What is the ScopeCorder's Accuracy Specifications in Terms of DMM Digits?
Resources:
In terms of display resolution, the 720210 and 701250 modules (12-bit) are equivalent to a 4 digit DMM. The 701262 module (16-bit) is equivalent to a 5 digit DMM. However, in terms of DC accuracy, the 720210 and 701250 modules are equivalent to a 3 digit DMM, and the 701262 module is equivalent to a 4 digit DMM.
See the attached screen shot for an example of the DMM style monitor function display mode.
- The 720210’s DC accuracy is 0.5% of 10 div
- A CH1 full scale of +/-50.00mV means 100mV span
- 0.5% of 100mV is 0.5mV
- But 720210’s display digit is 50.00mV
- Therefore, the DC accuracy of 720210 is equivalent to 3 digits.
