Reference mode is helpful if you wish to hear an audio alarm whenever the RF
exceeds a certain level. If any of the reference modes are enabled, you should
see the REF label shown back in the main screen. The bottom line of the display
will 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 RF signal is higher than the reference, the difference is a positive
number and an alarm is activated. In the example display shown, the difference
is 1.453mV, the reference is 0.700 mV, therefore the actual RF signal peak is
2.153 mV.
Adjust the reference settings by pressing the THRESHOLD and NAVIGATOR
buttons.
When data is being recorded, the actual peak value above the reference setting is
recorded, not the “difference” value.
DATA STORAGE and READ (RF Signal Sensor)
The RECORD button (“R”) writes the displayed readings and settings onto the microSD
™
storage card; press the “R” button to activate RECORD. At this point, the button turns red
and data is being written onto the storage card. To stop recording, press the red button
again.
The recording works in conjunction with the settings made on page 25 (Intervals), and/or
pags 25-26 (Reference) of this User’s Guide.
A data line is recorded based on the timing interval which was preset at the “Intervals”
menu.
It is also based on the settings for References on pages 25-26. If any of the references
are enabled, a data line is added within the preset interval whenever a peak signal was
detected above the reference setting. If the Reference is not enabled, data lines are
added at intervals showing the current peak and average signals.
The DATA STORAGE button displays the data stored on the microSD
™
card found at
the bottom of the meter. Press this button to show the SD
™
card history screen. Scroll
through the data recorded using the NAVIGATOR button.
Note: If an “X” mark is overlaid onto the DATA STORAGE button, a noncompatible SD
storage card is inserted. (See Data Storage section.)
