Functions
Battery selection
The GasCheck Tesla will operate using AA size
batteries in either Alkaline (non rechargeable) or
Nickel Metal Hydride (Rechargeable).
Select the battery type using the 'Up or Down'
key and then press the 'Esc' key to exit to the
Main menu.
Failing to select the correct battery type will not damage the instrument or affect it's
ability to detect gas, however it will cause the battery indicator to read incorrectly.
View Data
The GasCheck Tesla instrument has the ability to data log 10
readings within its internal memory. To store a reading press the
'ENTER' key while on the main Running screen. When readings
are stored in memory a symbol will appear on the Main viewing
screen.
When the memory is full the 'Data' symbol will flash. The stored data can be viewed
buy scrolling through the logged readings using the 'Up and Down' keys. To delete
the stored data press and hold the 'ENTER' key, the 'Trash can' symbol will flash,
continue holding the 'ENTER' key until the data is deleted. Press the 'Esc' key to exit
to the Main menu.
Units
GasCheck Tesla instruments have the capability of displaying detected readings in a
variation of units; ppm, cc/s, mg/m
3
and g/yr.
Use the 'Up and Down' keys to select the desired unit and then press the 'Esc' key
to exit to the main menu.
Please note: the Custom Calibration routine automatically selects the type a
calibration depending on this setting. See the ‘Calibration’ section of this manual.
cc/sec = Cubic Centimetres per second offers a volumetric leak rate that directly
measures the volume of a gas escaping from a given point, it is also known as
ml/sec (Millilitres per second). The GasCheck Tesla can typically detect Helium
leaks down to 0.0005 of a cubic centimetre per second.
ppm
= Parts per million, this unit indicates a concentration but can't be used to
quantify a volume of gas leakage.
mg/m
3
= Milligrams per meter cubed, like ppm this unit is also concentration so can't
be used to quantify a volume of gas leakage.
g/yr
= Grams per year offers an alternative volumetric leak rate that directly
measures the volume of a gas escaping from a given point.
Display
GasCheck Tesla instruments have the capability of displaying cc/sec and g/yr
readings in either decimal or exponent form. (Readings in ppm and mg/m
3
can only
be displayed in decimal form.)
Use the 'Up and Down' keys to select the desired unit. Press the 'Enter' key to
display the next screen. Use the 'Up and Down' keys to select the desired display
and then press the 'Esc' key twice to exit to the main menu.
