417/5000  

Test type ac resistance test

 

 

Test method four-wire measurement

 

 

Ac current frequency 1KHZ + / - 0.1KHZ

 

 

The voltage measurement is divided into two levels

 

Dc 0 ~ 5.000V, resolution 1 mV, accuracy + / - (0.2% RDG +5dgt).

 

Dc 5.00v ~ 20.00 v, resolution 10mV, accuracy + / - (0.2% RDG +5dgt)

 

The measurement of internal resistance is divided into two levels

 

Low range: 3 m Ω ~ 300.0 m Ω test current of 10 ma

 

Ω high range: 300 m ~ 3000 m Ω test current 1 ma

 

 

Internal resistance calibration potentiometer calibration (additional purchase of standard resistance box)

 

 

Test alarm can be set with the failure of internal resistance alarm or qualified alarm

 

 

Jig form aviation plug, can connect jig box or test line
