開始測定
.按下電源開關接通電源。
.按下“FUNCTION” ,按加速度-速度-位移的順序切換測定模式。接通電源時顯示上次關斷電源時的模式。
.加速度的單位為m/s2 (PEAK),表示平均每秒的速度變化率。地球重力加速度1G 為9.8ms/S2 。
.速度單位為mm/s (RMS)。振動會使速度一直發生變化。振動計顯示速度的實效值。
.位移的單位為mm/s (P-P)。表示實際振動的振幅的全振幅。.讀取顯示的值后測定結束。
.持續按下POWER 數秒鐘后關斷電源。
決定測定模式的方法
.用位移(Displacement )模式測定
顯示振動物的實際振幅。以雙振幅顯示。
例如,顯示為30 umP-P (測微計峰值to 峰值)。這是三種模式中最易懂、最為普及的測定方法,適合于測定不平衡等旋轉的振動。頻帶窄,以10 Hz 到數百Hz 左右為對象。
.用加速度(Acceleration )模式測定
振動是按一定周期反復進行的運動。因此,動的速度和方向是一直變化著的,是發生速度變化的。加速度表示單位時間的速度變化,單位為m/S2 ( peak ) ,過去經常使用的G為1G = 9.8m /s2 。加速度的大小與頻率的平方成比例,適合于測定軸承老化等高頻率的振動。旋轉機轉動一周軸承轉動數十到數百周。此外,因傷痕、欠缺等會發生沖擊性脈沖,要檢測這些對象時適合于用加速度模式進行測定。
.用速度(velocity )模式測定
振動是按一定的振幅反復進行的運動。速度是表示一定的時間內位移了多少,表示振動的速度。該值與位移和頻率成比例,單位為mm/s(RMS)。頻帶在加速度和位移的中間,以10~1000 Hz 為對象。在大多數情況下,這時的頻率即使換為轉數實際上也無妨。(例:2400rpm ÷60 秒=40Hz )
DIGI VIBRO 與記錄儀連接
DIGI VIBRO 不僅僅是讀取振動的值,還能對振動的波形進行觀測和記錄,與具有FFT 功能的記錄儀連接還能進行頻率分析。
.與示波器連接,觀測振動的波形。用不同的測定模式,可分別獲得加速度、位移和速度的波形。
.將數據輸入電腦。
用市售的模擬/數字轉換器與電腦連接后,可將波形數據輸入電腦。利用應用軟件還可進行頻率分析。

Method for the determination of mode decision
With displacement (Displacement) mode determination
The amplitude of vibration of the animal show. Thedouble amplitude display.
For example, showed 30 umP-P (micrometer to of peak to peak). This is the most easy to understand, three modes of the determination method of universal, suitable for the vibration in the determination of unbalance rotation.Narrow band, with 10 Hz to hundreds of Hz around theobject.
With acceleration (Acceleration) model determination
Vibration is repeated by a certain periodic motion.Therefore, the speed and direction of motion is always changing, is the velocity changes. Acceleration velocity change per unit time, the unit m/S2 (peak), used to G 1G = 9.8m /s2. The size and frequency of the acceleration is proportional to the square of the aging, suitable for the determination of bearing vibration of high frequency.Rotary rotate a week bearing dozens to hundreds ofweek. In addition, due to lack of scar, will shock pulse, todetect these objects suitable for the acceleration modedetermination.
With speed (velocity) mode determination
Vibration is repeated by a certain amplitude motion.Velocity is expressed within a certain period of timedisplacement and how much, said vibration speed. The value and the proportion of displacement and frequency,the unit mm/s (RMS). The band in the middle of the acceleration and displacement, using 10~1000 Hz as object. In most cases, the frequency that is revolutionactually it anyway. (example: 2400rpm / 60 seconds =40Hz)
