then displays the test result. The instrument
Telaris 0100-ELECTROcheck works with a limit

for the trip time. The contact voltage and trip time
determined are checked to see if they meet the
limit values and are directly displayed as result
(10) or (6), together with the
As additional reference a green LED is illuminat-
ed behind the LCD to indicate that the test has
been completed successfully, the red LED indi-
