Instruction 19-9208 7
N
2
O Monitor 3010
Note: Only TWA values are displayed while in the auto-
stablization mode—normal ppm readings are not available.
While in the auto-stablization mode, and with a non-changing level of
N
2
O being dectected, the monitor automatically cycles the pump ON and
OFF for one minute intervals. Measurements taken during this time
allow the monitor to automatically correct the readings for any drift.
When a change in the N
2
O gas level is detected, the monitor interrupts
the cycle of turning the pump ON and OFF and keeps the pump ON.
Once the gas level stablizes, the process of cycling the pump ON and OFF
resumes.
Important! Do not attempt to turn the pump ON or OFF
while in the auto-stablization mode.
To exit the auto-stablization mode, remove the restrictor from the gas
outlet and switch the pump ON (or OFF and then ON if it is already ON).
The monitor will detect that the restrictor has been removed and revert
back to its normal mode of operation after a short time.
2.8 Leak Detection Mode
This mode is intended for the detection of leaks from pipes or equipment
containing N
2
O gas. While in the leak detection mode, the monitor emits
a beep with a repetition rate that is proportional to the concentration of
gas—the higher the gas level, the faster the beep. The monitor can thus
be used to detect gas leaks without the operator having to view the
display.
Activate the leak detection mode by pressing and holding down the f2
button until the following displays appear:
Momentarily pressing the f2 button will activate this mode, or turn it
OFF if already active.
