Periodic Performance Checks
Do a self check test or a test plug threshold (sensitivity) test periodically to verify
the Product works properly. A self check test verifies proper operation of most of
the circuits, A test plug threshold test verifies the proper sensitivity and insulation
of the Product.
Do a self check test each time before you use the Product. Do a test plug
threshold test at least weekly or if the Product has been subjected to severe
mechanical stress.
If the Product fails the self check or test plug threshold test, do not
use the Product. Contact Fluke to repair or verify the integrity of the
Product.
Self Check Test
If the Product fails a step below, do not continue with the test.
To do a self check test:
1. Clean and dry the entire housing and make sure the housing does not have
any cracks. Moisture, dirt, and other foreign matter reduces the insulating
properties of the plastic surface.
2. Grasp the handle with your bare hand and push the trigger.
3. If the green LED does not illuminate or is very dim, replace the battery. If the
green LED does not illuminate after you replace the battery, the Product fails
the test.
4. Push and hold the trigger with one hand and use your other hand to touch the
probe tip and the check contact (see Figure 3). You may need to wet the
fingers that touch the probe tip and check contact to make the red LED flash.
The Product passes this step when the red LED flashes and the green LED
turns off.
5. Continue to hold the trigger and remove your hand from the probe tip and
the check contact. As long as you hold the trigger, the red LED flashes when
the Product works properly and passes the test.
