8. Power the Combo Tester X3 using the included
power supply.
WIRING THE COMBO TESTER X3 TO AN ACCESS
CONTROL SYSTEM
The Combo Tester X3 may be connected to an Access
Control System to grant access when both a valid
proximity badge is read and PASS test results are
achieved at the tester. Figure 8 shows an example
when using a turnstile.
*NOTE: The Access Control System must have a time
delay feature in order to achieve the configuration
described above. Set the Access Control System’s
relay to remain active for a few seconds when a valid
proximity badge is accepted. The relay will need to
remain active long enough for an operator to perform a
test on the Combo Tester X3. The access control device
will only unlock when it receives an active signal from
both the Access Control System and Combo Tester X3.
Operation
1. A circling light around the test switch indicates when
the Combo Tester X3 is on standby and ready to
perform a test.

2. While wearing a wrist strap and/or ESD footwear,
plug the wrist cord into its corresponding jack
located on the face of the Combo Tester X3. Place
one foot on each foot plate.
3. To begin the test, use your finger to bridge the test
switch’s inner and outer contacts. The blue standby
LED will become solid to indicate that the test has
been initiated. Hold your finger down until the test
results are displayed.
If your finger is removed too early, the tester’s LEDs
will blink three times to indicate that the test was not
completed. DO NOT touch any other metal while
performing your test as this will affect your results.
