ICL7107-DigitAL LED AMMETER  - Ammeter is a great addition to any Laboratory Power Supply as it will measure the current consumption and help you determine if there are any problems with the circuit that you are building or testing. This amper meter is capable of measuring the current consumption up to 10A with selected 100mA, 10mA and 1mA accuracy. ….(circuit design added 11/08)
ICL7107-DigitAL LED VOLTMETER  - This digital voltmeter is ideal to use for measuring the output voltage of your DC power supply. It includes a 3.5-digit LED display with a negative voltage indicator. It measures DC voltages from 0 to 199.9V with a resolution of 0.1V. ….(electronic schematic added 11/08)
