Function
The sound switches the audible indication of the leak rate on and
off. The frequency of the signal increases as detected gas levels
increase. Use the up or down key to move the tick to the desired
position and then press the esc key to return to the main menu.
Note: An audible beep can also be heard whenever the keypad is
pressed, this beep cannot be switched off.
Peak hold can be used to record the highest detected reading on
the display until the enter key is pressed. Use the up or down key
to move the tick to the desired position and then press the esc key
to return to the main menu. When you use the Phoenix Mobilis in
peak hold mode, press the enter key to clear the held reading. The
reading held on the screen will be logged when the enter key is
pressed.
Calibration can be used to switch between the factory calibration
setting and user defined calibration parameters. Factory calibration
cannot be adjusted. User defined calibration is described in
Calibration
on page 21.
Battery selection can be used to select whether the batteries
installed are Alkaline (non-rechargable) or Nickel Metal Hydride
(rechargeable). Select the battery type using the up or down key to
move the tick to the desired position and then press the esc key to
return to the main menu.
Note: If you do not select the correct battery type, it will not
damage the instrument or affect its ability to detect gas, however it
will cause the battery indicator to read incorrectly.
View data allows 10 readings to be logged in internal memory and
recalled later. 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 running screen. When the memory
is full the 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 symbol
will flash, continue holding the enter key until the data is deleted.
Press the esc key to exit to the main menu.
Units selects the leak rate units displayed on the LCD screen.
Select the required units using the up or down to move the tick to
the desired position and then press the esc key to return to the
main menu. The following units are available:
cc/sec = Cubic Centimetres per second (volumetric leak rate)
ppm = Parts per million, (concentration)
mg/m
3
= Milligrams per metre cubed (concentration)
g/yr = Grams per year (an alternative volumetric leak rate)
The display allows the cc/sec and g/yr units to be displayed in
decimal or exponential format. Select the required format with the
up or down key to move the tick to the desired position and then
press the enter key to return to the main menu.
Note: Readings in ppm and mg/m
3
can only be displayed in
decimal form.)
