Specifications:

1). Measurement condition:

Temperature: 0^oC -45^oC, Humidity<85%, Non cousticity 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:

Displacement 1-1999mm peak-peak (*)

Velocity 0.1-199.9mm/s true RMS

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). Measurement accuracy: ± 5% of display ± 2 digits

Noise Level (without input): ACC<0.3m/s², VEL<0.5 mm/s, Disp<3mm

Frequency response accuracy: ±5%; (±10% for ACC 4.5kHz-10kHz)

Non-linearity: ±5%

4). Sensor type: Shear type Piezoelectric Accelerometer

5). Frequency response: 10-1000Hz (Inside accelerometer)

10-5000Hz (Outside accelerometer, depending on model)

High Frequency Acceleration: 1000-5000Hz ±10%

6). Battery: 9V 6F22, 25 hours of continuous operation.

7). Configuration:

Standard: Outside accelerometer with magnetic mount and probe

Optional: Inside accelerometer with 2 handheld probes

8). Dimensions: 13´6´2.3 cm; Weight: 250 g.

Configuration:

HG908: Separate accelerometer with magnetic mount & probe, long needle probe
Battery: 9V 6F22/Rechargeable, 25/10 hours of continuous operation.
Pickup: Accelerometer with handheld probe and/or magnetic mount
Dimensions: 13×6×2.3 cm; Weight: 200 g
Optional Intrinsically safe version with internal accelerometer

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.)

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 screws tightly;

d) If it has been put aside long-term, please take out the battery
