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.

5. Mounting

5.1 Mounting the wall holder

Mounting materials (e.g. screws, dowels) are not included.

1 Position the wall holder at the required location.
2 Using a pencil or similar, mark where the fixing screw is to go.
3 Prepare the area for mounting (e.g. drill a hole, put in dowel).
4 Mount the wall holder using a screw which fits.

5.2 Securing the data logger with a lock

1 Insert the data logger into the wall holder.
2 Place the retainer key in the wall holder.
3 Attach the lock to the wall holder (Accessory: Part no.

0554 1755).

12

5.3 Transportable unit

A unit can be made out of the wall holder, logger and the
interface to make transport or dispatch easier.

1 Push the data logger into the wall holder.
2 Push the interface onto the wall holder.
3 Secure the unit by connecting the wall holder and the interface

using the screw supplied.
