Commissioning instructions

1) After welding is completed, restore the default parameters by long pressing the “MENU” key to enter the main menu. Then press the “Range (RNG)” button to enter calibration mode, and press the C (zero) button 5 times in a row. The default value will be loaded: Z0 will change to 76 Z=X.000, and X can be saved from 0-10 by pressing L (HAND)! (At this time, the buzzer does not sound) is the default, long press MENU, and then press (CLR) X to exit Once the default settings are restored, perform an open circuit and reset the short circuit to zero, and the measurement can be completed with an accuracy better than 0.5%

2) Connect the test clip and first reset the open circuit/short circuit calibration compensation. In automatic measurement mode, press the “Zero ZERO” button to scan the frequency and reset the open circuit of the test clip. Press the ZERO (C) button to reset the short circuit of the test clip. If the short circuit is clearly not zero when turned on, it can be reset to short circuit and open circuit. Also, when replacing different testing fixtures, they must be reset to zero

Send 6 calibration resistors with 0.1% precision, 40 ohms, 1k, 3k, 9k, 10k, 100k

Operation Manual
1. Do not measure live components during use, and discharge before measuring capacitance! If the live components are accidentally measured and cannot be used normally, you can replace the front-end protective component 1N4148 by yourself

If the BNC white seat is replaced with a panel BNC seat after taking a picture of the matching chassis!

3. Comes standard with high-quality Hangjia 12V 1.0A adapter! Please try not to replace as much as possible!

4. The program has been burned and soldered back to default before use. No additional firmware and code provided!

5. HC HP is connected to a set of red clips, LC LP is connected to a set of black clips

6. Bridge test frequency 100H 1KHZ 7.8KHZ
