RTC

RTC stands for "Real-Time Clock". This is for adjusting the time and date settings.

USB Mode

"USB Disk" setting is selected by default. In this mode the SniffIT X1® acts as a mass storage device
when connected to a computer. This way the user manual is accessible as it were stored on an
internal USB memory.
"USB VCP" setting is an unavailable feature.

Auto off time

Using the integrated accelerometer after the set time (minutes) the SniffIT X1® will shut itself down
to save battery. Setting this value to "0" disables the function.

HLrange

The SniffIT X1® unit has two different sensitivity ranges. One is called the High sensitivity range,
suitable to detect low leak rates, the other is the Low sensitivity range, suitable to detect high leak
rates.
Basic operation of the unit is as follows. The unit is turned on. It is recommended to wait 10 minutes
before starting the measurements so the unit can adapt to the ambient conditions. Go to
Measurement mode and select High sensitivity. Navigate the sniffer probe close to the tested object
and move it along the objects surface. If a leakage is detected, the visible information is displayed on
the bar graph and a Leak rate/time graph. If the leak rate is higher than the upper limit of the high
sensitivity range then the edge of the display turns blinking red, audio and vibrating feedback alarms
turn on (if enabled). At this event the operator should switch to the low sensitivity mode to be able
to pinpoint the leak location precisely.
The high and low sensitivity ranges are defined as windows over the complete measurement range of
the unit. The detectable range spans from 1,0E-05 to 5,0E-02 mbar∙l/s. In the menu point
"Settings/HLrange" the operator can define two windows over this range. High Min and High Max
defines the bottom and top of the high sensitivity window respectively. Low Min and Low Max
defines the bottom and top of the low sensitivity window respectively. The two windows cannot
overlap, which means Low Min can never be a lower value than High Max.
1. Choose the submenu "HLrange".
2. Choose "High_Min". Enter the desired minimum value, for example 1∙10
Screen menu button until 1.00e-05 is shown on the display. Press and hold the Screen menu
button to store value and leave the submenu.
Choose "High_Max". Enter the desired maximum value, for example 5∙10
Screen menu button until 5.00e-05 is shown on the display. Press and hold the Screen menu
button to store value and leave the submenu.
