Megger 235303 Appliance Tester DESCRIPTION 
The Biddle Tool and Appliance Tester model 235303 combines, in one portable unit, the three most frequently specified electrical safety tests for tools and appliances. In conformance to the latest UL and ANSI test requirements, the instrument performs tests of ground continuity, leakage current and electrical insulation. It also checks the nameplate current rating of the device.
Biddle 235303 APPLICATIONS
Poorly maintained electrical tools can become a safety hazard and cause injury to personnel. Testing electrical tools on a regular basis is not only safe practice against costly repairs, but may even reduce liability. Applications for this handy instrument include inplant OSHA safety surveys and production line, tool room and repair shop safety checks.
Ground Continuity Test
To check the integrity of the ground circuit between tool and plug, the instrument applies a 25-ampere test current to the ground circuit. If the ground circuit resistance exceeds the 0.10 W failure threshold, a safety interlock prevents further testing. A bypass switch is provided to allow testing of two-wire and double-insulated devices.
Insulation Breakdown (HiPot) Tester
This test measures current through intsulation at high voltage to detect weak spots in the insulation that may cause failure in the future. Test voltage up to 3,000 volts ac may be applied, with the leakage current trip level adjustable from 0.3 to 12 mA by a front-panel control knob. Visual and audible alarms alert the operator to insulation failure.
235303 Operational Check
The Megger Tool and Appliance Tester (235303) also provides an operational check to verify the nameplate current rating of the tool and to determine if maintenance is required. Measurements up to 15 amperes are indicated.
