Relative Humidity will be displayed in the primary display and the temperature will be displayed in the secondary display. 4. Press the up or down arrow button to change the temperature units. 5. Press the MODE button to display the DEW point. 6. Press the MODE button to display GPP (°F) or g/kg (°C) Pinless Moisture Measurements 1. Press the power button to turn the meter on. 2. Press the MOIST button to select Moisture measurement.” MOIST”,”REL” and “INT” (internal pinless sensor) will appear in the display. 3. Hold the meter so that the rear sensor is away from any surface or your hand. The reading should be near 0.0. If not, press and hold the ZERO button for more than 2 second and the ZERO icon appears. 4. Place the rear sensor on the surface of the material to be tested and read the relative moisture content. Pin Type Moisture Measurements 1. Connect the external pin probe to the jack on the bottom of the meter. 2. Press the power button to turn the meter on. 3. Press the MOIST button twice to select Moisture measurement.” MOIST”, “%” and “EXT” (external pin probe) will appear in the display. 4. Press the probe pins into the material and read the % moisture content in the display. MO290 V3.0 03/09 5 Infrared Temperature Measurements 1. Press the power button to turn the meter on. 2. Press the IRT button to enable the IR thermometer and the laser pointer. The laser pointer icon will flash while the mode is active. 3. Press the up or down arrow button to change the temperature units 4. Aim the laser pointer at the surface to be measured and read the surface temperature in the secondary display. 5. Release the IRT button. The last temperature measured and the laser icon will remain on the display for approximately 10 seconds before returning to ambient temperature measurement. IRT MAX MIN display: The meter can be set to display only the maximum or minimum temperature measured during an IR scan. 1. With the meter in the IR hold mode, press the MODE button. “MIN” will appear in the display. 2. Press the IRT button to enable the IR thermometer. The meter will display the minimum temperature measured and will update only when a lower temperature is measured. 3. Press the MODE button twice to enable the MAX mode and proceed as stated above for the maximum temperature. 4. The MAX or MIN temperature is not stored when the function is exited. IR Field of View Ensure that the desired target is larger than the spot size. As the distance from an object increases, the spot size of the area measured by the meter becomes larger. The meter’s field of view ratio is 8:1, meaning that if the meter is 8 inches (cm) from the target, the diameter (spot) of the object under test must be at least 1 inch (…

Hopping Information 1. Hopping Range Hereby we declare that the maximum frequency of this device is: 2402-2480MHz. This is according the Bluetooth Core Specification V1.2 for devices which will be operated in the Europe. This was checked during the Bluetooth Qualification tests. Other frequency ranges (e.g. for USA, China, Japan) which are allowed according the Core Specification are not supported by this device. 2. Hopping Sequence Example of a 79 hopping sequence in data mode: 33,04,21,44,23,42,53,46,55,48,40,59,72,29,76,31,08,73, 07,75,09,45,60,39,58,13,47,11,77,52,35,50,65,54,67,56, 69,62,71,64, 37,25,27,66,57,70,74,61,78,63,10,41,05,43, 15,44,64,68,02,70,06,01,51,03,55,05,03,66,53,49,36,47. 3. Receiver input bandwidth The input bandwidth of the receiver is 1MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packer has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence.
