Page 5: Introduction
The 229-2 is designed only for measuring leakage current of appliances oper- ating from 120 or 240 power line circuits. The current ranges of the 229-2 have an insertion impedance of 1500 ohms, resistive with a parallel capacitance of 0.15 F. -
Page 6: Why Measure Leakage Current
The 229-2 is battery operated and completely insulated for user protection. Solid-state circuitry permits a current sensitivity to be as high as 300 A full scale (minor divisions of 5 A). Two voltage ranges of 0-150V AC and 0- 300V AC provide a convenient means of measuring the open circuit voltage (between the accessible parts and ground) to determine whether leakage current need be measured. -

Input Resistance On Voltage Ranges 500K on the 150V VAC range 1MEG on the 300V VAC range Accuracy @ 60 Hz, Sine Wave: 3% on voltage and current ranges. Frequency Response: Approximates Dalziel’s Percentile 50 (Current Ranges) Threshold of Perception Curve. Reference Conditions: 23°C 1°C, 30% to 60% relative humidity. -
Page 8: Operation
Model 229-2 in a safe and proper manner. Safety Precautions The Model 229-2 is designed to be used only by personnel qualified to recog- nize shock hazards and trained in the safety precautions required to avoid possible injury. Refer to SHOCK HAZARD definition which is located on page 3 of this manual. -
Page 9: Operating Instructions
De-energize the equipment to be tested. Turn the function selector switch to the SHORT TEST position. Connect Model 229-2 Leakage Current Tester, as shown in the figure 2. Disconnect protective grounding connection (3rd wire) -
Page 10: Maintenance
The Model 229-2 will withstand 300V AC (50/60 Hz) on short test for approxi- mately 10 seconds. If the pointer is deflected into the green area, the leakage current may be measured more accurately by turning the selector switch clockwise until best reading is obtained. -
Page 11: Calibration
