FT series dc to ac solar inverter 12v24v
When measuring the current, if the actual current value exceeds the range, it will generally only cause the fuse in the multimeter to blow, and no other damage will be caused. Therefore, when measuring voltage parameters, if you do not know the approximate range of the measured voltage, you should first set the measurement gear to the highest gear, and then change the gear to measure the value to obtain a more accurate value.
If the voltage value to be measured is far beyond the maximum range that the multimeter can measure, a high-resistance measurement lead should be provided. Such as detecting the second anode high voltage and focusing high voltage of black and white color TV.
The DC voltage upper limit range of most digital multimeters is 1000V, so when measuring DC voltage, the maximum voltage value is below 1000V, which generally will not damage the multimeter.
If it exceeds 1000V, it is very likely to cause damage to the multimeter. However, the upper limit of the measurable voltage may be different for different digital multimeters. If the measured voltage exceeds the range, the method of reducing the resistance of the resistor can be used to measure it.
In addition, when measuring the DC high voltage of 40O ~ 1000V, the test leads must be in good contact with the measurement place, and there should be no jitter. Otherwise, in addition to causing damage to the multimeter and making the measurement inaccurate, the multimeter can be used in serious cases. show.
