UT131 Palm Size Multimeter
Notes:
*.Before measuring resistance, switch off the power supply of the circuit, and fully discharge all
capacitors.
*. If the resistance when shorted is more than 0.5Ω, please check if test leads are loosened or
damaged.
*.If the resistor is open or over the range, the “OL” symbol will be displayed on the screen.
*.When measuring low resistance, the test leads will produce 0.1Ω~0.2Ω measurement error. To
obtain accurate measurement, the measured value should subtract the value displayed when
two test leads are shorted.
*. When measuring high resistance above 1MΩ, it is normal to take a few seconds to steady the
readings. In order to quickly obtain steady data, use short test wires to measure high
resistance.
