Individual (I) or Global (G).The winning combination of microwave and PIRMore dealers are choosing Honeywell’s DUAL TEC sensors for this very reason. The winning combination of microwave and PIR technologies enable the sensors to actually distinguish between real intruders and other environmental conditions. For an alarm to occur with a DUAL TEC, both the PIR and the microwave sensor must “confirm” each other and detect an intruder within the defined protection area. The result? Optimum performance and minimal false alarms. Honeywell offers a wide range of DUAL TECs—including sensors that provide up to 100 lbs.Choose from hardwired, wireless or V-Plex polling loop versions for the ultimate installation flexibility.

Anti-Masking: Detects intentional and accidental blocking of the PIR optics. Walk Test Mode: Determines the coverage pattern and functionality for both the PIR and microwave channels, usually through LED indicators.http://ersanteknoloji.com/images/canadian-firearms-study-manual.pdf PIR Sensitivity Adjustment: Selectable option to change the PIR process sensitivity, usually through a DIP switch or jumper link. Vertical Adjustment: Capability to adjust the vertical PIR detector position relative to the optics, usually through a vertical shift in the PCB. Usually used to adjust range at different mounting heights, or accurately set the coverage pattern for different lenses or mirrors. Horizontal Adjustment: Capability to shift the PIR zones left or right by a few degrees. Usually used to locate potential false alarm sources, such as a heating vent between zones, or to aim the optics in a particular direction, such as a hallway. PIR Supervision: Automatic self-test of microwave channel for proper operation. Recommended Mounting Height: Suggested height to mount processor for optimal performance. Usually important for pet immune applications. Operating Temperature: Temperature range at which the sensor can be expected to provide adequate protection. UL certification may have a narrower range.

Sonda vermelha em dois outros soquetes. O conector 10ADC e usado quando e necessario medir a forca da corrente de 200mA a 10A. O conector V?mA e usado para todas as outras medicoes - tensao, corrente de ate 200mA, resistencia, continuidade. Quase todo segundo proprietario de um multimetro recomenda substitui-los por outros melhores. E verdade que o custo deles pode ser comparavel ao custo do proprio testador. Em casos extremos, eles podem ser aprimorados reforcando-se os locais de flexao dos fios e isolando as pontas das sondas. Alguns eletricistas ate dao preferencia a eles, considerando-os mais confiaveis. No entanto, os consumidores comuns sao menos convenientes de usar devido ao grande erro da escala de medicao. Alem disso, ao trabalhar com um multimetro indicador, voce deve definitivamente adivinhar a polaridade dos contatos. No digital, se a conexao com os polos nao estiver correta, as leituras serao simplesmente exibidas com um sinal de menos. Este e o modo padrao de operacao, que nao estraga o multimetro. Para fazer isso, coloque o interruptor no multimetro na posicao apropriada. Se essa for a voltagem em casa (voltagem alternada), coloque o interruptor na posicao ACV. Insira as pontas de prova nos conectores COM e V?mA. Se um deles for instalado por engano no terminal 10ADC, ocorrera um curto-circuito durante a medicao de tensao. A polaridade das sondas neste caso nao desempenha absolutamente nenhum papel. Nao e necessario tocar zero com uma sonda preta e passar com uma vermelha.Para medir a tensao, as pontas de prova devem ser conectadas paralelamente ao circuito medido, enquanto com os dedos segure apenas a parte isolada da ponta de prova para que voce nao fique sob tensao. Se o visor mostrar o valor da tensao com um sinal de menos, significa que voce inverteu a polaridade. Se voce comecar a medir a tensao quando o interruptor DCA estiver ligado, ou seja, medir a corrente, podera criar facilmente um curto-circuito diretamente em suas maos! Com o isolamento inadequado das sondas e sua quebra, isso se protegera, em certa medida, contra choques eletricos. Se a bateria comecar a ficar fraca, o multimetro comecara a ficar sem Deus. Em vez de 220V, todos os 300 ou 100 Volts podem aparecer na tomada. Portanto, se as leituras do dispositivo comecarem a surpreende-lo bastante, verifique primeiro a energia. O sinal indireto de descarga da bateria pode causar alteracoes caoticas no visor, mesmo quando as sondas nao estao conectadas ao objeto medido. O interruptor deve estar na posicao - DCA. Ou seja, voce precisa interromper o circuito e conectar as sondas ao espaco formado. Voce pode fazer isso em qualquer lugar conveniente (no comeco, meio, fim da cadeia). Mas, se pelo contrario, o multimetro falhara. Se