O Monitor 3010
1.0 INTRODUCTION
1.1 General
The Bacharach N
2
O Monitor 3010 is easy to use, but it is essential that
this instruction manual be read and understood by all operators and
maintenance personnel prior to using or servicing the monitor.
The 3010 is a compact and lightweight N
2
O monitor that displays the
current level of N
2
O gas in either the range of 0 to 1,000 ppm, or a Time
Weighted Average (TWA) ppm value.
The monitor is based on the infrared-absorption principle using a low
volume, dual wavelength infrared cell to detect the presence of N
2
O. The
3010 draws in a gas sample using its internal pump, which can be turned
ON/OFF by pressing the f
3
button. The monitor automatically stores gas
readings in memory at predetermined intervals. The stored data can be
later downloaded to a personal computer via its integral IrDA communi-
cations link and optional BACH-COM software.
The monitor can be operated in the following three modes: 1) normal
(real-time) ppm readings, 2) auto-stabilization for increased stability
during long term TWA measurements, and 3) leak detection.
