Operation
The LC102 AUTO-Z power supply can be used for various applications beyond capacitor leakage testing. It is capable of high-potential testing and testing resistances up to 1 gigohm. The power supply is portable, battery-operated, and provides a regulated, well-filtered, current-limited DC output adjustable in 0.1 volt steps from 1.0 to 999.9 volts, with current outputs from 2 mA to 200 mA depending on the voltage selected.
The LC102 can be used as a remote voltage source, making it suitable for applications requiring DC supply away from AC power lines. It is useful in design, research, or production-line testing, and can be controlled via computer with optional IEEE 488 or RS232 Bus Interface accessories.
The LC102 is equipped with a STOP TESTING alarm that activates if the fuse opens, protection circuits trigger, or test leads are connected to a charged circuit. If the alarm activates, testing should be stopped immediately, and the capacitor being tested should be discharged using a 10k ohm 1 watt resistor. The test lead fuse should be replaced if blown, or voltage should be removed from the test lead connection point before resuming testing.
The power supply can also be used for testing zener diodes by applying a voltage higher than the zener’s rated voltage through a current-limiting resistor, and monitoring the voltage drop across the diode with an external voltmeter. It is also suitable for powering low-powered devices like small radios and remote controls, and for line tracing in cables by identifying one pair of conductors out of a large cable using its battery operation.
The LC102’s current-limiting feature protects it from damage due to excessive power draw, and its digital current readout aids in troubleshooting.
Troubleshooting & Error Codes
Refer to the PDF for details.
Safety & Warnings
The manual includes the following safety warnings and precautions:
1. If the STOP TESTING alarm is activated, immediately stop all testing with the LC102.
2. The alarm is triggered by either the fuse opening, the protection circuits opening, or connecting the test leads to a charged circuit.
3. The alarm provides alerts through an audible buzzer and a flashing LED.
4. If the STOP TESTING alarm activates, follow these steps:
– Stop all testing with the LC102.
– Carefully discharge the capacitor being tested by connecting a 10k ohm 1 watt resistor across the terminals.
– Replace the test lead fuse if blown, or remove the voltage from the point the test leads are connected to.
– Resume testing.
5. A current-limiting resistor is necessary for most tests to protect the component from damage due to excessive power. The resistor value depends on the current rating of the device being tested. Use 1 watt (or larger) resistors for ample power dissipation when testing shorted parts.
