bCtrL
– Permission to control the counter using the meter keypad. The control
functions using the meter buttons are enabled for ON setting. The following
operations can be done using the keypad: start/stop counting, counter reset.
•
SAVG
– the setting defines for the counter mode only data acquisition period for the
averaging algorithm using the moving window method. The setting defines the
multiplicity of 100 milliseconds, e.g. data acquisition period is 1000 ms for the
setting 10.
•
MAVG
– number of the measurements with a period based on SAVG setting defines
the time interval in which the minimum and maximum value will be determined.
Counting the average value using the moving window method in the counter mode
is not available.
•
MatH
– type of the mathematical operation converting the value of counted pulses.
The user can select the type of operation or disable the function by selecting
NONE
setting.
•
CFtIM
– not applicable.

Period measurement
Measurement main features:
•
Wide range of period measurement (from 50
s to 60 s) with the possibility of
limiting the measurement time.
•
High measurement resolution.
•
Programmable measurement time (gating).
•
Automatic change of the measurement method depending on the frequency of the
input signal (counting the internal pulses within the input signal period or counting
the number of the external pulses in the set gating time).
•
High frequency of the internal reference signal generator (39 MHz).
•
Input waveform filtering (for duration of a given level > 50
s).
•
Additional frequency measurement.
•
Possibility of simple measurement conversion by multiplying or dividing by a
constant.
•
Possibility of measurement averaging using the moving window method with
registering the minimum and maximum value in a given averaging time.
•
Active math functions.
•
Active individual characteristic.
