Electromotive force will be generated when the current flows through the wire or when the electrical and electronic equipment is working. Electromotive force phenomenon exists in many places of our life and work.
GREEN: "Normal" zone — Normal background Magnetic Field: 0 to 1.5 milliGauss
GREEN: " Low" zone- Low-Level Magnetic Field: 1.5 to 2.5 milliGauss
YELLOW: "Caution" zone-Mid-Level Magnetic Field: 2.5 to 10 milliGauss
ORANGE: "High" zone-high-Level Magnetic Field:10 to 20 milliGauss
RED: "Warning" zone-Extremely high Magnetic Field:20+milliGauss
1)Hold the EMF METER with your thumb on the switch
2) Point it toward the EMF source,then depress and hold down the switch(a short flash of the
LED's will occur)
3) The LED will indicate the range of the EMF at that level
4) Moving the device from side to side or rotating it may change the reading;the highest reading
is most accurate
5) Move closer or further away to the EMF source to determine the"Normal""zone as indicated-
by the Green LED
| Material: | ABS Accuracy: +/- 5% |
| Detection Range: | 0 to 20+ milliGauss |
| Detection Frequency: | 30 - 20,000 Hz |
| Battery: | 1 x 9V batteries Package |
| Includes: | 1 x EMF Magnetic Field Detector |
Record the readings on the enclosed Exposure Logrepeat periodicallysince fields can change in strength
If the GREEN LED(Normal) doesn't light the battery is low
To change battery remove the two screws, replace 9V battery
