0.00V~50.00V | 0.01V | 45 ~ 200Hz sine | 2%+5 |
Input resistance: about 1MΩ
Measurement rate: 2 times/s . |
Range | Measurement range | Resolution | Precision | Remarks |
20Ω | 0.10Ω~19.99Ω | 0.01Ω | 5%+5 | 0.2 Ω error is added when the resistance is less than 2Ω.
RH and RS are 500ΩRk corrected data. |
200Ω | 20.0Ω~199.9Ω | 0.1Ω | ||
2000Ω | 200Ω~1999Ω | 1Ω | ||
Output features: test open circuit voltage UM, the maximum is around 50Vpp, square wave
Test the short circuit current IM, the maximum is around 3mApp, but IM☓(RH +RE)< UM Measurement time: typical 2 seconds. RH MAX: (4K Ω+100RE) or 50KΩ (whichever is lower). RS MAX: (4K Ω+100RE) or 50KΩ (whichever is lower). Additional error at RH MAX or RS MAX: 3%+10. Series interference voltage: 16·2/3Hz, 50Hz, 60Hz, 400Hz and DC 3V (20Ω range does not include DC). Additional error at 3V series interference voltage: 5%+10. |
