Digital multimeter resistor not resetting to zero
Digital Multimeter Resistance Not Zeroing
This is a calibration issue with the multimeter.
It is common for digital multimeters not to return to zero.
It has very little to do with the temperature, humidity and environment.
If it is within 5 jumps, it is generally considered to be qualified.
For example, Festech FT368 multimeter, five ten-thousandths of an inch accuracy.
The resistance of the short-circuit of the meter needle between -0.02~0.02 ohm is qualified.
What you said above may be a calibration problem when the meter is shipped from the factory.
How to make the resistance of digital multimeter not 0 when shorted?
Hold down the HOLD+RANGE key for 10 seconds at the same time to get to 0.
Digital multimeters are available as portable units for basic troubleshooting, or as bench-placed units, some with resolutions up to seven or eight digits.
A digital multimeter is an electronic instrument to be used in electrical measurements. It can have many special functions, but the main function is the measurement of voltage, resistance and current. Digital multi-meters, as modern multi-purpose electronic measuring instruments, are mainly used in the field of physical, electrical and electronic measurements.
Digital multi-meter in terms of safety features
1,Fuse current input protection.
2,Use of high energy fuse off (600 volts or higher).
3, High voltage protection in resistance mode (500 volts or higher).
4, Voltage transient protection (6000 volts or higher).
5,Safety designed test leads, safety handles, etc..
6, Independent safety certification.
