Pause key
Three selections are available: Any key , Alt+F1 , and Ctrl+F5 . This feature is used to
pause data recording during logging session. Default setting Any key can be changed to
one of the two key combinations for field conditions where a logger key can be accidentally
pushed causing unwanted stop of data logging.
Display
This parameter specifies the display type during data collection. Two types of the display
can be selected: Text mode or Graphic mode.
In the text mode data for four channels is displayed in digital form. This mode is
recommended for the instrument AUTO mode when the highest possible frequency of
data collection is used. The same applies to Wheel mode since the data triggering can be
accelerated at any given moment (while passing a curb, downhill, etc.).
The graphic mode allows to display profiles for any selected channels in real time as well as
simultaneous display of readings in digital form for all four channels. When the Display
Graphic is selected, five additional parameters are activated (see menu below).
Parameters Ch 1 , Ch 2 , Ch 3 , and Ch 4 (applies to Ch T as well ) allow you to enable (Yes)
or disable (No) display of each channel separately, while the option Amp . (Amplitude
Scale) can be selected as Compressed scale or Linear scale. The compressed amplitude
allows you to display the high dynamic range of the EM61-MK2 data in a legible way and
is recommended.
Regardless of which channels are chosen, data for all four channels will be displayed in
digital form below profile display.
Please note, that readings in digital form are always given in mV (linear scale) regardless
of the amplitude scale (compressed or linear) selection. Further, graphic display in the
compressed scale does not affect readings saved in the data file. Data are always written to
file in original form.
After all the parameters in the Logger Setup menu are updated press the function key F1 to accept
the displayed settings. The program will return to the Main menu.
To return to the original settings (state before this option was selected) press the function key F2 .
All parameters will be reset to the initial settings and the program will return to the Main menu.
