First steps6

Audible notification

The audible notification takes place with a signal tone whose interval frequency
increases with increasing gas concentrations. A continuous signal sounds when the
second alarm threshold is passed.

First steps

ã Charging battery:

Use only the original mains unit 0554 1093!

The rechargeable battery can only be charged at an ambient temperature
of 0 to 45°C ( 32 to 113°F).
If the rechargeable battery is completely discharged, charging takes approx. 8h.

In order to ensure as long a battery life as possible, the battery shoud always be
completely discharged and recharged.

The instrument can continue to be used during charging.

1

Plug the mains plug into the country-specific adapter and then plug into the mains

socket.

2

Plug the instrument plug into the mains unit socket of the instrument.

- Charging begins: , and light up alternately.

- Charging stops automatically when the rechargeable battery is full: lights up.

ã Using the earplug:

Use only the original earplug 0554 5001!

The instrument loudspeaker is deactivated when the earplug is plugged in!

Plug the connection plug of the earplug into the earplug socket of the instrument.

>

Using the product8

ã Carrying out gas detection:

Attention! Destruction of the sensor by non-desorbant substances (e.g. oils)!

> Do not use the instrument in dirty surroundings.

> Move the sensor head as close as possible, and slowly (3 to 5 cm per second)

over the parts which are to be examined for leaks.

Resetting maximum value display:

ã

> Press and simultaneously.

ã Switching instrument off:

> Press and hold until the display switches off.

Maintaining the product

Maintaining the product 9

â Charging the rechargeable battery:

See chapter “First steps”

â

Cleaning the sensor:

Tobacco smoke, dirty air, oils, grease, silicones and evaporating liquids or gases can
lead to deposits on the surface of the sensor. This can result in reduced sensitivity
and falsified display of concentrations. If necessary clean the sensor.

>

Switch on the instrument, wait until the end of the initialization phase and switch

off again. Repeat this procedure several times.

Clean the sensor head from the outside

â

> If dirty, clean the sensor head with a soft dry cloth.

â Cleaning the housing:

> If dirty, clean the housing with a damp cloth (soap solution). Do not use aggressive

cleaning products or solvents!

Switching on regularly

â

If the instrument is used infrequently, deposits may build up on the sensor.

Switching the instrument on prevents deposits building up on the sensor. Testo
recommends switching the instrument on regularly to avoid deposits building up
on the sensor.

â

Storage & transportation

To avoid contamination of the sensor, the instrument should not be stored

or transported in an environment where there is tobacco smoke, foul air, oils,
greases, silicones or evaporating liquids or gases. Any sensor that is contaminated
as a result of storage or transportation must be cleaned before use, see Cleaning
the sensor.

â

Regular servicing:

Testo recommends yearly servicing of the gas detector by an authorized service
centre.
