When you look at the meter in the meter box, at 10V of DC it is 0,2,4,6,8,10.
If you are measuring 5V, the meter bar will show between 4 and 6. 3.3V is displayed between 2 and 4. If the DC is measured above 10V, the metering channel must be set to 50. When set to 50, look at 0,10,20,30,40,50. When measuring 12V, the meter bar will be displayed between 10 and 20. P4 connector; Molex connector; Mini-Molex connectors should be measured in the same way as above. Specified DCVs must also be output. It is important that any wire is used to measure the depth of the meter jerk pin to the depth of the power supply. It is not dangerous to humans because it is only up to 12V DC, but it can be reduced if the wire pins are attached.
