-1-
1-1 GENERAL MODEL VM-13V1 Vector Monitor continuously measures the vibration vector
(amplitude/ phase angle). The VM-13V1 accepts the phase reference signal (1 pulse/
revolution) and the vibration inputs and indicates the vector data (amplitude/ phase
angle) of the selected vibration channel and rotating speed on front panel LED
displays. The recorder signal outputs of each data are available on front panel panel
BNCs and rear panel terminals.

! NOTE
This monitor provides the peak to peak rectifying circuit for O/A (overall) amplitude. Therefore,
depending on the vibration waveform, this monitor might indicate a little higher O/A amplitude
level than other average rectifying type vibration monitor installed at the same machine.
1 RPM Display 5-digit display indicating the shaft rotating speed.
Display range : 200 to 99,999rpm
2 AMPLITUDE Display 3 1/2-digit display indicating displacement amplitude in peak to peak
selected by the Vibration Input Channal Selector Switch ( 14 ).
Display range : 0 to 500µm or 0 to 19.9mils
3 PHASE Display 3-digit display indicating phase angle selected by the Vibration Input Channal
Selector Switch ( 14 ),when the VM-13V1 is operated in FILTERED mode.
Display range : 0 to 360deg.
Note) The display is blanked in O/A mode.
4 AMPL. Unit LED Iindicating the amplitude unit (µm or mils )by illuminating the corresponding
LED.
Note) For unit selection, see 4.3.5 6 on page 17.

5 AMPL. Mode Selector
Switch
Used to seleect the amplitude mode of operation.

O/A : Overall vibration (Peak to Peak)
Note) The PHASE Display ( 3 ) is blanked in O/A mode.
6FS Range Selector Switch
Used to select full scale range of the amplitude.
Metric mode : 125µm / 250µm / 500µm
Inch mode : 5mils / 10mils / 20mils

exceeds the selected full scale.
7 1N/2N Selector Switch
Used to select frequency multiplier (N), when selecting FILTERD mode by

rotating speed.
8 Band Width Selector
Switch
Used to select filter band width when selecting FILTERD mode by the
AMPLMode Selector Switch ( 5 ).

2Hz : Band width is 2Hz.
AUTO : Band width is 0.2Hz below 1,000rpm.
Band width is 2Hz at 1,000rpm or more.
Note) In 0.2Hz, the response of the amplitude and phase output
(display) will become very slow.
9 Trigger Mode Selector
Switch
Used to select the trigger mode (AUTO/ MANUAL) for the reference input
signal (1P/R). In the manual (MAN.) mode, the threshold level should be
adjusted by the LEVEL potentiometer ( 12 ).
10 Trigger Input Selector
Switch
Used to select the trigfer signal source.
NORM : Input from the rear 1P/R NORM terminals.
AUX : Input from the rear 1P/R AUX terminals or the front panel
AUX IN TRIG. connector ( 13 ).
