A customer’s pentaxk1000 with a light meter needle that pegs up at all times. After a quick diagnosis the cause was found to be a faulty galvanometer. After a parts swap the meter is performing just as it should. Tip: The k1000 light meter has no on/off switch, but does turn off automatically when light drops below EV 2 at ISO 100. So when not in use it’s a good idea to keep a lens cap on your camera and maybe even a cover on the eyelens to prevent constant draw on the battery.
