5.2 VR Assignment

There is one variable resistor (VR1) on the MIC-3716 to adjust the
accurate reference voltage on the MIC-3716. We have provided a test
point (See TP4 in Fig. 5-1) for you to check the reference voltage on
board. Before you start to calibrate A/D and D/A channels, please
adjust VR1 until the reference voltage on TP4 has reached +5.0000 V.
Fig. 5-1 shows the locations of VR1 and TP4.
