2. About Your Monitor
The Aeroqual
Series 300, 305, 500 and 505
Monitors
have been spe-
cifically designed to incorporate Aeroqual‟s in-depth knowledge of accu-
rate ambient gas measurement. Different sensor heads are used for
specific gases or depending upon whether high or low concentrations
are to be measured. All the sensor heads are interchangeable on the
same base unit.
The following information details the operation and features of the moni-
tors:
1. The monitors are modular in design and are comprised of
two
main components
, a Series 300, 305, 500 or 505 monitor, and a
sensor head. This affords the user the ability to replace faulty sen-
sor heads without having to replace the monitor. The monitors can
be mains and/or battery powered and either permanently mounted
or used as portable units.
2. The sensor head is calibrated prior to delivery and does
not nor-
mally need to be re-calibrated
during its life. (Specific user
guides are supplied for the special operations of particular sensor
heads).
3. The Aeroqual
Series 300, 305, 500 and 505 Monitors
come with
on-board diagnostics, which will inform the user if the sensor is
not operating correctly.
4.
High and low alarms
. The high alarm is indicated by flashing
arrows pointing upwards accompanied by a fast beeping sound.
Similarly the low alarm is indicated by flashing arrows pointing
downwards accompanied by a slow beeping sound. This sets
both the monitor and external alarms.
5.
Alarm mute.
Two alarm mute functions are available, temporary
and permanent mute. Temporary mute is only active during the
specific alarm condition, while permanent mute will remain on until
reset by the user. The alarm arrow indications remain active dur-
ing both temporary and permanent mute.
6.
Control.
This enables external equipment to be controlled by the
monitor using the high and low control settings, which can be
used to control an external device.
7.
Concentration unit selection.
The concentration can be dis-
played in either ppm or mg/m3.
8.
Min / max / average measurement cycle.
The monitor will dis-
play the minimum, maximum, average and 15-minute average
gas concentrations over the measurement period. The Series 305
& 505 will also show temperature and relative humidity in addition
to gas concentration.
9.
0-5V Analogue signal.
A proportional voltage output is available
from the external output. The voltage relates to the gas concen-
tration, with 0 V representing 0 concentration and 5 V represent-
