Open-Collector Output

•When the SIGNAL OUT switch is set to ALL:

The output transistor switches on when the results of the shoe and wrist strap test are OK. When making alternating shoe/wrist strap tests, the type of test to be conducted next is indicated by the blinking symbol on the LCD and the blinking LED.

•When the SIGNAL OUT switch is set to WRIST:

The output transistor is on when the result of a wrist strap test is OK.

•When the SIGNAL OUT switch is set to SHOES:

The output transistor is on when the result of a shoe test is OK.

Shoe and Wrist Strap (ALL) Setting

•If you attempt to test while the wrist strap LED is blinking and without having the wrist strap connected to the Shoes and Wrist Strap Tester 747, “Err.2” appears on the LCD. In this case, connect the wrist strap cable to the front panel connector and test again.

•Conducting a wrist strap test followed immediately by a shoe test allows the shoe test to be performed while the wrist strap remains connected to the front panel when testing one shoe only.

Important Note:

Using the 3M™ Software 747DLS with the 3M™ Shoes and Wrist Strap Tester 747 requires the following action: When testing a wrist strap and two shoes, the wrist strap ground cord must be disconnected from the Shoes and Wrist Strap Tester 747 after testing the wrist strap to perform the shoes test.

•If more than ten seconds elapse between a shoe test and a wrist strap test, the automatic power-off function clears the last test results. In this case, repeat the last test.
