10
The FM 2000 offers a new measuring method which allows to measure with a 10-times
accuracy without a substandial increase of the measuring time. However the last two digits
will need about 10 seconds before the correct value is indicated.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
5678
67358
MODE 3
: Shifting of the display with additional 0
For lower frequencies it may become necessary to abtain a larger indication on the display
without the delay of 10 seconds for the measuring time. In this case the display is shifted
one digit to the left and a zero is added at the end.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
5670
67350
MODE 4
: Steady Display
Due to different measuring methods most instruments show a flickering of the last digit in
their display.The measuring method of mode 4 is the same as it is used for mode 2 but with
the intention to eliminate the flickering of the last digit.
example:
operating mode 0
Frequency meter
operating mode 1
Period Time meter
Frequency to be measured
567,8Hz
67,358Hz
Display indicates
567
6735
