MG-300 1 Introduction Safety precautions should be taken against electric appliances in places including medical institutions, schools and residential districts, where people usually stay for a long time, to prevent patients, babies and senior citizens from exposure to high electromagnetic waves. An electromagnetic wave simply means the wave motion of the electromagnetic field (EMF).
MG-300 3 Features Switch between the display of micro-Tesla and milli-Gauss is available. Data hold (HOLD)、maximum (MAX) Hold function. Range display(20,200,2000). Low battery detector “ ”. Over load display “OL”. 4 Identifying Parts 1. Sensor position. 2. LCD 3. Power on/off. 4. maximum hold button 5. Data hole button 6. mG unit select button 7. µT unit select button 8. Range select button 9. Battery cover.
MG-300 5 Measurement Procedures Press to power on. Select for µT unit or Position the front (refer to Figure 1) of the meter to measure the electromagnetic waves. Try to change the measurement angle or position for obtaining the highest reading value (please refer to Figure 2 to 6). Read the measured value. The display of “OL” on the left highest position indicates there is an overload on the reading. Please press range for measurement again.
MG-300 Figure 1 indicate the correct measurement direction of the electromagnetic wave. Figure 2,3, 4, 5 and 6 indicate the incorrect measurement direction of the electromagnetic wave.
