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.)
