Insert the test leads into the "COM" and "VΩ" holes, turn the knob to the desired range in "Ω", and connect the test leads to the metal parts at both ends of the resistor.
Opaziti:
1. If the measured resistance value exceeds the maximum value of the selected range, the over-range "1" will be displayed, and a higher range should be selected. For the resistance greater than 1MΩ or higher, it will take several seconds for the reading to stabilize. This is normal.
2. When not well connected, such as open circuit, the meter displays "1".
3. Ko preverjate impedanco preskušane linije, se prepričajte, da odstranite vse napajalnike v preskušani liniji in izpraznite vse kondenzatorje. Če so v testirani liniji napajalniki in elementi za shranjevanje energije, bo to vplivalo na pravilnost preskusa impedance linije.
4. The 200MΩ gear of the multimeter has 10 characters in short circuit. When measuring a resistance, these 10 characters should be subtracted from the measurement reading. For example, when measuring a resistance, it is displayed as 101.0, and 10 characters should be subtracted from 101.0. The actual resistance value of the measured component is 100.0 or 100MΩ.
5. Med merjenjem se lahko dotaknete upora z rokami, vendar se z rokami ne dotikajte obeh koncev upora hkrati - človeško telo je prevodnik z velikim, a omejenim uporom.
