ZYPLVibration frequency testerInstructions

1. Vertically attach the magnetic suction seat at the bottom of the sensor to the device under test. When installing sensors, the surface of the base should be perpendicular to the vibration of the equipment. The sensor output line is connected to the host.

2. Turn the power switch to the "on" position, and it will be detected after 2 seconds.

3. When the "" indicator light on the display window is on, it indicates that the battery voltage is lower than the normal operating voltage, and the battery should be replaced in a timely manner (working current<10mA).

Precautions

1. Avoid hitting or knocking the sensor during use. The connection with the wire should not be twisted or pulled from the root.

2. The frequency range is also used for filtering. The frequency range is used to resist external interference, and appropriate upper and lower frequency values should be selected, otherwise there will be significant changes in the digital values of the frequency table.

3. Do not use gasoline or rubber water to clean the instrument.

4. When the instrument is not in use for a long time, remove the battery from the battery compartment behind the instrument to avoid battery damage.

5. When the instrument displays errors during the measurement process, consideration should be given to whether the battery is under voltage or whether the sensor is damaged.
