sound level meter Frequently Asked Questions

Data Memory

Overview of Data Memory

There are two types of data memory: manual memory and block memory. Data memory can store a unit consisting of simultaneously measured data (LA-1240/1250/1350: Leq/LE/LMAX/LX values, LA-4350: Leq/LE/LMAX/LPK/LX) at the address of each memory.

Notice

• If the built-in battery is completely discharged and the voltage drops, you cannot store the data correctly. Please refer to 'Chapter 2 sound level meter Measurement Preparation / 3.1 Power-On' and charge the built-in battery before use.
• If the backup battery has depleted during storage, the memory data and calendar display will be abnormal. In this case, please perform a memory clear and reset the calendar to restore the state.

Overview of Manual Memory

The manual memory is equipped in the LA-1240/1250/1350/4350 models. In the LA-1250/1350/4350, when the timer measurement is OFF, data can be stored at any address by pressing the panel switch [STORE]. There are up to 300 addresses available, allowing for a maximum of 300 sets of data to be stored. For more details, please refer to '2. Manual Memory Function' later in this chapter.

Overview of Block Memory

Block memory is equipped in the LA-1250/1350/4350. Block memory is the memory used during timer measurements.
Each time a measurement by timer measurement is completed, the measurement data is automatically stored in the block memory. The number of blocks is 10, and the number of addresses per block is 1440. The total number of addresses is 14400, allowing for the storage of up to 14400 sets of continuous measurement data. Manual memory and block memory are switched by pressing the panel switch [TIMER]. At this time, if the timer measurement is OFF, manual memory is selected, and if the timer measurement is ON, block memory is selected. For more details, please refer to "3. Operation of Block Memory" later in this chapter.
