After the startup the tester looks for a connected component to check. Incontinuous mode it will automatically repeat the probing after a short pause.If no component is found for several times the tester will power itself off.In auto-hold mode (signaled by the cursor) the tester runs one probing cycleand waits for a key press or a right turn of the rotary encoder before it willproceed with the next cycle.The cycle delay and automatic power-off for the continuous mode can be adjustedby changing CYCLE_DELAY and CYCLE_MAX in config.h. There's an optionalautomatic power-off for the auto-hold mode (POWER_OFF_TIMEOUT) which is onlyactive during probing cycles.In both modes you can enter a menu with additional functions or power offthe tester.
