Table 1
t_H1
Minimal duration time of the high level
pulse on the main input. The introduc-
tion of a value lower than 0.25 or 5
causes the switching of the length con-
trol function of the high signal level off.
The value is given in milliseconds.
Parameters t_L1 and t_H1 define the
maximal frequency value.
(minimal signal period = t_L1+t_H1 + 0,2s).
0...60000
E_In1
Permit for external functions: start/stop,
erasing. Taken into consideration only
in counter modes: pulse counter and
worktime counter. The meter counts
only by the passed high level signal
on the input W1 near external func-
tions switch on the worktime counter.
bUt – External functio switched
off. Access to functions only
from the level of meter buttons.
In – functions switched off.
External functions switched
on. Access by means of but-
tons is switched off.
bUtIn – External functions
switched on. Access by means
of buttons and additional
inputs. Higher priority have
external inputs. The option of
the counter erasing is available
from the keyboard level.
Auto1
In the counter working modes, the
counter value is automatically erased
after reaching this value. The write of
the value 0 switches the function off.
In the working mode of low frequency
measurement, speed, periods, it is the
time in seconds of the measurement
duration (waiting for the pulse).

Cnt1
The measurement time is expressed
in seconds. The result on the display
presents the mean value counted in
the Cnt1 period. This parameter is not
taken into consideration during the
measurement in counter modes.
