480B Tirohanga Hiko-Teitei
♦ Tirohanga
Mena ka hono atu ki te kaitirotiro waiariki whakauru, ka taea e te mita hiko kawenga te whakarato i nga raraunga ahu-maha o te ngaohiko, o naianei, te mana me te pāmahana i te wa kotahi mo te tātari matawhānui, penei i te hononga i waenga i te pāmahana me te kaha o nga waahanga, nga tikanga whakawera i raro i nga ngaohiko rereke. i roto i te tātari rauemi whakawera, etc.
Kua oti i te Hangarau Dianyang te mahi whakatikatika, a ka taea e ia te whakarato i te 480B High-precision Power Meter me te Dingyang DC Load Analyzer.
Ko te hoahoa o te 480B e tango ana i te 32-bit teitei te tukatuka tere tere me te kaitahuri AD 24-bit-rua, me nga ahuatanga o te tino tika, te awhe hihiri whanui, me te hanganga kiato me te maamaa. Ko te reanga hou-whakatupuranga mata pa ki tātari hiko mamati. Ko tana RS232/485, USB, Ethernet me etahi atu hononga ka taea te whakatutuki i nga hiahia rereke o nga kaiwhakamahi mo te whakamatautau korero.
♦ Nga tohu hangarau taketake:
| Tohu Hangarau | Tawhā Hangarau |
| Aratuku | DC: (0.5 - 1) KHz |
| Aratau whakauru | Ko te whakauru maangi ka whakamahia mo te ngaohiko me te naianei |
| Whakaatu whakahōu | Ka taea te whakarite i te huringa whakahou i waenga i te 0.1 me te 5 hēkona |
| Te tātari raina | Te auau tapahi o 500Hz |
| Tahuri A/D | Ko te wa tauira mo te 70μS, 24 bit; ka tautokohia te tauira tukutahi o te ngaohiko me te naianei |
| Te aukati whakauru | Ko te impedance tāuru ngaohiko e pā ana ki te 2MΩ, te impedance tāuru o nāianei e pā ana ki 0.5Ω i te taumata iti me te 4MΩ i te taumata teitei. Ko te aukati whakauru o te kapeka whakauru tohu o te pūoko o waho ka huri ki te ngaohiko whakauru. Hei tauira, ina he 10V te ngaohiko whakauru, he 100kΩ te impedance whakauru; a, ka 2V te ngaohiko whakauru, ka tata te 20kΩ te impedance whakauru. |
| Kore tikanga whakatika | Ka huri ki te kore ina huri te awhe ine, ka huri ranei te aratau ine. |
| Aratau ine | RMS Pono, tikanga ngaohiko, AC, DC |
| Te paunga hiko katoa | <10VA |
| Mahinga hiko mahi | AC: 100V - 240V 45-440Hz; DC: 100V - 300V |
| Atanga whakawhitiwhiti | USB (paerewa), RS-232/485 (paerewa), Itarangi (he kōwhiringa) |
