Modelfor Low Resistance Measurement

Realized low measuring current■ 200mA (0.01mΩ ～ 99.9mΩ)By high accurate amplifier installed , Model 7310A canmeasure very low current of 200mA and make ensure
protection of probe by mitigation burden of measuringprobe's top.
■ Measuring range 1mΩ ～ 10kΩ(switching display of ％ & Absolute value)
Hi-speed & Hi-accurate measurement of resistancedeviation between 1m Ω～10 k Ω and digital display.
■ Free setting of Contact Check operation of OFF,7310A■ Display of 16 kinds of Contact Error
When contact error, the error point canconfirm by display of Cord display.

CE 123456789A
BBefore,After.

Can select the following 4 ways.
1）No Contact Check2）Contact check before/ after of measurement3）Contact check before measurement4）Contact check after measurement

Cd★(Contact error at contact resistance over 30Ω)

EF*******************************■ Power save measurement system*
Have Power Save Function which open circuit
at only the time of measurement.
Thus can be minimized measuring error by upwardof temperature etc.
Measuring way■ Full time Contact Check function
FAST mode : Measurement in one time
(Measuring Wayeform check)
SLOW mode : Masurement in two time
Always check all terminal contacting conditions（average),changing polarity ofwhile measuring and when detecting abnormal Output
measuring voltage ,measure
Contact Error.
Thermoelectromotive cancel.
■ Multi-Scaling system
Can set Display Limit（ Full scale display）＊ At below 9.9mΩ of setting Force Value,mode is
at ± 9.99 ％ ± 19.99 ％ ± 99.9％ freely
fixed as SLOW.
