Mga tampok
1. The insulation resistance tester has a variety of voltage output options (2500V/5000V/10000V), and the measurement resistance range can reach 0 ~ 400GΩ.
2. Ang halaga ng insulation resistance ay ipinapakita nang sabay-sabay sa dalawang paraan. Ang paggamit ng mga analog pointer ay madaling maobserbahan ang pagkakaiba-iba ng paglaban ng pagkakabukod, at ang paggamit ng digital na display ay maaaring tumpak na makuha ang mga resulta ng pagsukat.
3. Gumamit ng naka-embed na pang-industriya na single-chip microcomputer at real-time na operating software system. Mataas na antas ng automation, malakas na anti-interference na kakayahan, ang instrumento ay maaaring awtomatikong i-save ang mga resulta ng pagsubok, nang walang manu-manong interbensyon.
4. Friendly na interface ng operasyon, ang iba't ibang mga resulta ng pagsukat ay may anti-power failure function, at 19 na mga resulta ng pagsukat ay maaaring patuloy na maimbak.
5. Kapag ang instrumento ay bumubuo ng mataas na presyon, magkakaroon ng isang mabilis na output ng tunog at kaukulang display.
6. Parehong AC at DC, nilagyan ng rechargeable na baterya at AC adapter.
7. Ang insulation resistance detector ay gumagamit ng portable na disenyo, na maginhawa para sa field operation.
8. High-voltage short-circuit current ≥1mA. It is an ideal testing instrument for measuring insulation resistance of transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
