1 General Information 1.1 Information about the user manual Congratulations on choosing the high quality and highly efficient Mikron blackbody. This manual provides important information about the instrument and can be used as a work of reference for installing, operating, and maintaining your blackbody. It is important that you carefully read the information contained in this manual and follow all safety procedures before you install or operate the instrument.
warranty information. This warranty covers manufacturing defects and faults which arise during operation, only if they are the result of defects caused by LumaSense Technologies. The warranty is VOID if the instrument is disassembled, tampered with, altered, or otherwise damaged without prior written consent from LumaSense Technologies; or if considered by LumaSense Technologies to be abused or used in abnormal conditions. 1.
The instrument must be shipped in the original packing container or its equivalent. LumaSense Technologies is not responsible for freight damage to instruments that are improperly packed. Contact us to obtain an RMA number (if one has not already been assigned by Technical Support). Clearly indicate the assigned RMA number on the shipping package exterior.

2 Introduction 2.1 Description The M305 blackbody calibration source design achieves significant weight and size reduction over the M300 with only minor sacrifices in specification and performance, making it an ideal unit where portability is required or space is limited. The spherical cavity yields an emissivity of 0.995 over the temperature range of 100 °C to 1000 °C with an aperture of 25 mm. An integrally mounted PID controller completes this versatile calibrator. 2.

3 Installation and Operation 3.1 Installation Install the blackbody emitter in the desired location that preferably has no moving air near the emitter aperture. The M305 has been factory wired to operate from your standard 100 to 120 VAC at 15 amps and requires approximately 1000 watts upon power up. Optional voltages are available upon order. Check the specification label in the rear prior to applying power. 3.2 Operation 3.2.1 Starting Up 1.
3.2.3 Shutting Down Turn off power using the power ON/OFF switch. Warning: DO NOT UNPLUG THE M300! The blackbody has a temperature controlled cooling fan that remains active until the enclosure temperature is below about 140°F. If the power is interrupted by external means, this cooling will not occur and the devices in the enclosure may overheat. If power fails during high temperature use, remove the top, rear cover plate to allow better convection cooling until the blackbody is cool.

The factory address setting is 1.
RS485 Option RS-485 Two wire is available as an option. The connection scheme is shown below: RS-485 for multi-drop applications Each M305 address must be set to a different value. To alter the address: 1. Press and hold PAGE button. The word ACCESS will appear in lower display. 2. Press SCROLL button. LEVEL 1 will appear. 3. Press UP button until LEVEL 3 appears. 4. Enter PASSCODE by pressing the UP button until 3 appears and wait until PASS appears. 5.
3.2.6 Controller Calibration This blackbody has a precision temperature sensor monitoring the emitter temperature. The THERMOCOUPLE measurements are passed through a look-up table that ultimately provides the correct exit radiance temperature for the indicated temperature. A separate calibration report is included. This controller has been programmed to contain a custom look-up table that may be used to precisely calibrate the controller/indicator against reference sensor.
Typical Radiance temperature calibration look-up table (LUT) used for this M305 To gain access to the custom look-up table: Refer to the 4 elliptical buttons on the face of the controller and use this procedure. 1 2 3 4 1. Press and Hold 1 until ACCESS appears. If Access Level and Level 1 appears, skip to step 3. 2. Press 4 until Level 3 appears. 3. Press 4 until 3 appears. Wait and "pass" appears. 4. Press 1 until Lin16 appears. 5. Press 2.
7. Press 2 to view/change more correction points. 8. When finished with all calibrations and to lock the controller, press 1 until ACCESS appears. 9. Press 3 until Level 1 appears. Note: Calibration points do not have to be used as pre-programmed. To dial in a different calibration point, simply change an INPUT # and the corresponding OUTPUT# to be the new desired calibration point. Set the blackbody to the calibration temperature using its setpoint.
5. After the program ‘sees’ the controller (a picture of a controller appears at lower left of screen). 6. Follow directions in Section 3.2.5 to access the controller radiance temperature LUT table. 7. Reset the communications mode to EIBISYNCH using the steps above except replace Modbus with EIBISYNCH in step 6 above.
