10. Remarks
10.1 Output voltage is to be measured using an electrometer with more than 1014 of impedance or an exclusively designed measuring circuit with Ics . Normal testers with around 100MΩ impedance would be insufficient for measurement .
10.2 Upon assembling detectors ,attention is to be paid not to let a soldering flux get inside smoke chambers .If inside of the chambers is contaminated ,cleaning or washing is necessary .
10.3 The output lead wire of a chamber and an input terminal of a circuit must be connected in air to keep the connected point away from the surface of a PC board(usually a teflon pin is used to support the connected point) .Because of the resistance level of paper phenol PC boards , current leakage will occur on to the PC board . This will prevent to read correct outputs .
10.4 The connected point of the lead wire and the input terminal of an FET or an IC must be protected from humidity using a silicon resin or the like so that current leakage from the packages will be minimized .
10.5 Because of the necessity of reading a tiny current put out from the chamber ,this sensor must be electrically shielded to minimize noises from the outside .As the most sensitive part to noises is the connected part of the lead wire and the input the terminal of a circuit ,this part must definitely be shielded .
