19557 is an ideal, newly developed multifunction relay tester adopting monolithic computer technology. It is
composed of auto synchronized digital millisecond timer, logic controlling unit, multifunction digital display, high precision digit collection and processing unit, current-voltage output unit, overload and over range protection unit. Test process is automatic for improved efficiency. The tester has a built in printer for printing the results.

 

Feature

• Micro-computer controlled: Self test function and error reporting
• Audio Visual warning and automatic cut-off for overload and over range
• Highly intelligent: One key tests and prints complete parameters of universal relay
• LED display screen
