WebDMMs measure down to high as 300 MΩ (300,000,000 ohms). Infinite resistance (open circuit) is read as “OL” on the Fluke meter display, and means the resistance is greater than the meter can measure. Resistance measurements must be made with the circuit power off—otherwise, the meter or circuit could be damaged. Some DMMs provide protection WebJun 2, 2024 · When measuring resistance What does OL on the DMM indicate? Most DMMs measure down to 0.1 Ω, and some measure as high as 300 MΩ (300,000,000 ohms). Infinite resistance (open circuit) is read as “OL” on the Fluke meter display, and means the resistance is greater than the meter can measure. chicken swap coloradoWebFeb 20, 2024 · DMMs measure current by using a shunt resister.

"WebFirst, the major components of test instruments (e.g., voltage references, input dividers, current shunts) can simply shift over time. This shifting is minor and usually harmless if you keep a good calibration schedule, and this shifting is typically what calibration finds and corrects. But, suppose you drop a current clamp — hard.
