NOTE: DO NOT TOUCH ANY OTHER METAL WHILE
PERFORMING TEST.
Figure 12. Testing of wrist strap grounding assemblies
4. Lighting of the green “PASS” LED indicates that the wrist
strap and ground cord assemblies are functioning properly.
5. If either red “FAIL LO” or “FAIL HI” LEDs light and the
audible indicator sounds, the wrist strap wearer should
check the wrist strap assembly immediately.
TESTING FOOT GROUNDING DEVICES
When testing conductive shoes or heel straps, test each
foot separately to ensure proper operation and complete
protection.
1. Press rocker switch toward “FOOTPLATE”.
2. Place one foot on the baseplate. If the floor is conductive,
lift the foot you are not testing off of the floor during this test.
Make sure there is no ground cord plugged into the “WRIST
CORD” jack.
3. Press the test button so that the unit activates. Hold down
for 2-3 seconds.

Calibration
The models 99000 and 99004 are calibrated to factory
standards. We recommend that calibration is performed
annually to ensure that the Tester is operating within limits.
Due to its dual circuit design both test circuits of the Combo
Tester must be calibrated individually.
Charleswater offers a calibration unit that is specifically
designed to simplify the calibration procedure. This unit
comes calibrated to factory standards. For additional
information on the 99090 , ask for Technical Bulletin
PPE-5034.E .
