AIC-1000標準配置

主機、接地線、使用說明書

 

操作說明：

１、連接機器的接地線

２、選擇確定ＰＯＬＡＲＩＴＹ在+或-,確定測定正、負離子

３、直立機器，旋鈕在OFF，按紐的開關放在STANDBY，然後然後旋鈕至19.99×10n;

４、熱機1分鐘，當數字不變化時（基本在一個中心變化），按下按鈕到RE-ZERO，並且保持3-5秒；

５、當顯示的數字在-0.02-0.02時，就已經穩定；如果不穩定，需要重新調零；６、測量時，按紐的開關放在MEASURE就開始測量；

７、根據顯示的數值的大小，旋鈕可以跟蹤旋至不同的量程范圍上； 如果在測量過程顯示數字1，則應調節到大一量程范圍檔位；

 

註意事項：

1、測量時，要保持空氣的相對靜止，不流動，同時測量人員應遠離一個手臂左右；

2、電池電壓低於7.5V，應該更換電池，待機情況下（STANDBY），電池使用時間約為10小時；測量情況下（MEASURE），電池使用時間約為2小時，否則，測量的結果會產生很大誤差；

3、不要聯續開機測定；

4、讀數要取出現的數值范圍的中間讀數。

Production Description:
The Air Ion Counter is a handheld meter designed to measure ion density-- the number of ions per cubic centimeter (ions/cc) in air. It measures this number separately for positive and negative ions (+ and - ions are usually present simultaneously). This instrument is a true ion density meter, based on a "Gerdien Tube" design, and it contains a fan which pulls air through the meter at a calibrated rate. The standard model measures up to 2 million ions/cc (for comparison, outdoor air typically has 100 to 1000 ions/cc, both + and -). The 2 million range is sufficient for almost all situations except for measuring very close to electric ionizers or strong radioactive sources. For these applications, models with ranges of 20 million and 200 million ions/cc are also available. (Range can be specified on the checkout page; all three ranges are $470.) 

Output Description:
A plug (included) can be inserted in the left side of the meter to monitor the output, which is a slowly-changing analog voltage. This is a stereo phone plug identical to the plug on small headphones in which the ground has been cut. An output of +1.999 volts (or -1.999) represents full-scale of the meter, regardless of which RANGE is seleced. 

Option Description:
The rechargeable battery system (Lithium Ion battery at full charge runs six hours at maximum drain, recharges in three hours, has 500-1000 charge cycles of life). Both the AC adapter and the charger for the rechargeable system operate from 110 to 250 VAC (50 to 60 Hz), and either can power the meter directly. If the AC adapter is ordered, it disconnects the internal battery when plugged in, and it does not recharge the batteries.

Air Ion Counter Operation:

Air is sucked in at the top (photo), is measured, and exits at the bottom. The display shows the ion count within 2 seconds and it continues to display the ion density in the air, showing any changes within 2 seconds after they occur. The POLARITY switch determines whether + or - ion density is displayed. (In the photo, negative ion density is being measured.) To conserve power, the switch on the right side can be flipped to STANDBY; this turns the fan off and stops the measurement. A rotary offset control fine-tunes the internal amplifier so the display reads zero if no ions are present (or whenever the meter is on STANDBY). No adjustment of this is needed unless the temperature changes significantly. An analog output jack is present, which is useful for long-term automated monitoring. The meter uses a standard 9 volt battery, but an AC adapter and a rechargeable battery system are two options.

 

Please note: solids do not produce ions unless there is an energy source (such as radioactivity, high voltage or heat above about 600° C). For example, neither tourmaline nor "diodes" produce any ions at room temperature unless radioactive material has been added. However, liquids evaporating can produce ions.

 

1. When ordering the 20 million ions/cc model, multiply range and resolution by 10. For the 200 million model, multiply by 100.

2. The unpredictable nature of ion self-destruction in the air just outside the meter makes more accurate measurement impossible (some ions are lost as air is redirected, positive and negative ions neutralize each other spontaneously, etc.)
