三、電火花真空檢測機工作原理
Three, the electric spark vacuum detector working principle
接通電源後由L1與CD產生振鈴，在CD的觸點之間發生電火花現象，激勵C及L2組成的回路串聯諧振，經L3感應產生高頻電壓，然後由放電簧F放出高頻電火花，即可使用。
After the power is switched on by L1 and CD for generating a ringing, electric spark phenomenon occurred 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、電火花真空檢測機調整及使用
Four, the electric spark vacuum detector adjust and use
先把放電簧插頭插入前麵插座，然後將電源插頭插入220V/50HZ交流電源，接通開關，此時在放電簧端應看到紫色火花。將放電簧移近任何金屬物體時，應產生不少於三條火花線，長度不短於20MM。如無火花產生或火花線甚少，或長度甚短，則可調節檢測器後麵的旋鈕，便產生火花，並調節火花至最多最長為止。
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.
火花正常後，便可對電子管或其他玻璃真空容器檢測其真空程度。
The spark is normal, can be on the tube or other glass vacuum vessel detection of the vacuum degree.
將放電簧對準被測器件，如其真空度相當高時，則紫色火花局限在玻璃壁外。若真空度不高或非真空時，放電簧端的高頻電火花（高壓）引起容器內氣體電離，並產生輝光。
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、電火花真空檢測機註意事項
Five, the electric spark vacuum detector matters needing attention
1.本產品供間歇使用（即時開關）如需連續使用（即長時間開著），應需註意，勿使溫升超過120℃，以免燒毀線圈。
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.使用時，人體不能靠近或接觸高壓線圈圓錐形部分，否則有強烈火花電弧躍出會將線圈燒壞。
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.在測玻璃器件時，必須來回移動不要停留，若時間超過五秒鐘以上，電火花易將玻璃擊穿。
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.在檢測器使用一段時間後，接觸部分可能會燒濁，可用砂佈砂光後繼續使用。
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.平時不用時應將調節旋鈕旋出（即逆時針旋轉），使用時把旋鈕緩緩旋入（順時針方向旋轉），但應防止接觸頭短路，將震動線圈燒壞。萬一發生接觸頭短路，（或其他故障）時將內部拆卸出來檢修。
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
