4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
-
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty crimps, recessed pins, pin contact contamination, improper wire gauge, and stress-extruded wire.This option may be purchased with any new HVX tester, or added as an upgrade to any of your existing HVX testers.

MAX31855 J-Type Thermocouple Arduino Shield
SEN-30004-J03
-
Four channel MAX31855 digital thermocouple Arduino Shield. Two versions of this shield are avaliable for each thermocouple type: either 'Ch 0-3' (CS pins use Uno/Mega IO pins 7-10) or 'Ch 4-7' (CS pins use Uno/Mega IO pins 3-6), with the only difference being which set of zero-ohm resistors are populated on the board. This allows use of other SPI devices that may be 'hard coded' to specific digital pins on the Arduino, or simply stacking one of each type together to get a total of eight thermocouple channels on one Arduino. The MAX31855J supports a measured temperature range of -210C-1200C with known thermal characteristics and output resolution of 0.25C. Included thermocouple connectors are type-specific to provide proper material continuity as close to the IC as possible. The SEN-30004 is interfaced via 3 or 4-wire SPI and a high-speed level shifter is included to allow the board to plug directly into an Arduino Uno or Mega
