Replace your old cap with Timesulin and it will immediately start counting the seconds, starting at one second (00:01) and counting up to an hour. After an hour, the timer mode will switch from MM:SS to HH:MM.
If you wish to check how much insulin is left in your pen, remove Timesulin for less than 8 seconds and the timer will not reset. Lifespan of a Timesulin is 12 months, the screen will start fading and then go blank.
