The primary operational use of the MobileTrace® is to obtain samples to detect traces of narcotics or explosives. The device is intended to be used with little to no operator supervision. It is equally important to adopt procedures to ensure the integrity and accuracy of results obtained from the device. The screenshots shown are for instructional purposes only and may not represent your specific configuration settings. Sampling Matrix In situations when a particle sample cannot be obtained, vapor analysis with the MobileTrace® detector can be performed in universal mode. Vapor sampling is not designed for sampling open areas. It is intended for use in sampling confined areas such as trunks of vehicles, glove compartments, lockers, bags, cases, etc. Contraband stored for some time in a confined area (especially at elevated temperatures) has the best chance for successful vapor detection. Some substances have a higher probability of being detected in vapor mode. See (see Table 5- 1). The vapor method should be selected to allow lower alarm levels and manual control of the sampling pump. The operator should locate a vapor release point on the suspect item and, while ensuring not to make physical contact, hold the device’s desorber close to this point. The operator should then press and hold for 8-10 seconds (to draw in vapors that are escaping through the vapor release point of the suspect item) either the Trig button on the Main screen, the green button on the navigation pad, or the green button on the device handle. Once the trigger button is pressed a second time, the device completes the analysis and indicates whether or not a substance has been detected.

7. Press the power button on the rear of the device to turn the device ON, and allow it to warm up. Calibrate the Battery If the battery is in need of fuel gauge recalibration, the red LED on the charger will flash upon insertion of the battery. This indicator provides feedback to the user on the accuracy of the fuel gauge and avoids unnecessary battery calibration cycles. The user has the option to calibrate the fuel gauge and charge the battery, or to only charge the battery. This option is given because a recalibration cycle is longer than a charge cycle and it may not be convenient to go through the calibration cycle. To recalibrate the battery, press the Calibrate button on the front of the charger. No action is required if only a recharge is required, as the charger will automatically begin to charge the battery. The blue calibration LED will flash to indicate that the battery is undergoing the recalibration cycle. There may be a short delay before the calibration begins. During calibration the discharge resistors will heat up and the fan will operate to maintain temperature within acceptable limits. Removing the battery and/or pressing the calibration button again will restart the process from the beginning. At the end of this procedure the blue LED will stay constant indicating a fully charged, fully calibrated battery. The most common cause of calibration failure is overheating of the pack during discharge. Keep the charger away from direct sunlight or heat sources. Battery Notes What is recalibration and why is it needed? The fuel gauge in the battery uses a highly accurate voltmeter, ammeter, and time clock to measure actual charge in and out of the battery pack. In addition, there are algorithms to compensate for the effects of discharge rate, discharge temperature, self-discharge and charging efficiency, and so on. Recalibration is the means to ensure the continued reliability of this device throughout the life of the battery pack. Recalibration is used to reset the fuel gauge algorithms, reestablish the full and empty points, and recalculate the actual capacity in the battery. In this way, even as the battery ages and things change, the accuracy and reliability of the fuel gauge can be retained throughout the life of the battery. The charger will automatically take the batteries through this process and is a useful alternative, ensuring accuracy and reliability of the fuel gauge throughout the life of the battery. Recalibration consists of a calibration charge, followed by a calibration discharge. Finally the battery is given a regular charge. A calibration cycle will be faster if the battery is fully charged to begin with. Recalibration time for the device main battery could be up to 14 hours.
