So you just got a cool new high-speed camera. Now what? This Quick Start guide gives you a crash course to get you up
and running with your new camera.
IMPORTANT - The camera ships with a CS-C adapter ring installed, as well as a dust cap. Be sure not to accidentally
remove the CS-C adapter when removing the cap. The CS-C ring is shown below.
Figure 1 - CS-C adapter

Set up
Insert the battery into the camera's battery compartment. To open the door, push the latch towards the back of
the camera (LCD side) with your fingernail, and pull up.
Close the battery door, ensuring the latch is pushed back while closing. Release the latch when the door is nearly
flat against the case, and firmly push the door closed until the latch clicks in fully
Remove the body cap and install the lens by screwing it onto the mount. For the Computar 12.5-75mm zoom
lens, the CS-C adapter needs to be left on. If you're using another lens, check which type it is to determine
whether or not the CS-C adapter is needed
Store the lens and body caps in a safe place. Make sure not to forget where you left them
Powering up, charging, and powering down
It's recommended to fully charge a new battery before running the camera on battery power. Let the battery charge at
least until 80% (LED flashes green/orange). This should take less than 2 hours.
Plug the AC adapter into mains power and into the camera. The LED on the top of the camera should illuminate
to indicate external power is present.
The camera behaves just like your laptop, it charges whenever plugged in, and you can use it while charging. The
battery does not need to be installed to run the camera on external power.
Press and release the power button to power up the camera. It will take approximately 30 seconds to boot up
and show the menu and image
To power down the camera, press the power button for one second, then release. A minimum press of 0.5
seconds is required to avoid accidental shut down. Don't continue to hold the button; holding it for four seconds
or more forces a hard power down. Just like your computer, the camera needs to shut down properly to avoid
potential problems with the operating system. Don't force a hard power down unless the camera is
unresponsive and will not power down normally.
Taking Shots
1. Power up the camera
2. Set resolution in Record Settings - Camera powers up at 1280x1024
Tip - Don't be afraid to turn the resolution down to get a higher frame rate. Frame rate is resolution too -
temporal resolution. Horizontal resolution below 336 pixels doesn't increase speed.
3. (Optional) - For best quality, do a Black Calibration (Black Cal). Close the iris or cap the lens, then tap Black Cal.
Only required once after changing resolutions.
4. (Optional, for color cameras) - Set white balance. Place a white card at the center of the frame and tap White
Balance.
5. Frame and focus. For best sharpness, use an iris of F/2 or above.
6. Press record or click the red record button to start recording
7. Stop the camera after the event occurs, using either the red button on the camera, the Stop button on the
menu, or the optional remote trigger switch.
Playback
1. Tap Play to go to playback mode
2. Use the slider, jog wheel or forward/backwards play buttons to review the video. Click in and hold the jog wheel
clicked while turning to go fast (40x faster than non-clicked).

Saving
1. Ensure an SD card is in the camera. You MUST use a Class 10 or faster SD card from a reputable manufacturer,
otherwise frames may be dropped during save. The card must be formatted FAT32.
2. (Optional, highly recommended) - Use Mark In and Mark Out to select a region to save. Position playback where
you'd like saving to start and tap Mark In. Repeat using Mark Out for the location you'd like saving to end. Saving
the entire buffer can take a long time, especially at low resolutions.
3. Press Save and wait for save to complete
4. If the video is extremely valuable (unable or expensive to recreate the shot), remove the SD card and use a PC to
check that the video saved properly without dropped frames. This is especially important when using a new
brand of SD card for the first time.

To shut down the camera, press the button for 1 second then release. Presses less than 0.5s will be ignored to
reduce the chance of accidentally turning off the camera.
Holding for 4 seconds forces a hard power down. Do this only if the camera software has crashed and won't
respond. Like a PC, the camera needs to shut down properly or file system damage may occur, requiring a
reflash of the OS SD card.

Lens Selection
Lenses vary in their image circle, that is, how large an image sensor they can cover. Chronos 1.4 uses a 2/3" image
sensor (actual sensor dimensions are 8.45 x 6.76mm) . Lenses designed for smaller sensors can be used, however the

Chronos 1.4 User Manual - Software version 0.1 Rev 1 - June 2017

image will not cover the entire sensor. This is called vignetting and is visible as a black ring around the outside of the
image frame.

