The Mark-10 WTT-ESM Motorized Wire Terminal Tester is a precision solution for wire terminal testing applications up to 200 lb. The WTT-ESM-STD Standard (Basic System for destructive testing) is a basic system designed for destructive testing to determine the maximum force a crimped on connector will hold. The Mark-10 WTT-ESM-ADV Advanced (Advanced System with Closed Loop Control) is specifically designed for meeting ASTM test standards that require a test sample to maintain a specific load for a set interval (typically 1 minute). The closed loop control function will automatically adjust the load to stay constant during the test. Performs Test Procedures According to UL486A and SAE/USCAR-21. Standard USB and RS232 output allow operators to transfer data to a PC or data collection system.
