�WARNING and PRECAUTIONS • Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. • Inspect the INSP-3 wiring inspection tester before every use. Do not use any damaged part. • Never ground yourself when taking measurements. Do not touch exposed circuit elements or test probe tips. • Do not operate the instrument in an explosive atmosphere.
Unpacking and Inspection Your shipping carton should include: 1 INSP-3 Wiring Inspection Tester 1 Power Cord 1 9V Alkaline Battery (Installed) 1 Users Manual 1 Carrying Case If any of the items are damaged or missing, return the complete package to the place of purchase for an exchange. INTRODUCTION The INSP-3, wiring inspector is a rugged tester designed to verify building wiring compliance to electrical code, especially voltage drop under load.
• Meter detects faulty wiring in need of repair without removing outlets cover plates, or panel covers: • Faulty splices and connections • Incorrect wiring • Undersized wiring • Faulty GFCIs, • Faulty or incorrectly wired AFCIs • Incorrect line voltage • Poor ground quality • User selectable 10,15 and 20 amps loads to verify performance of the electrical system • Incorrect wiring or voltage drop test failure is clearly indicated by flashing screen • Will not trip circuit breakers or blow fuses during the te
Operation A High Quality Adaptor should be used when testing 2 wire outlets. Ground impedance and polarity is not tested on 2 wire outlets. 1. Push GFCI TEST push button or AFCI TEST push button before plugging the INSP-3 to a GFCI or AFCI circuit outlet to be tested. 2. Plug the INSP-3 wiring inspection tester into an energized 120V wall outlet using the power cord provided. Refer to Fig.1 3. The unit will turn itself ON and display the test results. 4. Push the desired Set Load push button.
Line 2: shows the polarity status Line 3: The “SET LOAD” switch is set for a test drawing 15 amps. At 15 amps of current draw, the voltage at the outlet would drop by 4.2%. Since 4.2% is lower than the NEC recommendation of a maximum of 5% drop, it would not be flashing. Line 4: shows that 1.1% of the voltage drop is on the hot conductor while 3.1% is on the neutral conductor. Line 5: shows that the voltage at the outlet would drop to 116.4 volts with a 15 amp load applied.
the wiring resistance would limit the current to approximately 424 Amps. Line 5: shows that if the hot and ground conductors were to be shorted at the outlet, the wiring resistance would limit the current to approximately 850 Amps. NOTE: Unit turns on automatically when plugged in. Push and release Power/Select push button to toggle between screens. What the Readings Mean A) Voltage under load: This is the actual voltage available if a steady load of 10, 15 or 20 amps is applied to the line.
loose connection or if the wiring run is too long or has too small a gauge wire for the length of the run. The electrical code states that “. . . where the maximum voltage drop on both feeders and branch circuits to the farthest outlet does not exceed 5 percent, will provide reasonably efficiency of operation” (Sec.
and high technology electronics are reliant on a good quality equipment ground for proper operation. A typical rule of thumb is ground resistance in most cases should be less than 2 ohms. Loose connection, splices or too small of a ground conductor can cause high impedance. If less than .05 ohms is indicated on a medium or long wire run, check the test outlet for a short between neutral and ground. D) Polarity Test – This test checks for typical wiring errors involving three wire outlets.
smaller than 14 gauge wire and not longer than 4 feet. Large power disturbances or spikes may cause erratic readings. SPECIFICATION Load: Constant 0, 10,15 or 20 AMP simulation regardless of line voltage Operating Voltage: 95-140V AC Power: 9V Alkaline Battery Fuse: ½ Amp, 125V. Not user replaceable. GFI Trip: 6.0 mA nominal to trip GFI, 30 mA to trip RCD AFCI Trip: Up to 8, 120 Amp pulses within ½ second period Operating Temperature: 0°C to 50°C ( 32°F to 120°F) Accuracy: +/- 2%, +/- 2 digits.
3. Review the operating instructions for possible mistakes in operating procedure. Except for the replacement of the battery, repair of the meter should be performed only by a Factory Authorized Service Center or by other qualified instrument service personnel. The front panel and case can be cleaned with a mild solution of detergent and water. Apply sparingly with a soft cloth and allow to dry completely before using. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.
