Detection.
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 its ability
to detect gas, however it will cause the battery indicator to read incorrectly.
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 by
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.
GasCheck Tesla instruments have the capability of displaying detected readings in a
variation of units; ppm, cc/s, mg/m
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 Centimeters 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
(milliliters per second). The GasCheck Tesla can typically detect Helium leaks down to
0.0005 of a cubic centimeter 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.
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
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.
