or the " ACC ", " g ", " RMS " symbol.
b. For the Velocity measurement, press the
" Unit button " ( 3-6, Fig. 1 ) once until the display
show the " VEL ", " mm/s " and " RMS " symbol
or the " VEL ", " cm/s " and " RMS " symbol.
c. For the Displacement measurement, press the
" Unit button " ( 3-6, Fig. 1 ) once until the display
show the " DISP(P-P) ", " mm " symbol.
4)If the surface material of measuring article is not the
ferrous material, hold the vibration sensor by hand &
touch the sensor to the surface of the measuring
article, refer the Fig. 2.

display unit can be changed from the Imperial unit to
Metric unit or be changed from Metric unit to Imperial
unit.
The Metric unit are :
Acceleration measurement is m/s^2 or g.
Velocity measurement is mm/s or cm/s.
Displacement ( p-p ) measurement is mm.
The Imperial unit are :
Acceleration measurement is ft/s^2.
Velocity measurement is inch/s.
Displacement ( p-p ) measurement is inch.
4-3 Function selection ( RMS/PEAK/MAX HOLD )
During the Acceleration, Velocity, Displacement
measurement if press " Function/Send button "

Acceleration ACC ACC ACC
( LCD symbol )
RMS PEAK PEAK MAX HOLD
Velocity VEL VEL VEL

RMS PEAK PEAK MAX HOLD
Displacement DISP(p-p) --------- MAX HOLD
( LCD symbol )
11
1)Function 1 ( RMS for ACC, VEL., p-p for DISP. ) :
Function 1 is the basic operation function, for
general operation select the function 1 typically.
* If Acceleration function measure the " RMS " value,
the display show " ACC " and " RMS " symbol.
* If Velocity function measure the " RMS " value.
the display show " VEL " and " RMS " symbol.
* If Displacement functon measure the " p-p " ( peak to
peak ) value, the display show " DISP ( p-p ) " symbol.
The definition of " peak to peak ", please refer Fig. 6
2)Function 2 ( Peak , for ACC. and VEL, only ) :
* If Acceleration function measure the " Peak " value,
the display show " ACC " and " PEAK " symbol.
* If Velocity function measure the " Peak " value.
the display show " VEL " and " PEAK " symbol.
The definition of " Peak ", refer Fig. 5.
3)Function 3 ( Max. hold, for ACC., VEL and DISP. ) :
* If Acceleration function measure the " Max. peak "
value with hold. the display show " ACC " and " PEAK
MAX HOLD " symbol.
The definition of " Max. peak hold " value, refer Fig. 5.
* If the Velocity function measure the " Max. peak "
value with hold the display show " VEL " and " PEAK
MAX HOLD " symbol.
The definition of " Max. peak hold " value, refer Fig. 5.
12
* The Displacement function measure the max. " p-p "
( peak to peak ) value with hold, the display show "
DISP ( p-p ) " and " MAX HOLD " symbol.
The definition of " peak to peak ", please refer Fig. 6
*Max. hold reset :
If intend rest the " MAX HOLD " value, just
press the " Zero button " ( 3-3, Fig. 1 ) > 2 sec
continuously, the display will return to zero and
make the new max. hold value measurement
again.
