In alternate display mode, upper readout shows field intensity on x axis and lower readouts show field intensity on y and z axes.
MEM button. Used to: a) Manually store displayed reading(s) in meter’s internal memory at indicated location number; b) Begin automatic logging of three-axis EMF readings onto MicroSD card at selected sampling time, and c) Erase contents of meter’s internal memory and contents of MicroSD card.
Complete Setup by carefully removing the plastic film protecting the LCD. OPERATING INSTRUCTIONS MEASURING REAL-TIME EMF INTENSITY To power on the EMF1394DL, press and hold the green button (Callout 2) for at least 3 seconds. The unit will sound a long beep and the LCD will illuminate.

If you do not carefully note the positions of the MicroSD card and bracket as you move the bracket and remove the card, replacing the MicroSD card in the meter will be difficult. The photos on the previous page should help. If you do not re-install the card correctly, instead of seeing SdHC 2.0 on the LCD during the next meter startup you will see the following message: Sd Card Fail.
