| Measurement range | Resolution | Frequency range | Precision |
| 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. | ||||
