LQ-9101
User Manual
Suitable for 1Ω to 10MΩ, are used when the measured impedance is not too low.
The second-line table pens are used for road detection analysis and are more convenient than other
methods. The following conditions should be taken into account in the detection or measurement of
independent components.
Due to the large contact resistance of the second-hand table pen and the large infuence of the size of
the force, the contact area and the degree of cleanliness, the subjective perception is that the reading is
unstable. Therefore, when the measured impedance is low, besides paying attention to the infuence of the
additional inductance, it is necessary to adopt Measures of contact resistance stability, specific methods,
can use a trowel to trim the nib, trim into a sharp cone or prismatic shape, for reference only.
When the measured impedance is not too low, the above-mentioned low-resistance infuencing factors do
not stand out.
When the impedance to be measured is relatively high, follow the notes in 4.5.2.
