2. Other Devices
Consider a circuit of a specialized tester for checking the operation of an aquarium-heater thermostat. It consists of a 9V transistor battery, a 100-ohm resistor, a 1.

3. Appliance Leakage Tester
Leakage current can be measured with an instrument such as the RCA WT-540A ac leakage tester. This instrument has no switches, dials, or other operating controls, its black test lead, which is terminated in a clip, is connected to a ground point.

4. Rechargeable - Battery Tester
The rechargeable-battery tester corrects this condition by deep-discharging the battery several times and recharging to restore its original capacity.

6. Tvi Filter For Appliances Employing Universal Motors
Considering the reward of interference-free reception, this inexpensive, easy-to-build tester should prove a most worthwhile project. The filter readily passes 60 Hz ac but offers resistance to the passage of the high-frequency ripple generated by the motor commutator and brushes.

7. Diode / Triac Tester
This tester enables the appliance repairman to efficiently troubleshoot such speed-control assemblies without removing the components from the circuit.

8. Home Manicure Kit
Do not use a 110V series light continuity tester or damage to low-voltage components will occur. If the switch or deck is defective, the entire deck and switch assembly may be easily replaced by loosening two screws holding the transformer and two screws holding the connector-pin board.

9. Table - Range
Now using a continuity tester, attach one lead to one prong of the cord and touch the other lead to exposed metal parts such as: the stove body, top deck, and front panel.

10. Electric Heaters
Use a continuity tester, VOM or wattmeter when making any adjustment to the thermostat. To adjust for room temperature, slide the temperature-control knob slowly to the right until the circuit is complete.
