Page 12: Acoustic Alarm
Acoustic alarm The acoustic alarm is the buzzer below the F2 function key. This sounds for im- portant events or error messages. Optical alarm An optical alarm is indicated by several bright alarm LEDs above the display. The LEDs flash at the same frequency as the acoustic signal sounds. Bluetooth (integrated) The integrated Bluetooth module is used for standard data transfer and for up- dating the device firmware. -
Page 13: Nameplate
Nameplate The nameplate with the device name, article number (PN) and serial number (SN) is on the back of the device. Storage, transport, packaging After unpacking, during transport and before and after storage, check the device for visible damage. If there is any damage, please contact your sales partner. Power supply (charging) To be able to use the device at any time, check the charge level of the Li-ion battery. -
Page 14: Operation/Handling
Operation/handling Switching the device on and off Switching on the device 1. Press ON/OFF (OK/ENTER) for at least 2 sec- onds. 2. Wait for the system and pump test. 3. Confirm the service date with CONTINUE (if displayed). Result: The device displays the main menu. Switching off the device The device can only be switched off from the main menu. -
Page 15: Selecting The 'Info' Menu And Checking The Values
Selecting the 'Info' menu and checking the values The 'Info' menu displays the serial number (SN), software version, free memory, date, time, and bat- tery charge level. Confirming the service date The service date is displayed when the device is started to inform the user. -
Page 16: Changing The Filter
Changing the filter Filters are designed to protect the measuring device from serious dam- age. Moist or dirty filters reduce the flow rate and extend the response time of the measuring device. The proper function of the device can only be guaranteed when the filters are dry and clean. - Page 17 Filter assembly: ① No. Description ② Dust filter ③ Hydrophobic membrane 1 (do not touch!) ④ Filter housing Hydrophobic membrane 2 (do not touch!) Replacing the dust filter The dust filter should be changed much more frequently than the entire filter housing (depending on the conditions of use, in a ratio of 10:1).
-
Page 18: Replacing Filters In The Water Blocker
Replacing the complete filter housing The hydrophobic filter/hydrophobic membrane must not be touched with bare fingers, as this will damage it! Preliminary work • Clean the device and screw cap (so that it is free from dust and moisture) • Make sure that tweezers are at hand Replacing 1. -
Page 19: Cable Fault Detection
Cable fault detection With cable fault detection, you can detect the smallest gas concentrations of burnt insulation material above or in the ground. Probes are connected to the device for detection. The gases are directed to the sensors via the integrated pump in the device. -
Page 20: Examples For The Use Of The Probes
In addition to the two probes supplied, gases can also be directed to the sen- sors via the optional VSS 15 vacuum probe system. Detailed information on the use of the vacuum probe system can be found in the relevant operating instructions. Examples for the use of the probes The figures illustrate the differences in measurement results due to the use of the probes under different conditions. - Page 21 All the illustrations show an example of the gas quantity and gas distribution, a display and a trend arrow of the measured ppm value. With the bell probe ①, you can measure gases oc- curring directly on the ground. The smallest amounts of gas on the ground are also an indication that high concentrations can be found below the surface.
-
Page 22: Display Of Gas Concentrations
Display of gas concentrations Two different displays of the gas concentration are integrated in the device. • The gas concentration of burnt insulation material • The gas concentration of natural gas or a gas similar to natural gas If the device displays the gas alarm, you should pass this information on to the competent authorities known to you. -
Page 23: Resetting The Maximum Value
Resetting the maximum value Method (which display will Procedure reset?) Manual If no more gas is measured, you can reset the maximum value with F1 after a short time. (Number and line) Alarms In certain situations, an alarm is sounded via the device's signal generator. The alarms with the associated message on the display are: When is the alarm triggered?

Page 24: Performing Tests
Performing tests For longer periods of work, wear the Fault Sniffer 2 together with the waist belt to protect your back. This is the only way to distribute the weight of the device over a large area in a way that is gentle on your back. -
Page 25: Calibration/Adjustment
If the calibration/adjustment fails after several attempts, please contact the manufacturer. Sensors may have been damaged due to prolonged contact with very high gas concentrations or other influences. Test gases that may be used Only use the test gas recommended and distributed by Megger. -
Page 26: Performing The Calibration
Performing the calibration You can perform the calibration in a menu-guided way. Observe the operating instructions shown on the display. You can press BACK/ESC to cancel the calibration at any time. Requirements • Test gas is available, but is not yet connected to the device. •... -
Page 27: Performing The Adjustment
Performing the adjustment You can perform the adjustment in a menu-guided way. You must perform the calibration before and af- ter the adjustment. This is because you can only per- form the adjustment by means of a previous calibra- tion. And you use the subsequent calibration to check the newly adjusted sensors. -
