Page 3 4.0 SYSTEM PROPERTIES: Introduction: GAS-CHECK SF6 is a portable, mains-independent instrument for leak detection and leak measurement of SF6 gas. Although designed for SF6, other gases with a high affinity for electrons, such as refrigerant R12 may also be detected.

Page 5 6.0 HANDGUN BUTTONS: S QUARE : This has two functions: MEASURE MODE and SEARCH (bar graph) MODE. On power-up the SEARCH mode is automatically selected, the touch screen displays a bar graph. This is ideal for fast and ultra low-level leak detection (~10 E-8cc/sec).
Page 6 7.0 GETTING STARTED: This assumes you have just received the instrument and it is NOT powered up. 1 Plug in the sensor and connect the ha ndgun to the console. Align the red marks and press home. 2 Connect to a mains electrical supply AC 85-265V.
Page 7 7.3 LOW FLOW ERROR: The flow through the sensor is controlled by the vacuum pump. The level of vacuum required to maintain the required flow can be seen in the lower LH screen. Should the sample intake of the sensor be partially or totally blocked, the instrument will first try to compensate by increasing the vacuum.
Page 8 8.1 USER SETUP : This paragraph describes the parameters that determine the behaviour of the instrument. The first step is always. Activating the Menu System. In normal operation, the instrument can be taken to programming mode by simply touching the touch-screen.
Page 9 9.2 D ata Printout If readings were stored using the STORE key on the hand unit, these can be printed or transferred to a computer. After printout, the data memory is cleared. See section 16.5 page 15 for ISL supplied printer settings and information.
Page 10 10.2 F orce Operator ID by key code If selected, a password (key code number) entry screen is opened after power up. The operator is now required to enter his personal key code. If nothing or an invalid key code is entered, data printout is not possible.
Page 11 11.0 C alibration The GAS CHECK SF6 is unique in that completely separate values are stored for each of the display modes. This means that if you want to measure ppm or gm/yr these values must be calibrated before use. Calibration follows the same easy routine as with cc/sec calibration using the Portable Reference Leak .
Page 12 12.0 U ser set-up This gives access to a number of parameters which determine the behaviour of the instrument. They are described as follows and all are selected using the up/down arrows and changed using the -/+ buttons. 12.1 Peakhold (gauge).
Page 13 13.0 Desens Factor 1. Factory pre-set at x5. On a high or ‘gross’ leak, press the GREEN handgun pad once. This desensitises by x5; the Green (special) lamp will flash. 13.1 Desens Factor 2. Factory pre-set at x5. Pressing the GREEN handgun pad again invokes a further desensitise, the lamp will flash faster.
Page 14 14.2 Sound type Using the +/- buttons select sound output you prefer. HARMONIC or TRADDITIONAL. If more than one instrument is used in a confined space, it may be useful to set them to different sound types. 14.3 Sound begins at This allows you to set the display value at which the sound begins.
Page 15 15.1 Probe/Sensor Li fetime/filter: Sensor life is presently estimated to be 200 hours of continuous use in a normal industrial atmosphere. Sensor life is affected only by contamination in the air sample being drawn through probe. Therefore it is dependent on ambient conditions.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il ion science SF6 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del ion science SF6 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso ion science SF6 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul ion science SF6 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il ion science SF6, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del ion science SF6.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il ion science SF6. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo ion science SF6 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
