Connect the opposite end of the test lead into the yellow banana jack labeled “WRIST STRAP” on the Combo Tester. Toggle the switch to the “WRIST STRAP” position. TECHNICAL BULLETIN PPE-5034.E Figure 2. Connecting the test lead from banana jack “E” on the Calibration Unit to the WRIST STRAP banana jack on the Combo Tester 2. Connect the second test lead to the red 675K banana jack labeled “A” on the Calibration Unit. Touch the opposite end of the test lead to test plate on the Combo Tester and press down to activate the test. Be sure not to touch the banana plug or test plate with your skin. 3. Observe the response from the Combo Tester. The alarm should sound, and the LOW LED should illuminate red. 4. Repeat the procedure for test points B (825K), C (35M) and D (40M). The expected test results can be found in the following table. Test Point Resistance Value Test Output A 675K FAIL LOW B 825K PASS C 35M PASS D 40M FAIL HIGH

Charleswater 99090 Tester Calibration Unit Description The Charleswater 99090 Tester Calibration Unit is designed to simplify the process of calibrating the Charleswater 99000 and 99004 Combo Wrist Strap / Footwear Tester. The calibration unit allows the user to quickly and easily verify whether the tester is operating within specifications. The Calibration Unit is a passive device, and requires no power source. It is manufactured with industry accepted test ranges for both wrist straps and foot grounders. The wrist strap pass range is set at 825k- 35M, and the foot ground test range is set at 825k - 35M. The Calibration Unit is supplied calibrated to NIST traceable standards. Packaging 1 Tester Calibration Unit 2 Test Leads 1 Certificate of Calibration Operation WRIST STRAP TEST CIRCUIT Step 1: Connect one of the test leads to common point banana jack “E” on the Calibration Unit. Connect the opposite end of test lead to the banana jack labeled “WRIST CORD” located on the face of the Combo Wrist Strap / Footwear Tester. Ensure that the rocker switch on the tester is set to WRIST CORD. Step 2: Connect the second test lead to the 675k jack labeled “A” on Calibration Unit. Touch the opposite end of test lead to tester’s test plate and press down with enough pressure to activate the test circuit. Observe the LED’s for the proper response as indicated below. Be sure to hold the cord at an insulated point, so that the resistance value is not affected by the body. Resistance Value Test Output - LED Red jack “A” - 675k: Red (FAIL LO) Green jack “B” - 825k: Green (PASS) Green jack “C” - 35M: Green (PASS) Yellow jack “D” - 40M: Red (FAIL HI) Step 3: Repeat the procedure testing across jacks B, C, and D on the Calibration Unit. The different resistance ranges should give the display shown above. If the tester does not meet calibration specifications, contact Charleswater for calibration.
