The emission time of the LED 310 may be determined according to the following equation.

[Mathematical Expression]

Irradiation Time = Count (Number_LED│Time_LED) * R_battery

The Irradiation Time corresponds to the emission time of the LED 310, the R_battery corresponds to the variable depending on the remaining amount of the battery 330, and the Count (A | B) corresponds to the counting function for A. Number_LED corresponds to the number of times the LED button 320 is pressed, and Time_LED corresponds to the time interval during which the LED button 320 is repeatedly pressed.

In one embodiment, the light emission time of the LED 310 may be determined differently depending on the value computed by the count function for the number of times the LED button 320 is pressed about the time interval between repeatedly pressing the LED button 320, And may be determined by a variable value concerning the remaining amount of the battery 330. [ For example, when the meter observing apparatus 10 calculates the number of repeatedly pressing the LED button 320 based on a specific time (e.g., 5 seconds, 10 seconds, etc.), the value calculated through the count function is 1 The light emission time of the LED 310 may be determined to be 10 seconds. If the light emission time of the LED 310 is less than 1, the light emission time of the LED 310 may be determined to be 5 seconds. Generally, the light emitting time of the LED 310 may be determined to be shorter as the remaining amount of the battery 330 is smaller. However, the light emitting time of the LED 310 may be set differently depending on the type of the battery 330, Can be set differently.
