MS7500Main body

System-1
resistivity distribution by constant load

System-2
resistivity distribution by load a increase

System-2
resistivity distribution by load increase and decrease

System-3
Sliding resistance by load increaseAfter it easily sets it , all parameters like the number of sampling , load , movement etc.
are possible the automatic measurement from Windows.

■Probe for load side measurement
The probe of various shape and the material
can be installed.

6 Ranges of 35 mΩ to 3.5 k-Ohm
Measurement current：
7.4 mA～1.5 μA■Probe for fixed side measurement
It corresponds to the narrow contact sidethat can not be done with solder.

■ Dimensions：W320 * H337 * D390（This does't include protrusion.）■ Material：Hard processing aluminum■ Total Weight ：About 14Kg(Without low ohmmeter)■ Current Consumption：100VAC 50/60Hz Max300W■ I / F：USB■ ＯＳ：WindowsXP/Vista<< Attacked measurement program >>System１
The constant load is set while moving the measurement place (fixation),and the contact resistance is measured.
System２
The contact resistance is measured while increasing decreasing the load in thespecified measurement place(movement).
System３
Resistance is measured while making the contact part slide after the measuring load is set.
(It shuttles by the sliding distance)
System４
The contact resistance by the passage of time is measured by a fixed load(follow).

ＣＣＤMonitor
The probe point can be obserbed according to the distance that
doesn't become obstructive.(about 45mm, X16)
Because a standard video is output it is possible to record ina large scale screen and the video recorder etc.(Fixed method)
