2.3 Operating Instructions
Do not touch the device or appliance under test with power applied until
voltage and leakage current measurements have been made and found to be
within applicable requirements. Obviously, during the test the requisite elec-
trical safety has not yet been established. Therefore when going through the
measurement procedure, do not touch test leads or device under test while
power is applied.
NOTE: Leakage current alone is not conclusive evidence of a shock hazard.
For safe operation, the open circuit voltage between the same two points
must not exceed 30V rms.
1. Turn the function selector switch to the BATT. TEST position. The pointer
will deflect to the right-hand side of the dial if the battery is OK, as indi-
cated on the lower most arc.
2. With the appropriate voltage range of the Instrument, test for proper line
voltage being applied to the device under test.
3. De-energize the equipment to be tested.
4. Turn the function selector switch to the SHORT TEST position.
5. Connect Model 229-2 Leakage Current Tester, as shown in the figure 2.
Figure 2. Model 229-2, Leakage Current Testing Diagram
6. Energize the equipment to be tested. If the pointer is deflected to the red
area (or above) on the second arc from the bottom, immediately turn off
power. The leakage current is greater than 10 mA and a “short” in the
device is probable.
