RF Field Strength Meter RF-194
1 Introduction This meter is designed for measuring and monitoring electromagnetic field value of the Radio –Frequency The meter is calibrated precisely on the frequency value 2.45 GHZ 2 Application This meter is applied to measuring electromagnetic fields of Radio –Frequency of normal or 2.
4 Identifying Parts 1. Sensor position. 2. LCD 3. Zero button 4. Power on/off 5. maximum hold and minimum hold select button 6. Frequency Team select button 7. Data hole button 8. Tripod mounting screw 9.
5 Measurement Procedures Press button to power on. Press button test frequency to select 2.45 GHZ or normal (50MHz to 3.5 GHz). Position the top (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). Due to the environmental magnetic field factors, this magnetic field meter could display a reading value that is lower than 0.002 mW/cm^2 prior to measuring.
Figure 1 indicates the correct measurement direction of the RF electromagnetic field strength measurement. Figure 2, 3, 4, 5 and 6 indicate the incorrect measurement direction of the RF electromagnetic field strength measurement. AUTO POWER OFF function 1. In order to save the battery power the meter will be off after 30 minutes of non-use. 2. To disable this function please turn off the power then hold MAX/MIN key ,press power key. 3.
