Check the instrument for general failure
1 . The meter does not display anything, the main reason may be that the battery is not working properly or the contact is not good.
2 . The high-voltage indicator of the megohmmeter is on but the resistance cannot be measured. First check if there is high voltage output, then check if the test line is disconnected, and check if the tested product is in good contact.
3 "1" 或者 "1 OPEN" 时,可能是量程选择不正确或者被测接地极开路、电流辅助特别大。 When the ground resistance test shows "1" or "1 and OPEN" , the range may be incorrectly selected or the ground electrode under test may be open, and the current assistance may be particularly large.
4 . 判别是不是正常。 FC-2G judges whether it is normal. " 显示选择 " 调至 " 电流 " 位,然后将面板测试孔用导线短接, "0.75U" 调在 " 自动 " 位,开启高压,显示屏是否显示 1000 μ A ± 2 ,如果没有则说明 FC-2G 有故障。 First open the rear panel of the meter, adjust the " display selection " at the rear panel to the " current " position, then short the panel test hole with a wire, and adjust "0.75U" to the " automatic " position, turn on the high voltage, and the display shows 1000 μ A ± 2 , if not, the FC-2G is faulty.

The series of meters sold by Jiangsu Jinhu Dongxiang Instrument include: flowmeters, instruments, temperature instruments, pressure instruments, calibration instruments , level instruments, display instruments, transmitter instruments, etc.
