Digital insulation resistance tester AKZC30
One, the function and the characteristic of
1, good load characteristic. The instrument has an internal stable DC 500V / 1000V / 2500V / 5000V high voltage generator.
2, the measurement is not subject to zero. The use of simple, convenient.
3, timing accuracy. At the same time generate high voltage and measuring instruments in the start time, so read 15S and 60S, 10min insulation resistance value is accurate.
4, large capacity (large short-circuit current). The absorption current and charging current decreased rapidly, the measured value of insulation resistance and reliable.
5, strong anti-interference ability. The instrument adopts SCM as the core, to eliminate the error caused by the magnetic coupling; another instrument internal take filter circuit, eliminates the charged device and the measured capacitance coupling between devices. Therefore, the measurement accuracy.
6, improve safety measures. Automatic stop high-voltage output after the end of the measurement, and long beep take notice.

数字式绝缘电阻测试仪AKZC30

一、功能及特点

1、负载特性好。本仪器内部有一个稳定的直流500V／1000V／2500V／5000V高压发生器。
2、测量时不须调零。使用简单、方便。
3、计时准确。仪器在产生高压并进行测量的同时开始计时，所以读取的15S和60S、10min绝缘电阻值准确。
4、容量大（短路电流大）。使吸收电流和充电电流迅速减少，测得可靠的绝缘电阻值。
5、抗干扰能力强。由于仪器采用单片机为核心，消除了磁耦合引起的误差；再有仪器内部采取滤波电路，消除了带电设备和被测设备之间的电容耦合。因而测量比较准确。
6、完善的安全措施。测量结束后自动停止高压输出，并长时间蜂鸣提起注意。
