DC double arm bridge QJ
PIC-(DC double arm bridge QJ)
Fixture: Compliant with GB3048 standard, used in conjunction with electric bridge
Features:
1. The instrument can achieve 0.1 μ Measure the resistance of Ω -2.5M Ω.
2. The measurement results are automatically saved and can be queried at any time, with the ability to save 200 sets of data.
3. Provide calibration function, which can use standard resistors for digital calibration to ensure that the measured display value is consistent with the standard value. Eliminate the concern of using traditional resistance testing equipment that may cause deviations due to electronic device aging and cannot be corrected.
4. There are ten levels of automatic shifting between 1m Ω and 1M Ω, and the appropriate gear is automatically selected for measurement without the need for manual selection.
5. 0.01mA-1A automatic switching of 6 levels of current. Provide constant current source and voltage measurement functions.
6. Full range automatic zero calibration, forward and reverse measurement, measurement direction can be directly set in the menu.
7. Multiple modes of manual and automatic measurement. The automatic measurement mode can automatically switch to appropriate current measurement based on the size of the resistance. The manual measurement mode measures according to the set current.
8. The function of measuring the length of the entire coil of wires allows for the measurement of cable length without disassembling the coil.
9. 12864 LCD display, touch buttons, Chinese menu parameter settings (English panel provided for export), intelligent measurement, only press the measurement button during measurement.
10. The instrument has an automatic discharge protection function to prevent static electricity from testers and test samples from damaging the instrument equipment during wiring.
