in the following situations.

Turning the Screen Light On and Off
To reduce battery consumption, you can turn off the screen light or adjust the brightness between
two levels.
Further, the screen light can be turned off automatically when there is no user interaction with the
instrument for a given period.
Note
If the screen light is turned on in a dark location, white spots may appear on the screen.
This is due to the material characteristics of the light guide of the screen and has no effect on the
performance of the instrument.
Communication Resistance
This instrument has an built-in 250 Ω communication resistor. When communicating with a
transmitter, you do not need to prepare a separate external resistor.
Power Supply Priority
When both batteries and USB power supply are available, priority can be given to either source.
When the priority power supply cannot be used, a switch is made to the other part supply.
