Stop using the instrument, when an object or liquid falls/spills into the
instrument. It causes fire or shock hazard.
Turn off the power switch and unplug the power cable from outlet as soon
as possible, please contact the agency or IMV.
Do not expose the instrument to moisture or dust.
If causes fire or shock hazard.
When replacing or disposing of the battery, follow the precautions on the
battery.
Also, pay attention to the polarity when replacing.

3-1. Before Getting Started
(1) You can select the computing method for velocity, acceleration, and displacement.
Refer to section 4-2 for more details. Initial settings are as follows:
■Acceleration (ACC): rms
■Velocity: rms
■Displacement: EQP
If you are familiar with our VM-7000L, EQP setting for the displacement is highly
recommended. Since the measurement data with the VM-7000L is indicated in EQP,
you may easily compare the data with the same setting.
(2) Check the polarity carefully, and set two AA batteries in the battery box (Ni-Cd or
Alkaline) (Fig.3-2).
For the use with the AC adaptor, connect the AC adapter cable to the power connector
in the bottom of the device.
(a) Installing AA batteries (b) Attaching the AC adapter

Pay attention to the polarity of the battery.
(3) Connect the pickup cable to the pickup connector.
In addition, when measuring, pickup installed or fixed for object. For actual measurement,
refer to the following sections.
Refer to section 10 when fixing the pickup.

When the Auto Range function is “OFF” (refer to section 4-4.), the range key will
be activated during measurement (Fig 3-4).
Touching “Range” on the touch screen or pressing “Function Button” will show the
range setting display. You may adjust the range accordingly.
The icon will appear on the upper right corner of the screen when the value is
over the range (Fig.3-5).
(2) About Excessive Input State (Measurement Impossible State)
When is displayed on the upper right of the screen, regardless of main unit
version, input speed value exceeds the hardware range (amplifier gain), and the
waveform is distorted and unsuitableness state.
In this case, do not use it as a measurement value because it is not possible to
measure accurately.

(1) A brief Description of each Calculation Method
rms: “rms” is “Root Mean Square”. This is the square root of the mean of the squares
of the time-series data gathered from measurement. ISO standard sets RMS as
evaluation criteria of the vibration velocity, which is also known as vibration
severity.
EQP: EQP is a value gained by “rms”× √2
. This formula is suitable to use for
measurement of sine vibration generated by rotational machines, for example.
Peak: The maximum value of the time-series data.
For detailed explanation, refer to the definitions in Section 10.
(2) Setting of VM-7000L
When had used VM-7000L in past, should not use “Peak” setting, but use the same
setting as VM-7000L.
Recommended setting for VM-7024H are as shown in the table below.

4-4-2. Self-Check Mode
By reversing the pickup vibration detection direction in the direction of gravitational
acceleration (vertical) and checking the static acceleration of ±9.8m/s2(±1G), it is
possible to easily determine whether there is a pickup abnormality.
(1) Connect an oscilloscope or digital voltmeter to DCOUT.
※Device is select "DC measurement mode".
(2) “DC OUT Sens” select 30m/s2/V (refer to section 4-5)。
(3) Self-check is “ON”.
(4) When pressed “Measurement Button” and measurement is started, the display
automatically changes to the range of 20m/s2rms and the numerical value is displayed.
(5) If the detecting arrow mark of pickup is set upper direction or lower direction for ground,
pickup will generate a static acceleration of approximately ±9.8m/s2by the gravitational
acceleration.
(6) Since DCOUT Sens is 30(m/s2)/V, it is good if about 0.327V±5% is output
(7) Next, if the detecting arrow mark of pickup is set horizontal direction for ground, output
voltage and acceleration value is approximately zero.
(Japanese) (English)
Fig.4-11 Setting Page of Self-check
When using this mode, regardless of the measurement mode setting (Fig.4-
1), the top
display is acceleration, and the range is fixed at 20m/s2rms (range change is disabled).
After the self-check is completed, set the self-check to “OFF” on the setting screen (normal
vibration measurement cannot be performed if the self-check is left on).
