Sound level meter - Frequently Asked Questions

■Calendar function settings

The LA-1240/1250/1350/4350 models have a built-in calendar function (clock). This calendar function allows for the display of the current time, the start time of measurement (when displaying measurement results or recalling memory), and other information on the LCD display, as well as printer output.

■ How to reset the date

The date may not be set correctly immediately after purchase. After charging the built-in battery, we recommend resetting the date (year/month/day/hour/minute/second) using the following steps.

• Turn on the power while pressing the panel switch [Lp/Leq (DATE)]. The date (**:**:**) will flash on the LCD screen.
• Press the panel switch [LEVEL (▲・▼)] to switch the value you want to set.
• The setting items (flashing) switch in the following order by pressing the panel switch [FAST/SLOW (NEXT)]: year → month → day → hour → minute → second. The setting items are shown in order.
• After completing the setup, press the [START (ENTER)] panel switch. The date data will be reset and the sound level meter will start up.
• The built-in clock has an error of ±1 minute per month under a temperature of 25°C.
• This sound level meter has separate clocks for the calendar and for measuring elapsed time. Therefore, there may be a discrepancy between the measurement time and the calendar time, but this is not a malfunction. Please be aware of this.
