Page 9: Installation
When monitoring for the potential presence of multiple toxic gas types, the unit should be calibrated for the least cross-sensitive toxic gas. NOTE: These guidelines are ONLY intended as a general directive for the placement of the GASMAX MX. This information should NOT serve as a complete list when considering all potential parameters for the proper location of the unit. - Page 10 MOUNTING THE ENCLOSURE It is recommended to mount the GASMAX MX to a solid structure (such as a concrete wall, steel column, or angle iron) where a minimum of vibration will be transmitted to the unit. Alternately, a pole may be used along with a strap or a U-bolt, if it is rigid and of sufficient strength.

During normal operation, the display shows the current measured and calibrated gas value, the gas engineering units (“ppm” or “%LEL”) and the type of sensor attached. During normal operating mode, the GASMAX MX continuously samples the air and updates the measured concentration of the target gas on the display screen. - Page 13 GASMAX MX User’s Manual, Revision 1.0 Powering off the device stops the operation of the unit. The product settings and configuration, as well as the operation settings, including the null and calibration of the sensor, will be unaffected.

Page 16: Calibration
Calibration is the process of evaluating and adjusting the precision and accuracy of measurement equipment. Although GDS Corp tests and calibrates every device at the factory, for best accuracy, the GASMAX MX SHOULD be initially calibrated in the environment where it is installed. - Page 17 GASMAX MX User’s Manual, Revision 1.0 3. The unit will automatically begin the 12-second null process. During null, the display will show a countdown of the time remaining until the process is complete. When the null process is complete, press the MENU button to advance to the next screen.
- Page 18 Press the MENU button to continue. Press the MENU button to start the automatic calibration process. 11. The GASMAX MX will automatically begin the 120- second calibration process. During calibration, the display will show a countdown of the time remaining until the process is complete.

Page 19: Maintenance
SENSOR REPLACEMENT The sensor elements used in the GASMAX MX detects gas in either % or PPM concentrations; this element must be fully functional for the system to operate correctly. GDS Corp recommends replacing the sensing element whenever a slow response to gas is observed during the normal calibration process. - Page 20 Press the ADD button to power-up the GASMAX MX BATTERY REPLACEMENT The GASMAX MX battery life will vary based on the sensor type and the presence of gas that will increase the radio transmission rate (and decrease this battery life) It is recommended that the batteries be replaced when the voltage reported is 3.2 volts or less.
