1.Preparation
1). Check the voltage of the battery:
Press M<easure> key, observe the display on the screen. If
there is an arrow on the top left corner, you need to replace the
battery with a new one.
2). Set-up probe
HG908 with outside accelerometer has 1 probe and 1 magnetic mount.
When changing, take hold of the accelerometer to avoid rotation and
damage of the cable.
2.Measurement
1). Select the measure parameters:
HG908 has 4 vibration parameters. They are:
a) Displacement(unit: mm=1/1000 mm): Equivalent peak-peak value
b) Velocity (unit: mm/s) : True RMS Value;
c) Acceleration (unit: m/s2): Equivalent peak
d) High Frequency Acceleration (unit: m/s2): Equivalent peak
2). Functions of the M<easure> key:
a).Key press: Power on and begin measuring;
b).Key release: Hold the last measured value for twenty seconds and
then power off automatically.
3). Stick the probe to the measured object (the pressure should be
about 0.5-1 kg.)
3. Notes
1). Avoid intense impact, high temperature and immersed in water.
2). Keep the sensor plug clean and dry, and use it carefully.
3). Install the battery:
a) Open the small back cover of battery cabinet (2 screws at the
end far away from the sensor at backside, see figure);
B) Place a battery (6F22, 9V) correctly according to the polarity;
C) Close the back cover and screw the tightly;
D) If it has been put aside long-term, please take out the battery
To avoid the battery liquid;
4) If the sensor has been used for over one year,
please re-calibrate the sensor and the meter together to ensure the
precision.
4. Specifications
1). Measurement condition:
Temperature: 0oC -45oC, Humidity<
85%, Non-causticity environment,
without strong electric-magnetic field & strong impact. It can be
used in industry location by controlling the EMC
environment throughout installation and/or usage.
2). Amplitude Ranges:
Below 1 1999 m peak - peak (*)
True RMS Velocity 0.1 199.9 mm/s
Acceleration and High Frequency Acceleration:
0.1 199.9 m/s2 peak (*)
*Note: peak-peak and peak are equivalent value means:
peak-peak=2.828*RMS while peak=1.414*RMS
3). Accuracy: 5% of display digit 2
