Measuring Using Sensors (SENSOR)

You can use this function to measure the output of a current sensor or other type of sensor
that converts its measured values into voltages, to convert the voltages into the original
measured values, and to display the converted values.
Before you perform measurement, you need to configure unit, conversion, and other
settings. See "SENSOR Mode Input, Display, and Unit Settings" in section .6, "Setup
Function."
) Turn the function switch to the "mV" position.
2) Press SHIFT+SELECT to switch to DC SENSOR mode.
To switch to AC SENSOR mode, press SELECT again.
The input voltage appears in the subdisplay. In the main display, the value converted
using the settings configured in "SENSOR Mode Input, Display, and Unit Settings" in
section .6 appears.
