Test Procedure for the CCRGEVB 2.0 Evaluation Board
Setup:
1. Connect a DC power source across PWR1 and PWR2. Polarity does not matter because of
the bridge rectifier on the board.
2. Connect a voltmeter across TP4 and TP7 to measure voltage across R3 (1 mV = 1 mA). This
will effectively provide a measurement of the current through R3, because

2. Connect a voltmeter across TP4 and TP7 to measure voltage across R3 (1 mV = 1 mA). This
will effectively provide a measurement of the current through R3, because
R3 is a 1 Ω resistor.
3. Remove any jumpers that may be on the board.
Circuit 1: Do NOT exceed 70 mA:
1. Put jumpers on JP1, JP4, JP5, JP6, and JP9.
2. Apply an input voltage of 15
Circuit 1: Do NOT exceed 70 mA:
1. Put jumpers on JP1, JP4, JP5, JP6, and JP9.
2. Apply an input voltage of 15
Vdc across PWR1 and PWR2 and flip the switch to the “On”
position.
3. Verify that LED D5 is on. Measure voltage across R3 to get current. Current should be 17 to
25 mA.
4. Flip
3. Verify that LED D5 is on. Measure voltage across R3 to get current. Current should be 17 to
