2. APPLICATIONS

This meter is specially developed for measuring or

monitoring electromagnetic field, for example:

cell-phone station, hospital equipment, radar ,

micro-wave oven, radiation work, TV antenna , Radio

station , welding equipment , baking- equipment,

television , computer , factory, laboratory , and other

environment...etc.

3. SAFETY INSTRUCTIONS

Danger

* For worker's safety, be aware that persons with

electromagnetic implant ( e.g. cardiac-pacemarker ) are

subject to especial danger in some case.

* Particular to observe the local safety regulations of the

operator of the equipment.

* Before using the device, it need to know that how to

setting " alarm-limit " value ( refer to page 10 ).

Attention

* Claims by some scientists that long term exposure to

electromagnetic field may be the cause of childhood

leukemia & other forms of cancer.

* Complete answers to any of these and related

questions are not currently available. At the present

time the most common practice is to avoid excess

exposure over long period of time.

* Complete answers to any of these and related

" Prudent Avoidance " as stated by the Environmental

Protection Agency(EPA) USA is recommended.

* According to ICNIRP of reference levels to time-varying

electromagnetic fields. The E-field strength levels are:

6. MEASUREMENT CONSIDERATION

1)Connect the " Probe Plug " ( 5-18, Fig. 1 ) into the

" Probe Input Socket " ( 5-9, Fig. 1 ).

2)Plug in the exclusive " Probe Memory Card " ( 5-10, Fig.

1 ) into the front end socket of meter.

Remark :

* Probe memory card is saved the Probe's

character into the internal memory circuit.

* Each probe should cooperate its own exclusive

" Probe Memory card ", do not plug the

another card, otherwise the accuracy will exist

certain deviation.

* If intend to make the measurement precisely.

Make sure to use the " Frequency Team Button " ( 5-5,

Fig. 1 ) ) to select the convenient point that according

the measurement object.

Consideration :

* There are two frequency selection points :

Normal, 2.45 GHz.

* The default selection is " Normal ", however if

the measurement frequency is microwave or

its frequency is near " 2.45 GHz ", it should

select to " 2.45 GHz " will get the high

precision.

3)The meter is build in the 3 axis ( X, Y, Z ) EMF sensors,

the circuit measure each X, Y, Z sensor's EMF value, then

the CPU will calculate the total EMF value according

the following formula :

X : The EMF value that sensing from the X direction.

Y : The EMF value that sensing from the Y direction.

Z : The EMF value that sensing from the Z direction.
