Battery Replacement; Electromagnetic Compatibility; Sensor Filter And Sensor Replacement - Rothenberger ROTEST Electronic 3 Instructions D'utilisation

 The 'Tip-light' is used to see around the area of the leak when in a dark environment.
 When this instrument is used in noisy environments, look at the red LED which flashes more
rapidly as the tic rate increases. The optional earphone can be plugged into the unit's side if
there is high background noise or the operator does not want to disturb other people. This
also disables the speaker.
 If the tic rate becomes uncontrollable, it may be necessary to change the sensor.
 The detector will respond to some leak finding solution (e.g. Soap), so please use your
detector first. If over exposed to some gases, the detector may take an extended period of
time to return to normal.

Battery Replacement

 Remove the battery case cover.
 Replace the 9V alkaline battery. An alkaline battery should always be used. Ensure the
polarity of the battery matches that shown in the compartment.
 Replace battery case cover.

Electromagnetic compatibility

The European Council Directive 89/336/EEC requires that electronic equipment does not generate
electromagnetic disturbances that exceed defined levels and has an adequate level of immunity
to enable it to be operated as intended. The specific standards applicable to this product are
detailed in the appendices.
Since there are many electrical products in use that pre-date this Directive and may emit
electromagnetic radiation in excess of the standards defined in the Directive there may be
occasions where it would be appropriate to check the analyser prior to use. The following
procedure should be adopted:

Go through the normal start up sequence in the location where the equipment is to be used.

Switch on all localised electrical equipment that might be capable of causing interference.

Check that all performance are as expected. (A level of disturbance in the performance is
acceptable). If not adjust the position of the instrument to minimise interference or switch
off, if possible, the offending equipment for the duration of the test.
At the time of writing this manual (December 2002) there is no awareness of any field based
situation where such interference has ever occurred and this advice is only given to satisfy the
requirements of the Directive.

Sensor Filter and Sensor Replacement

The sensor is housed at the tip of the gooseneck assembly.
To remove the sensor:
 Turn the unit off.
 Pull off the top half of the sensor housing. Pushing to one side aids removal.
 With care move the 'Tip-light' LED to one side to gain access to the sensor (small silver can).
 Unplug the sensor and replace it with a new one.
Note: The sensor can be fitted in either one of two ways without affecting instrument operation.
 Realign the LED ensuring it sits above the sensor
 Replace sensor cover by pushing it firmly in place. Note! The locating pin between the body
and sensor cap.
