3.0 Operating Instructions
3.1 Getting Started
The IQM 60 is simple to operate:
•
Ensure that the 12VDC power supply to the IQM 60 is connected (rear panel).
•
Ensure the datacard is correctly inserted in the slot.
•
Turn on the power switch (front panel).
•
Remove the inlet cap and fit the supplied filter to the inlet
Note:
The IQM 60 should be allowed to run for 60 minutes so that it is fully warmed up before taking
readings.
3.2 Connecting a computer
The connection of a computer to the IQM 60, the installation of the software and its use are described in
Appendix A.
3.3 Reading the Datacard
Data is stored on the data card as a daily file. The format of the data is a tab delimited file which can be
opened with standard graphical software such as MS Excel. Always turn off the IQM 60 before removing or
inserting the data card. To remove the data card gently press inwards and then let go to release the latch.
3.4 Testing
Zero and span checks should be performed with humidified air (detailed description provided in section 5).
Aeroqual supplies a Nafion gas humidifier. If the IQM is to be deployed in environments with low or high
absolute humidity it is recommended that the sensors be zero and span calibrated under those conditions,
since the sensors are slightly sensitive to changes in absolute humidity.
3.5 Maintenance
The IQM is designed to operate without maintenance for extended periods. The following table outlines a
periodic maintenance schedule for the IQM. This schedule is based on experience under normal operating
conditions and may need to be modified to suit specific operating conditions.

3.6 Care and Cleaning
Keep the IQM dry. Avoid water and/or condensation as humidity and liquids containing minerals may
corrode electronic circuits.
Do not use or store in dusty, dirty areas.
Do not store or turn off the monitor in temperatures below 5°C.
This unit is designed for use at temperatures between 5°C and +45°C. If you wish to use the monitor
outside this range you will need an additional environmental enclosure. Sudden changes in
temperature will cause condensation that may damage the electronic components.
Do not drop, knock or shake as this could lead to internal damage.
