MIN MAX Recording Accuracy and Response Time

Specified accuracy of the measurement function ±12 digits in dc for changes >200 ms in duration (±40 digits in ac). Typical 100 ms response to 80%.

Example 1: This would mean ±1.2° when recording temperature.

Example 2: This would mean ±12 μA when recording μA or ±12A if used with a dc amp probe (with a mV input).
