Low-cost 1000:1 AC/DC dual-use high-voltage attenuation probe. Maximum measurement voltage: DC±40kV, AC±28kV (50/60Hz only). Input impedance up to 1000MΩ. Please specify the use of a meter with an input impedance of 10MΩ. Specific parameters are as follows:

Input impedance: 1000MΩ
Attenuation ratio: 1000:1
Test voltage (max): DC   0~ ± 40kV, AC   1~ 28kV (50/60Hz), polarity positive/negative can be measured
Accuracy: DC: ± 2% to 20kV, ± 3% to 40kV
AC: -5% to -15% (1~28KV; 50/60Hz)
Temperature coefficient: ≦ 200ppm/℃
Load current (max): ≦ 40μA (at 40kV DC)
Power consumption (heat generation) (max): ≦ 1.6 watt
Operating temperature: 0℃ ~ +50℃
Operating humidity: 20~75%RH
Specified connection: 10MΩ; input impedance DMM
Meter output indication x1000, i.e.,   1000V→1V, 10kV→10V
Weight: 260g
Dimensions: Φ80*340 mm
Note: The selected meter must have an accuracy within ±0.5% in addition to the specified input impedance of 10MΩ, otherwise it will seriously affect the attenuation ratio.
