Wireless Operation System UV Energy Meter

Introduction
The EIT Instrument Markets MicroCure ® is a radiometer that addresses UV measurement and process control in areas where radiometer placement is difficult. The MicroCure ® combines its compact size and adaptability to address a variety of demanding physical and thermal environments. These attributes make it possible to obtain measurements in curing applications that were previously inaccessible to radiometers.
The MicroCure ® radiometer is a microprocessor-based, calibrated, electro- optic instrument that measures and accumulates total UV energy and UV irradiance applied to its measurement surface. The DataReader reads and displays the data collected by the MicroCure ® radiometer.

Establishing a Cure or Process Window
A cure or process window is a set of parameters that defines equipment settings and run conditions to ensure proper curing. A cure window gives the user assistance in troubleshooting deficiencies in a UV process. Ideally, tests are run for every combination of coating and substrate so that a history can be obtained. This history helps establish baseline parameters for various chemical and material combinations and provides important information for process control. The operator can compare a current measurement to the cure window and adjust the process to get the desired curing results.
The process value is often defined as total energy or total energy produced by a system. It is the mathematical integration of lamp intensity over time. The MicroCure ® derives this value by measuring instantaneous lamp irradiance during the run and then summing them together. The process value must be maintained to get complete UV curing every time.

Handling and Safety Precautions
Due to the radiometer's data transfer, case configuration, and the applications for which it was designed, the following precautions should be observed to ensure the radiometer's performance.
• Avoid conductive materials, including process chemicals, process vapors, and anti-static mists when handling the MicroCure ® . These materials may cause the unit to short, reset and lose stored data.
• Handling the MicroCure ® with gloves reduces the chances of a short occurring.
• Do not let the MicroCure ® radiometers travel through print stations, die cutters, pinch rollers or other processes which may damage both the radiometers and your equipment.
• Do not short the two case sides of a MicroCure ® together. Doing so will reset the unit and any stored data will be lost.
• Do not allow MicroCure ® radiometers to touch each other. Data loss or corruption may occur.
• Do not mark or label the MicroCure ® radiometer case.

Operation
1. Insert the MicroCure ® into the slot in the upper left side of the DataReader.
2. Press the RESET button to move the unit from standby/sleep mode to turn the unit on to active data collection mode. The DataReader will briefly display the software version (Px.xx), "rxx" where "xx" is the number of unit resets, then "0.00" to indicate that the unit is ready to take a reading.
3. Remove the MicroCure ® from the DataReader and place it in the UV process with the optics aperture towards the UV source.
NOTE: The MicroCure ® must be exposed to UV energy within four minutes after being reset. Otherwise, the MicroCure ® it will go back into standby/sleep mode. The DataReader automatically shuts down after thirty seconds of inactivity.
4. Remove the MicroCure ® from the UV environment and place it back into the slot in the DataReader.
5. Press the SELECT button. The DataReader will display the total UV energy in Joules per square centimeter (J/cm²) or the irradiance in Watts per square centimeter (W/cm²). Press and hold the SELECT button to toggle between total energy and irradiance.
6. Press the RESET button when the reading is displayed to clear the current reading and to set the MicroCure ® for its next reading.

Error Messages
The DataReader displays error messages if there is a problem with it or the MicroCure ® .
If "---" is displayed, communication between the MicroCure ® and the DataReader has failed. Re-insert the MicroCure ® into the DataReader and retry.
If "LO BATT" is displayed, the MicroCure ® 's battery is low. If this occurs within a 200-reading/ 1-year period from date of purchase, the unit or battery may be defective. The battery in the MicroCure ® is not user replaceable, contact EIT Instrument Markets for assistance. When the DataReader's battery is low, it will scroll "LO" ten times and then shut down. The battery in the DataReader is user replaceable. Refer to the Maintenance section of this manual for replacement instructions.
If the DataReader displays a numeric error code, contact EIT Instrument Markets for assistance.

High Speed Application
The MicroCure ® 's sample rate of 2048 samples per second produces accurate readings at high system speeds. Since total energy readings are directly proportional to exposure time, a reading for a high-speed system can be derived from a reading taken at a lower speed. For example, if the system speed is 600 feet per minute (fpm), jog the system down to 60fpm and take an energy reading. This reading represents the UV total energy of the system at 1/10 th the speed. To translate this to 600fpm, simply divide the energy reading by 10.
NOTE: Irradiance readings with the MicroCure ® should be consistent and are not dependent on speed. The MicroCure ® should register similar irradiance readings when consistent data collection techniques are .
The irradiance values displayed by the MicroCure ® are instantaneous peak irradiance values versus average or RMS irradiance values. The irradiance values are similar to the irradiance values collected with EIT instruments used in the “Smooth Off” (instantaneous peak) mode versus “Smooth On” (average peak) mode.

Maintenance
MicroCure® Radiometer Clean the MicroCure ® Radiometer's aperture with a cotton swab and isopropyl alcohol. Use isopropyl alcohol and a soft cloth to clean the case of the MicroCure ® .
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 Instrument Markets. It is specified to take 200 readings or last for approximately one year. Once the unit meets one of these conditions, it must be replaced.
The MicroCure ® Unit contains a battery. Any expired MicroCure ®  units may be returned to EIT for proper disposal of the battery.

DataReader
The DataReader only requires occasional battery replacement. The DataReader will indicate a low battery condition by scrolling "LO" across its display.
1. Remove the two screws from the plate on the left side of the DataReader.
2. Remove the battery and replace it with a new 9-volt lithium or alkaline battery.
3. Reinstall the access plate and screws.
