Summary of Contents for REVENI LABS Camera Tester

  • Page 1 3. Peel off screen protector sheet 4. Find the two M5x12mm set screws in the bag of parts 5. Install the 200mm rods into the Camera Tester, aligning the flats on the rods with where the set screws will meet it 6.
  • Page 2 9. Plug in the sensor head and put it on the vertical rods 10. Plug in the 12V wall adapter and connect it to the Camera Tester (ONLY USE THE INCLUDED WALL ADAPTER!) Assembled Unit...
  • Page 3 The Reveni Labs Camera Tester can be set up in several ways depending on the user’s preference and the type of cameras being tested. The Camera Tester can be used in a vertical or horizontal orientation. Orientation is detected at power-up and the screen and buttons are rotated accordingly.
  • Page 4 There are two sensor heads available. The 35mm sensor head is standard and is included with every Camera Tester. The 35mm head is used to test all leaf shutters, 35mm focal plane curtain shutters, and can be used to test medium format focal plane shutters as well, but only in the central area covered by the 35mm frame size.
  • Page 5 Reflective Laser Sensor Head A sensor head which uses three lasers to do curtain analysis on shutters with no opening back is now available. This sensor is uses in curtain mode only, and only works on LTM (39mm thread mount) horizontal shutter cameras such as Barnack Leicas and other similar cameras. User Interface The faceplate of the device has 5 buttons, a power switch, and an LCD display.
  • Page 6 PC Printout The Camera Tester can sent data to a PC via USB. It does this by emulating a keyboard and works with Mac, PC or Linux. The computer’s keyboard should be set to US QWERTY layout otherwise some text characters will come through oddly.
  • Page 7 Testing Modes Curtain Shutter Curtain testing is done without a lens attached to the camera. These tests are done with the LED panel at full brightness. DIRECTION: select the curtain travel direction so the distance between detectors can be correctly determined. FORMAT: Select the appropriate frame size so that the curtain travel time can be correctly calculated.
  • Page 8 This screen also shows the flash contact Figure 5 - Curtain Fractional Speed Results delay following the full opening of the first curtain. Flash contact testing requires the PC port or hot shoe to be connected to the Camera Tester via the appropriate cable.
  • Page 9 Middle Time and Left/Right Relative Exposure Error Pressing the LEFT or RIGHT button again will change to a middle time view with the left and right times replaced with the relative EV error with respect to the middle time Figure 6 - Curtain Shutter Middle Time and Left/Right EV Variation Curtain Times and Velocities Pressing the LEFT or RIGHT buttons again will change to a view which depicts the front of the...
  • Page 10 Average Mode Results In average mode, the average, min and max for each sensor will be displayed in milliseconds. The quantity of averages will be counted at the top. The max variation is the largest variation in exposure on one of the sensors. Figure 9 - Curtain Time Averages Leaf Shutter Leaf Shutter mode is used to test any in-lens...
  • Page 11 The Camera Tester performs a high speed analog analysis of the shutter performance, and determines the opening time, fully open time, closing time, and effective shutter speed. Leaf Results Topen: Shutter opening time (from initial detection to 95% maximum brightness)
  • Page 12 the exposure curve will appear irregular if the sensor was misaligned or there is a major mechanical issue with the shutter. Press the DOWN button to view the curve again. Leaf Exposure This mode will permit testing of auto- exposure cameras which use a leaf shutter. It will measure both the brightness at the film plane (to determine aperture) and measure shutter speed to determine the...
  • Page 13 Curtain Exposure This mode will operate similarly to the leaf exposure mode, except making some alterations to compensate for the curtain travelling past the sensor instead of the centrally-opening leaf shutter. These tests must be done with a lens attached, with the sensor placed at the camera’s film plane.
  • Page 14 Reflective Shutter Test This mode allows for testing shutters which do not have through-body access for the sensor head to sit at the film gate. This mode is effective for shutter speeds up to 1/1000. The mirrored card included with the Camera Tester is placed at the film gate by inserting into the camera in place of film.
  • Page 15 Light Meter This mode sets the light panel to the selected reflected EV equivalent, so that reflective meters (both handheld and in-camera) can be tested against it. The LED panel should fill the field of view of the light meter, so when testing non-TTL camera meters, be sure to place the metering cell as close to the panel as possible.
  • Page 16 The measured aperture will be continuously read out on the display. The Camera Tester will automatically adjust the sensor sensitivity range as the measured brightness varies. T: This is the measured aperture displayed as a T-stop. T-stops are like F-...
  • Page 17 Once started, the process takes a few minutes to complete. If calibration is accidentally activated, power off the Camera Tester to stop it. The calibration values will only be over-written when the calibration process completes. Figure 20 - Panel EV calibration starting...
  • Page 18 7. The Camera Tester will automatically boot and begin running. 8. Unplug the micro USB cable from the Camera Tester 9. Connect the 12V DC power 10. On startup, observe the software version under the Reveni Labs logo to see it has updated successfully.
  • Page 19 Service and Repairs Please contact Reveni Labs directly if your Camera Tester has a problem and needs repair. Spare and replacement parts are available and the Camera Tester was designed with repairability in mind, so shipping it in for repair shouldn’t be necessary. Please use the Contact Us link below to get in touch.
  • Page 20 Never use the Reveni Labs Camera Tester in an environment containing flammable gasses as there is a danger of explosion or fire. Do not allow children to play with the Reveni Labs Camera TEster as it and its parts are small enough to present a choking hazard.
