button to switch between the displays.

Press the GO button to activate an intermediate measurement.

Wait mode and Key start start criterion programmed:

Press the GO button for approx. 3 s to start the measuring program.

-The measuring program starts, Record appears in the display (if available) and the Status led flashes five times.

Record mode:

Press the GO button for approx. 3 s to set a time mark.

- The Status led flashes five times.

Time mark: This function enables you to monitor and read out/print out the memory content from a specified point in time (time mark) without having to reprogram the data logger. The readings from Start (All readings) are also saved.

The readings from Start (All readings) or From time mark can be read out on the testo 575 fast printer or the testo ComSoft software.

The readings from Start (All readings) can be read out on the testo 580 data collector.

Only one time mark can be set. If the GO button is pressed for approx. 3 seconds in the Record mode, the existing time mark is deleted and a new time mark is set up.

-The readings (max./min. values, exceeding of alarm values) are shown in the display (if available) from the set time mark.

5. Mounting
