Disposal: In compliance with the European Union CE directive 2006/66/EC the battery in your De- fender should be removed for recycling prior to disposal of the Defender. The battery in the Defender is a valve regulated sealed lead acid battery. Please note that opening the Defender may damage connections so this procedure should only be used for battery dis- posal.
2.2 Activation Turning your Defender on and off Simply press the power button. • Press the On/Off button for 1 second to turn on your Defender. • When first turned on, your Defender displays an opening screen showing the product name, model number and flow range.
2.4 Display Screen Understanding the screen components The Defender 530 provides a menu of operational settings and commands. The four di- rectional arrow buttons on the control panel allow you to navigate through the menu and select the desired settings for your Defender. Your location within the menu is highlighted for easy identification.

Readings Choose the flow reading type to either volumetric ‘Vol’ or standardized ‘Std’. Volumetric flow is the actual flow at the ambient temperature and pressure whereas the standard- ized flow indicates a flow rate at a specific temperature and pressure. Standardizing pres- sure is set to a default value of 760 mmHg whereas standardizing temperature is an user settable value set at ‘Std To’...
Page 12
Units Measure gas Flow in cubic centimeters, milliliters, liters or cubic feet (all units are per minute). Measure Pressure in mmHg, kPa or PSI and Temperature in Celsius or Fahrenheit. Set the standardizing temperature by setting ‘Std To’ to a value from 0 to 50 deg C or 32 to122 deg F.
Preferences Read Default Select a preferred mode of measurement when the Defender is initially turned on. Default Settings Select <No> to allow the ‘Read Default’ change. Selecting <Yes> will reset your Defender to the factory default settings. (Factory default settings are provided elsewhere in this manual.) Data Port Set the data port interface by selecting:...

Diagnostics The Defender leak test is designed only to verify the internal integrity of the instrument and alert you to an internal leak. We recommend performing the Leak Test only as an intermediate quality control check or when- ever the integrity of the instrument is questioned due to misuse or accidental damage.

About This screen provides basic information about your Defender, which may be an especially helpful reference when speaking to a technical support representative or your distributor. Out of Range If the flow you are measuring is outside the Defender’s flow range, (see section 7 De- fender Specifications for ranges), the “Out of Range!”...
2.7 Measurements Taking gas flow readings To maintain the best possible accuracy and minimize thermal effects, Mesa recommends fully charging your battery before taking measurements. If this is not possible, we recom- mend disconnecting your Defender from its AC power adapter/charger while taking flow measurements —...
2.8 Single Measurement Each time the ‘Enter’ button is pressed, one measurement will be made. When each subsequent measurement is made, the current flow and average of all prior readings will be displayed. 2.9 Burst Measurement This setting functions in the same manner as ‘SINGLE’, but measurements continue automatically until the preset number of measurements has been made.
Page 18
Note: (010 in series) indicates the number of measurements. 10 is the factory-preset number. Define the number of measurement you prefer, from 1 to 100, by accessing the SETUP menu. In Continuous or Burst mode, select: • PAUSE to terminate the current flow measurement but to leave the average flow mea- surement and previous flow measurement on the screen.
3.1 DryCal Pro Software Visit Mesa’s website to download your copy of DryCal Pro software (http:// www.mesalabs.com/drycal-pro/) . DryCal Pro captures flow data from your Defender directly to a pre-configured table. The data can be exported to se- lectable Microsoft office environment.
4.0 Annual Maintenance and Calibration Assuring top performance and accuracy Your Defender is a precision measuring standard with moving parts machined to extremely close tolerances. Various environmental factors, product wear, drift of sensors, or inadvertent damage may adversely affect your Defender’s measurement accuracy or general performance. For these reasons, Mesa Labs highly recommends having your Defender annually verified by an ISO 17025–accredited laboratory, such as our Butler, NJ facil- ity, to ensure its measurement integrity.
