Yes, the light meter on the Pentax K1000 works, and it fully tested. Here’s how to check and use the light meter on a Pentax K1000:
Checking the Light Meter:Install the Battery:
- The light meter requires a LR44 1.5V battery or equivalent (e.g., A76 or SR44).
- Open the battery compartment on the bottom of the camera, insert the battery, and ensure it’s correctly oriented.
Turn On the Meter:
- The light meter is activated by advancing the film and partially pressing the shutter button. There’s no separate power switch.
Look Through the Viewfinder:
- You’ll see a needle on the right-hand side. This is the light meter’s indicator.
Meter Reading:
- Adjust the aperture, shutter speed, or ISO dial (if using ASA for film speed) until the needle aligns with the center mark. A centered needle indicates proper exposure.
If the needle doesn’t move:
- Ensure the battery is installed correctly and has sufficient charge.
- Clean the battery contacts if they appear corroded.
- Check if the camera is properly loaded with film or if the back is securely closed, as the meter might not activate otherwise.
If the needle behaves erratically:
- The meter may need calibration or repair, especially if the camera is old or heavily used.
If it’s completely non-functional:
- The light meter circuitry might be damaged. The K1000 is still fully usable without the meter by relying on external light meters or Sunny 16 rules for estimating exposure.
