Measurement starts with the active edge at the counter
input A. After the measurement time (1 sec) has elapsed,
the measurement is completed with the next active edge,
and the value is displayed in CHANNEL A.
If no active edge appears within the “time out” period
you have programmed, the rate meter is reset to zero.
At frequencies > 1 Hz the average is calculated. When
the allowable count frequency is exceeded, the value
zero appears in the display; if the possible display range
(99999999) is exceeded, the display “E” appears.

You can also set a fixed decimal point and
program the pulse counter so
that you can reset it either through the regular
electrical
reset on the back or through the red R key on
the front.

4. Installation – Battery replacement
After unpacking the instrument, remove the light-colored
frame from the back of the housing by simultaneously
bending both long sides of the frame slightly apart to
disengage them from the locking holes.
Then slide the housing through the cutout prepared in
the
front panel, attach the frame onto the back of the housing,
slide it all the way against the back of the front panel, and
carefully attach it with the two side screws to the front
panel.
In this way, you can compensate for different front panel
thicknesses. Class IP 65 front protection is achieved
through the seal integrated in the housing.
See the wiring diagram below for the electric wiring.
