Reference mode is helpful if you wish to hear an audio alarm whenever EMF
exceeds a certain level. If any of the reference modes are enabled, you should
see the REF label shown on the main screen. The bottom line of the display will
now show the reference value of the peak signal. PLEASE NOTE: The top line
shows the “difference” (not the PEAK as labeled) between the ACTUAL PEAK
measured and the REFERENCE setting. Therefore, whenever the “actual peak”
value of the EMF signal is higher than the reference, the difference is a positive
number and an alarm is issued. In the example display shown, the difference is
0.105 V/m, the reference is 0.010 V/m, therefore the actual peak is 0.115 V/m.
Adjust the reference settings by pressing the THRESHOLD and NAVIGATOR
button.
When data is being recorded, the actual peak value above the reference setting
will still be recorded.
Memory and Current Reference
These references are used for convenience. The “memory” reference is the
value which is stored in the memory all of the time and saved when the device is
powered off or when the main battery is removed. The “current” reference is the
average value of the measured signal (background noise shown in PEAK value)
which was detected by the unit, when you entered into the reference menu. If
you enable this reference, it works the same way as the memory reference. When
you disable it and switch back to the main menu, this value is lost. Current
reference is useful to detect signals with the level higher than background noise.
