Healing

The Healing tab lets you check the tubes and restore digits that have lost their glow.

A digit that stays dark for months can lose part of its glow (cathode poisoning). The regular cleaning cycle prevents this. Healing is for digits that are already affected: the clock lights them for many hours over several weeks.

Digit Inspection

Tap a digit from 0 to 9 in Select Digit and all tubes show it, so you can compare how evenly the digits glow. Tap it again, or tap Deactivate, to return to the clock.

Per-Tube Inspection

There is one card for each tube, counted from the right: Digit Tube 1 is the rightmost tube. On Puri 6 the tubes are Digit 1, Digit 2, Colon 3, Digit 4, Digit 5, Colon 6, Digit 7 and Digit 8; on Puri 4 Digit 1, Digit 2, Colon 3, Digit 4 and Digit 5.

In each tube's card, select the digits that need healing (for a separator tube, its dots 0 and 1). Reset All clears every selection and stops healing.

Healing Execution

While healing runs, each selected tube shows its selected digits in turn, changing every second; the other tubes keep showing the time. Healing runs for 30 days and then stops by itself. It continues after a power cut or restart. With Night Only, the clock shows the time normally during the day.
