Cropico DO4001 Digital Microhmmeter
Includes: Cropico DO4001, non rechargeable batteries, lead set LS06-P, operating handbook and calibration certificate.
The Cropico DO4001 portable digital milliohmmeter is a practical instrument for low resistance measurement, ideal for use in the workshop, field or test facilities. This milliohmmeter is of rugged construction contained in a sturdy plastic case.
The Cropico 4001 employs the four terminal resistance measurement method to eliminate the effect of lead resistance errors. The measured values are displayed on a 4-digit LCD display; an overflow of the selected range is also indicated.
Simple push button selection of the range required plus and auto range feature ensures the ohmmeters may be easily used by unskilled personnel, error and status warnings are illuminated when appropriate. The utmost care has been used to ensure that the ohmmeters will withstand accidental mains voltage applied to the measuring terminals, but it is not recommended that voltage should be applied.
Both the DO4000 and the DO4001 models have similar functionality and measurement capabilities, except the DO4001 also includes automatic temperature compensation and temperature measurement capabilities.
