8. he MicroCure s sample rate of 2000 samples per second produces accurate readings at high system speeds Ideally a MicroCure is jogged through a web process to make its application and removal from the process easier Since dosage readings are directly proportional to exposure time a reading for a high speed system can be derived from a reading taken at a slower speed For example if the system speed is usually 600 feet per minute jog the system down to 60 fpm and take a dosage reading This reading represents the UV dosage of the system at 1 10th the speed To translate this to 600 fpm simply divide the dosage reading by 10 NOTE Irradiance readings with the MicroCure Plus should be consistent and are not dependent on speed The MicroCure Plus should register similar irradiance readings when consistent data collection techniques are followed Maintenance MicroCure Radiometer Clean the radiometer s aperture with a cotton swab and isopropyl alcohol Use isopropyl alcohol and a soft cloth to clean the case of the radiometer Do not open the radiometer s case There are no user serviceable parts inside the unit The MicroCure radiometer is given a one time calibration before it is shipped from EIT It is specified to take 200 readings or last for one year Once the unit meets one of these conditions it must be replaced DataReader The only maintenance required for the DataReader is occasional battery replacement The DataReader will indi
