Charging Charging Charging Charging Charging Place the EX-TEC® SNOOPER H (switched off) in the charging adapter. They are connected via the charging contacts (item 7) and the adapter contacts (item 2 in the illustration on page 14). An acoustic signal sounds to indicate the start of charging. The charging period required is calculated from the operating hours and a display of the following type appears: l the detector has 5 operating hours left (=...
DVGW work sheet G 465/IV specifies that servicing and maintenance of the detectors may be carried out only by the following persons: the SEWERIN Service Department or an expert authorised by SEWERIN. Servicing must be carried out at least once a year. The next scheduled date must be entered on the inspection sticker attached to the detector (month/year).

Adjustment The EX-TEC® SNOOPER H is factory-set with test gas. You can adjust the detector using an appropriate test gas. To carry out the adjustment you need: the EX-TEC® SNOOPER H, charged the SPE test set the SNOOPER H or SNOOPER H small test head 1.00 vol.% methane or propane test gas in synthetic air the adjusting pin Carry out the process exactly the same way as function-testing...

Changing the sensor system There are different probe models for the EX-TEC® SNOOPER H for various points in the pipework system: manual probe with spiral cable flexible swan-neck (245 mm long) rigid probe extension (525 mm long) flexible mini swan-neck with sensor (145 mm long) The probes can be exchanged or extended in any required combination.
Technical notes Sensor lifetime The lifetime of the sensor may be shortened by the following undesirable influences: The sensors are deleteriously affected by gaseous components of silicones, oils and phosphate esters, which irreversibly re- duce their sensitivity. Pollution of the measuring environment by halogens, burnt neo- prene, PVC, trichloroethylene and the like also weakens the sensitivity of the sensors, but in this case it can be regenerated.