voce medir a resistencia em algum dispositivo ou fio que esteja funcionando, e recomendavel desconectar a energia dele (mesmo da bateria). Assim, os dados de medicao serao mais precisos. Se durante a medicao no visor voce exibir o valor “1, OL” - isso significa que o dispositivo esta sinalizando sobrecarga e a chave precisa ser colocada em uma faixa de medicao maior. Se “0” for exibido, vice-versa, reduza a escala de medicao. Na maioria das vezes, um multimetro no modo de resistencia e usado durante o trabalho de reparo, para verificar a operacionalidade dos eletrodomesticos, a saude dos enrolamentos e a ausencia de um circuito no circuito. O nivel de resistencia nao e mais importante aqui, e importante entender o que ha com o circuito em si - seja inteiro ou nao. Como o uso frequente pode danifica-los, especialmente no ponto em que o fio entra no tubo da sonda. Antes de cada medicao, verifique se nao ha voltagem na area em que voce conectara as pontas de prova para discagem; caso contrario, podera queimar o dispositivo ou criar um curto-circuito. E voce pode usa-lo com seguranca e produtividade durante os trabalhos de reparo. DT-838 e seus analogos M-830 - M-838; Os principais parametros e modos de medicao para todos os modelos desses dispositivos sao os mesmos - todos eles sao capazes de determinar tensao, corrente e resistencia. Instrumentos com medicao da frequencia ou parametros de transistores tambem raramente sao necessarios para medicoes, a menos que voce esteja fazendo isso profissionalmente. E se considerar que eles praticamente nao podem ser mantidos, trabalhe com o dispositivo com cuidado, tendo estudado as instrucoes e possuindo pelo menos conhecimento basico de medicoes eletricas. Para isso, as sondas incluidas nas tomadas “COM” e “V?mA” sao conectadas em serie a carga. Coloque o interruptor de limite na posicao desejada. A medicao pelo dispositivo de uma forca de corrente acima de 10A nao e fornecida. Para esses fins, use um modelo de pinca amperimetrica, como o Mastech MY-68. Para isso, as sondas sao conectadas aos soquetes “COM” e “V?mA” e a chave seleciona o tipo de tensao DCV - constante, ACV - variavel e o limite necessario.O medidor DT-830B permite controlar este parametro dentro de 200 Ohms - 2MOhm com uma precisao de 1 M-838 sao analogos completos dos dispositivos descritos acima. Alem disso, o M 838 esta equipado com um termopar para medir temperaturas na faixa de 20 a 300 graus C. Dispositivos de comutacao massiva foram substituidos por multimetros compactos, que possuem muitas funcoes uteis. Nesse sentido, muitos eletricistas novatos enfrentam algumas dificuldades no desenvolvimento de novos dispositivos. No artigo, consideraremos como usar o multimetro DT830B. Usando esta ferramenta universal, voce pode determinar rapidamente os parametros e caracteristicas eletricas necessarios. No entanto, o DT830B esta equipado com uma balanca com uma ampla gama de medicoes, equipado com sondas de medicao e tem a capacidade de auto-diagnosticar. Portanto, o dispositivo e frequentemente usado por engenheiros eletricos profissionais, fornecendo resultados de medicao precisos. O multimetro e alimentado por baterias CRONA de 9 volts. Em geral, o modelo e uma opcao de orcamento e e vendido no mercado a um preco de ate 400 rublos. Todos os elementos do circuito sao colocados em um estojo pequeno, na frente do qual o interruptor principal esta instalado no centro. E o principal elemento de controle e cobre aproximadamente 20 posicoes. Todos os dados de medicao recebidos sao exibidos em um display digital de cristal liquido. No entanto, a alta sensibilidade do multimetro fornece bons resultados de medicao e, em termos de indicadores basicos, fica apenas um pouco atras dos dispositivos mais caros. A magnitude da tensao CA esta na faixa de 200 a 750 V. O visor de cristal liquido possui uma capacidade de 3,5, o que e um bom indicador. O limite maximo de resistencia que pode ser medido e de 200 kOhm. O dispositivo opera normalmente a uma temperatura de 0 a 40 graus. O dispositivo em si e muito leve e pesa apenas 137 gramas. Comparado aos modelos profissionais, o numero de funcoes e um pouco limitado. No entanto, se tomarmos outros testadores domesticos para comparacao, aqui o multimetro digital DT830B e notavelmente superior a eles, gracas a indicadores de alarme, uma escala de medicao estendida, um testador de diodos e outras opcoes adicionais. Eles sao feitos na forma de barras de metal com alcas revestidas com isolamento. A principal funcao das sondas e garantir o contato entre a area medida e o proprio dispositivo. O conector para a sonda e selecionado de acordo com o parametro que voce deseja medir. Esta incluida uma sonda com fios pretos, que permanece nessa posicao durante qualquer manipulacao.
