Alignment - proFEX MG-200 Manual

4.3 Alignment

On a 5 by 5 foot area free of anomalies check the readings of the device while turning around. You need
to see the difference in readings between North and South, and East and West. While turning the
sensors should be located above the center of the chosen area and the device is held vertically. Begin
alignment from the pair of directions where the spread of readings is larger.
1 Enter the Alignment mode and press button 7 "OK".
2 Choose the pair of directions that has larger spread in readings – North-South or East-West using
buttons 2← or 5→. If for example, the spread is larger in the direction of North-South, press button
2←. "North" will begin to blink.
3 Orient the device to the North (the device is held vertically during the entire tuning procedure).
Press 7 "OK". Instead of "North", "South" will begin to blink.
4 Orient the device to the South, press 7 "OK" (Pic. 4 a,b).
If the screen says "Surpassed regulation zone", it means that the difference between measurements
in opposite directions surpassed 100 units. Repeat paragraphs 3 and 4 but without completing a full
turn so that the difference between directions is no more than 100 units.
5 Check the result by orienting to the "North". Continue repeating paragraphs 3-5 until difference in
measurements between positions to the North and to the South is no more than 2-3 units.
6 Perform the same procedure in the direction of East-West. After finishing check the reaction of the
device in all directions once more. Correct again if needed.
7 Return to Menu and save the settings through "Save Parameters".
Return to "Balancing" and check it too.
If during alignment tuning you turn in the wrong direction and press "OK", the device will calculate
wrong data and show the result that will be too high and difficult to refine. This can happen during
either alignment or balancing.
In this case simply choose through Menu "Default Settings", press 7 "OK", and repeat balancing and (or)
alignment tuning again.
