三、电火花真空检测仪工作原理
Three, the electric spark vacuum detector working principle
接通电源后由L1与CD产生振铃，在CD的触点之间发生电火花现象，激励C及L2组成的回路串联谐振，经L3感应产生高频电压，然后由放电簧F放出高频电火花，即可使用。
After the power is switched on by L1 and CD for generating a ringing, electric spark phenomenon urred in the contact between CD, C and L2 excitation circuit composed of series resonant, high-frequency voltage after L3 induction, and then by the discharge reed F emit high frequency spark, you can use.
四、电火花真空检测仪调整及使用
Four, the electric spark vacuum detector adjust and use
先把放电簧插头插入前面插座，然后将电源插头插入220V/50HZ交流电源，接通开关，此时在放电簧端应看到紫色火花。将放电簧移近任何金属物体时，应产生不少于三条火花线，长度不短于20MM。如无火花产生或火花线甚少，或长度甚短，则可调节检测器后面的旋钮，便产生火花，并调节火花至最多最长为止。
The first discharge spring plug into the front socket, and then insert the power plug into 220V/50HZ AC power supply, turn on the switch, the spring end should see purple spark discharge. The discharge reed close to any metal objects, should be not less than three spark line, length not less than 20MM. If there is no spark is generated or spark understood, or length is very short, the knob can adjust the detector behind, will generate sparks, and adjust the spark to the most long.
火花正常后，便可对电子管或其他玻璃真空容器检测其真空程度。
The spark is normal, can be on the tube or other glass vacuum vessel detection of the vacuum degree.
将放电簧对准被测器件，如其真空度相当高时，则紫色火花局限在玻璃壁外。若真空度不高或非真空时，放电簧端的高频电火花（高压）引起容器内气体电离，并产生辉光。
The discharge reed alignment device to be measured, such as vacuum degree is high, the purple spark limited in glass wall. If the vacuum degree is not high or non vacuum, high frequency spark discharge spring end (high pressure) caused by ionized gas container, and produce glow.
五、电火花真空检测仪注意事项
Five, the electric spark vacuum detector matters needing attention
1.本产品供间歇使用（即时开关）如需连续使用（即长时间开着），应需注意，勿使温升超过120℃，以免烧毁线圈。
1 this product for intermittent use (instant switch) for continuous use (i.e., open for a long time), should note, keep the temperature over 120 ℃, so as not to burn the coil.
2.使用时，人体不能靠近或接触高压线圈圆锥形部分，否则有强烈火花电弧跃出会将线圈烧坏。
2 when in use, the human body can not be close to or in contact with the high-voltage coil conical section, or have a strong spark arc will coil burned out.
3.在测玻璃器件时，必须来回移动不要停留，若时间超过五秒钟以上，电火花易将玻璃击穿。
3 in the measurement of glass device must move back and forth, not to stay, if time exceeds five seconds, the glass electric spark breakdown.
4.在检测器使用一段时间后，接触部分可能会烧浊，可用砂布砂光后继续使用。
4 in the detector is used for a period of time, the contact part can burn turbidity, continue to use the available emery cloth sand light.
5.平时不用时应将调节旋钮旋出（即逆时针旋转），使用时把旋钮缓缓旋入（顺时针方向旋转），但应防止接触头短路，将震动线圈烧坏。万一发生接触头短路，（或其他故障）时将内部拆卸出来检修。
5 usually do not have to be the adjusting knob (i.e. a counterclockwise rotation), use the knob slowly screwed (clockwise), but should avoid contact head short circuit, the vibration coil burned. In case of contact head short, (or other fault) will be detached from the maintenance of internal
