10 mm Snap Adapters

The 19322 Full-Time Continuous Monitor includes an 

interchangeable 10 mm park snap and 10 mm banana 

jack adapter for operators who use wrist cords with 

10 mm terminations. Use the park snap's knurled rim 

to unscrew the 4 mm park snap from the monitor and 

install the 10 mm park snap to the monitor. Plug the 10 

mm operator jack adapter into the monitor's operator 

jack.

19322 Full-Time Continuous Monitor

Operation

1. Fit the wristband snugly onto the wrist.
2. Snap the wrist cord to the wristband.
3.

4.

Plug the wrist cord into the operator jack. The green

 

operator LED will illuminate. This indicates that the

 

operator is properly grounded.

If this does not happen, examine the wrist cord for

 

continuity or damage and the wristband to ensure

 

that it fits securely. If you have dry skin, apply an

 

approved dissipative hand lotion such as 

Menda

 

Reztore® ESD Hand Lotion.

5. When leaving the workstation, first touch the

monitor's park switch or park snap. The monitor's

audible alarm will disable for approximately 8

seconds. Use this time to disconnect the wrist cord

from the wristband and attach it to the park snap

without sounding a false alarm.

6. Upon returning to the workstation and disconnecting

the wrist cord from the park snap, the monitor will

provide approximately 8 seconds for the operator to

reconnect the wrist cord to a worn wristband before

sounding the monitor's alarm.
