Item description
Usage Tips
If you use a magnifier with high brightness, please reduce the aperture to f22 for metering and keep the developer fresh. See the sticker on the back for exposure compensation.
The “power switch” is a cyclic type. Press to turn on and press it again to turn off. Don't use excessive force to avoid damage to the corresponding components.
The “metering knob” has a limited point. After turning to the limit point, don't continue to rotate hard to avoid damage to the corresponding components.
The “Metering Point” sticker is a special light-transmissive material. Do not remove the sticker from the parts, otherwise the metering value to be out of alignment.
Except for battery replacement and calibration, do not disassemble or modify the board. The internal components are precise and please operate properly.
During the metering and calibration operations, there shall be no obstructions above the “metering point” and no reflective objects on the sides.
The meter is not waterproof. Don't immerse the meter in the liquid.
More operation indication are elaborated on the English Manual.
How to use:
1. please adjust the size of the projection screen of the magnifier to the size of the photo to be printed, and confirm that the focus is clear and the size is correct.
2. Adjust the aperture of the magnifier lens, and the project image is as the as size as the photo you want.
3. Turn off the other light sources and turn on the light meter, and place the metering “metering point” on the brightest part of the projected image. Keep the position of the metering point not moving and observe the "exposure indication" status. If the yellow indicator is on, it indicates that the exposure is insufficient. Please turn the “metering knob” clockwise until the green indicator is on. If the red indicator is on, it indicates overexposure. Please turn the “metering knob” counterclockwise until the green indicator is on. Please adjust the process carefully and turn the “metering knob” slowly.
4. When the green indicator is on, please check the “exposure time” corresponding to “pointer”, the unit is “second”.
5. Adjust the amplifier timer to the time just measured, and to magnify the photo paper for the corresponding time.
