Data storage

500 groups, press MENU to keep data, HOLD symbol display, press MENU again to cancel

Data review

Long press the MENU button to enter the data reference mode,  MR symbol display, press MENU again to exit

Data is full

Data full function: “FULL” symbol display

Switch display mode

Long press the POWER button to switch between the test display mode and the conversion ratio display mode

No signal indication

When the host does not receive the transmit signal, it prompts “no signal”

Automatic shut-down

About 15 minutes after power on, the meter will automatically shut down

Battery voltage

When the battery voltage drops to 3.5V, the low-power indicator lights to remind you to replace the battery

When the battery voltage drops to 5.2V, the battery voltage is low symbol to remind to replace the battery
