C.T. is the abbreviation of component test,it is an application of oscilloscope for testing FET.Transistor.Diode,Zener,Inductor,Capacitor etc.which are in working or damaged.
On this oscilloscope the tested component is connected in component test jacks(5),press C.T.button,the trace on CRT oftested component should be displayed the characteristic trace of components are listed in appendix.
C.T.(元件測試)
C.T.是元件測試的縮寫,這是將示波器用於測試場效應晶體管、三極管、二極管、齊那二極管、電感、電容等,它們可以是正在工作的,或者已損壞的。在本示波器上,被測元件被連接到元件的測試插孔(5),按下C.T.按鈕,被測元件在陰極射線管上的徑跡應該被顯示。元件的特征徑跡列於附錄中。

22.X-Y
Pressing the X-Y button apply the vertical signal to the CHI or Y input connector and the horizontal signal to the CHⅡ or X input connector and the positioning on the screen can been vertically controlled by CHI position control knob.
X-Y
按下X-Y按鈕就向通道I或Y輸入連接器施加垂直信號,而向通道II或X輸入連接器施加水平信號,而在熒光屏上的定位可以用通道I位置控制旋鈕垂直控制。
23.HOLD OFF
Provides controls of hold off time between sweep signals to
obtain stable display when triggering an aperiodic signal.The control hold off time ranges is form 1 to 10 times of timebase.
保持
對掃描信號之間的保持時間提供控制,以在觸發非周期信號時獲得穩定的顯示。控制保持時間為從1倍到10倍的時基。
24.VAR
1.Provides continuously variable sweep rate by a factor of 2.5.
2.Light is turned on when VAR is not at cal position.
可變
1)以2.5倍提供連續可變的掃描速率。
2)當VAR按鈕不是處於定標(cal)位置時,燈接通(發亮)
25.X-POS(PULL*10)
1.Posotions the display horizontally.
2.pull 10:increases the dispalyed sweep rate by a factor of 10.
X位置(拉*10)
1)水平定位顯示
2)拉10:以10倍提高顯示的掃描速率。
26.CALIBRATION(CAL)
Provides about 1 KHZ 0.2V square wave to calibrate probe frequency compensation.
定標(CAL)
提供大約1kHz 0.2V的矩形波,以定標(校準)探頭的頻率補償。
27.SINGLE
Provides single sweep function after a sweep is displayed,further sweeps can't be presented until reset button is pressed again,during sweep is triggered.
單
在掃描被顯示後,提供單壹的掃描功能,在掃描得到觸發的過程中,直至再次按壓復位(reset)為止,否則進壹步的掃描不能呈現出來。
28.RESET:(Reference item27)
1.In single sweep wwaiting for a coming sweep and sweep is triggered,pressed reset button to obtain a single sweep.
2.An LED located above reset button indicate single sweep is operating.
復位:(參見第27條)
1)在單壹掃描中,等待就要來臨的掃描和掃描的觸發,按下復位按鈕獲得單壹掃描。
2)位於復位按鈕上方的發光二極管指示單壹掃描處於工作狀態。
29.EXT TRIG
Form the connector the outside signal can be input whih is taken for a trigger signal.
外部觸發
從該連接器,可以輸入外部的信號,被取作觸發信號。
30.TRIG SELECTOR
1.I:A sample of the signal derived form the CH1 input connector is used as a trig signal.
2.Ⅱ:A sample of the signal derived from the CHⅡ input connector is used as a trig signal.
3.I/Ⅱ:Alternative trigger which can triggter I and Ⅱ alternatively.The function is used in alternative dual trace of vertical mode operation.
4.EXT:Trigger signal is obtained form EXT TRIG connector.
觸發選擇器
1)I:壹個從通道I輸入連接器得到的信號的樣本,被用作觸發信號。
2)II:壹個從通道II輸入連接器得到的信號的樣本,被用作觸發信號。
3)I/II:可以交替觸發I和II的交替觸發器。該功能用於以垂直模式工作的交替雙蹤示波。
4)EXT(外部):觸發信號來自於外部觸發(EXT TRIG)連接器。
31.TRIG COUPLE
1.AC-Rejects dc and attenuates signal about 100HZ,accepts signals above 100HZ.
