Digital Variable resistor Noise Checker

Narrow margin (△TR) measurement for all resistance value of rheostat


●Contact check function built-in

●All resistance value (△TR) can be measured by

   deviation value [±99.9%]

●Possible to measure of “intensive contact resistance

   ” (Rc)[19.9%]

●The “NOISE VALUE” can be measured by the AC/DC mode.

●AC noise (ENR)(Peak hold)

●DC noise (CRV)(Peak hold)

●The measurement of Rc and noise can select ON/OFF


The Outline

 AX-901 can measures not only “ALL RESISTANCE VALUE” (Delta R) of variable resistor but also “LUMPED CONTACT RESISTANCE” (Rc) when wiper is stationary.

 And also AX-901 can measures to change element (DC/AC) in contact resistance

continuously generated by movement wiper. (AC noise is called “ENR” / DC noise is called “CRV”)

 The measuring display part can display two items of Delta TR[99.9%] and by switching Rc/ENR/CRV[19.9%].
