Web3 Fluke Corporation ABCs of DMMs A DMM’s ability to measure ac voltage can be limited by the frequency of the signal. Most DMMs can accurately measure ac voltages with frequencies from 50 Hz to 500 Hz, but a DMM’s ac measurement bandwidth may be hundreds of kilohertz wide. Such a meter may read a higher value 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 …

WebThe way most DMMs measure resistance is by pushing a small amount of current through the part and measuring the voltage across it (due to Ohms law) using an ADC. When the resistance is too high, the voltage drop is simply too small for the ADC to pick up and it would just be recognized as infinite resistance or an open circuit.

WebApr 2, 2013 · DMMs typically employ the constant-current method to measure resistance, which sources a constant current (I SOUR ) to the device under test (DUT) and measures the voltage (V MEAS ). Resistance (RDUT) is then calculated and displayed using the known current and measured voltage (R DUT = V MEAS /I SOUR ). WebDec 27, 2006 · Significantly, Fluke Corp .'s latest Model 8845A and Model 8846A DMM s (digital multimeters) can make the same kind of measurements with two test leads. Fluke's special split-terminal jacks let you perform equivalent 4-wire measurements using only two leads instead of four. You do that using an optional TL2X4W test lead accessory.

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.
