PC SPARK and BLAZE User Manual Communication between the dosimeter and a PC is made via an IR infrared interface module Not only does this provide a cable free way to connect to the computer but it also yields a very fast transfer rate of 115 000 bits per second The following Larson Davis IR interface modules are available for this purpose e DVX010 for USB port connections Introduction 1 15 FIGURE 1 15 DVX010 External IR Interface Module External IR interfaces connect to the computer s serial or USB port If you need assistance in installing or configuring the DVX010 see 706RC 705 703 IR Communications Troubleshooting on page D 1 The dosimeter can be used and stored in a wide range of temperature and non condensing humidity conditions However some precautions should be taken For example allow the dosimeter ample time to adjust to abrupt temperature changes Condensation may form inside a cold dosimeter if it is brought into a warm room or vehicle and may persist long after the outside case has adjusted to the ambient temperature Also temperatures inside closed vehicles can reach excessive levels Therefore do not leave the instrument in direct sunlight inside a vehicle A simple safeguard is to keep the instrument inside a sealed foam insulated case or bag with desiccant silica gel available at photographic equipment stores or from Larson Davis LD part number DSC001 1 16 Installing Batteries
