Function Selection:
Frequency and Rotate speed display Set
(Please d
isconnect the input signal
before setting when the input signal is
High level voltage signal)
Open the back cover
of the meter,
Press
"
S2
" key to enter "SET" model and then press "S1" to change display mode
,
"0"
means
Frequency display
with filter ;
"1"
means
rotate speed
with
filter;
"2
"
means
Frequency display
without filter ;
"3"
means
rotate speed
without
filter.
10 seconds
later,
this meter will
automatically
return
to
the
measurement mode
, or
power-off
and restart
, this meter still could
return to
measurement mode too
.

interface
,
"
S1
"
key   is
the shift key
,
"
S2
" key is the
value
plus
key
,
the
divider
value
must be set
in
1-99999
or
0.0001-9.9999
figures
, and   other
value
is
invalid
;After the
set
of
the desired
divider
value via
"
S1
" and
"S2
"
,
wait   10 seconds
and
the meter will
automatically
return
to
the
measurement
mode
,
or
power-off
and then restart
to
return
to
the
measurement mode
.
Divider
concept
:
The number of the singal the
gears get for one circle
.
For example
,
a
gear
can take
20
pulse signal
for one circle ,
the
divider
value
could be
set to
20.
High and Low voltage
signal input
switch
(
Please d
isconnect the input signal
before setting when the input signal is
High level voltage signal)
The
default set for this meter is
the
low voltage input
,
if you need
high-voltage input
,
you
need
to
open  the back cover
the more the short jumer from the "L
"
part.
Enter
the
high voltage directly
will
damage
the
meter
if the
short jumper is not removed.
We are not responsibility for this damage. Please
carefully
