Running screen
GasCheck Tesla displays the 'Running screen' whenever the instrument is being used to detect leaking gas, the
illustration below outlines the various information and icons.
Gas selection
The GasCheck Tesla displays the gas being measured in the top left of the running screen. The GasCheck Tesla will display
the gas as selected at the factory, however the Tesla has a range of gases that can be selected via an internal gas table.
Sensitivity
GasCheck Tesla has three (3) sensitivity levels, X100 (times one hundred) is most sensitive, X10 (times ten) is mid-range
and X1 (times one) is least sensitive. See the sensitivity of various gases on the table under ‘Functions (continues), Gas
Selection’.
Battery status
When the battery symbol is filled in the battery is full, when just an outline is displayed the battery is exhausted.
Backlight
The backlight symbol shows the status of the backlight even in bright daylight.
Gas measurement
The GasCheck Tesla measures the leak rate of gas leakage in which ever units are selected.
Sound indication
This symbol shows if the sounder is on or off, if the semi-circle (on the right) of the symbol is present then the sound is
switched on, if not the sounder is switched off. The beep that occurs with each key press cannot be switched off.
Bar graph
The bar graph increases as gas is detected. This graph is not scaled and should be used for indication only.
When gas is detected and the bar graph has reached its maximum level, a different sensitivity level can be selected to
give a wider detection range.
Peak hold
When selected, peak hold displays the maximum measurement on the display. Pressing the ENTER key resets the
reading but also logs the peak reading in memory.