Trigger IO
Two trigger IO and one isolated trigger input are available on the camera.
Trigger IO 1/2
These non-isolated IOs are referenced to the camera's power and chassis ground, and can provide either input
functionality with selectable threshold (0-6.6V) or 5V TTL level output. These IOs are protected against damage when
connected to voltages of 30V DC/AC RMS and +/- 50V peak.
The 20mA output drive is suitable to directly drive terminated coaxial cable, and will produce 1V into 50Ω, with rise and
fall times time of (typically) 10ns or faster. Unterminated operation will result in a much slower fall time.
[Schematic of Trigger IO 1/2]
Trigger In 3
This input is isolated input via an optocoupler. A logic low input is a voltage from -30 to 1V, and a high level input is a
voltage of 3 to 30V. Voltages between these ranges (1 to 3V) are undefined. This input has built-in 1.2kΩ resistors to
correctly drive the optocoupler, and is protected from differential voltages up to 30V DC/RMS AC and +/- 50V peak.
Trigger In 3 is rated for SELV (safety extra low voltage) circuits only, up to a maximum common mode voltage of 60V
above ground.
DANGER: The isolated input is not rated for safety isolation. Never use any of these inputs to connect directly to mains-
referenced circuits. If triggering from AC mains is needed, external isolation is required.
[Schematic of Trigger In 3]
Storage devices
All storage devices must be formatted FAT32. No other filesystems have been tested, but EXT2, EXT3 and EXT4 may
work. NTFS and exFAT support are planned for release in future software updates.
SD cards are recommended as storage devices rather than USB drives. Use only Class 10 or faster SD cards to ensure
successful saving without dropped frames. Saving to USB is functional, however many USB flash drives are not fast
enough to save video without dropping frames. USB external hard drives typically work well.
When using a new storage device, always test it by making and saving a recording then playing it back on a PC.
Problems typically show up as jumpiness or dropped frames.

Setting resolution and frame rate
Chronos 1.4 allows you to trade image resolution for frame rate. In many applications, temporal resolution (frame rate)
is far more important than spatial resolution (image resolution). Don't be afraid to turn the resolution down!
Frame rates can be set on the record settings page. This page is shown below:
[Picture of record settings page]
The image resolution can be adjusted in two ways. Common preset resolutions are available from the drop down menu
on the bottom left. There are also direct controls of resolution at the top right. Resolution can be adjusted in increments
of 16 pixels horizontally and 2 pixels vertically. Tap on the text box to enter a resolution using the keyboard, or use the
up/down buttons to adjust in minimum increments. As the resolution is changed, the Region of Interest (ROI) display
shows the resulting image size within the full 1280x1024 image sensor resolution. The maximum frame rate and
minimum frame period is displayed under the ROI display.
Once the desired resolution is set, the frame rate can be adjusted anywhere from 0.025fps up to the maximum
displayed under the ROI display. The Max buttons will set the resolution and exposure to their respective maximum
values for the current resolution.
Custom resolution calibration
When using resolutions other than those shown in the Common Resolutions dropdown box, it is very important to do a
black calibration, as only the Common Resolutions are black calibrated at the factory. When a new (never before used

Chronos 1.4 User Manual - Software version 0.1 Rev 1 - June 2017
Page 15 of 18
on this camera) resolution is selected, a basic black calibration is done with the shutter at minimum. This allows a
reasonable image display for immediate use, but a full black calibration is required for best quality.
Black Calibration
For best image quality, the camera automatically subtracts a black reference image from all normal images during
operation. This corrects for pixel offsets that occur on the camera's image sensor. This black reference is updated by
doing a black calibration.
Black calibration is separate for each resolution and gain setting, ie. a black calibration done at 1280x1024 0dB gain does
not apply to 1280x1024 6dB gain.
For best image quality, perform a black calibration:
After changing the resolution, frame rate or shutter speed
After the camera's temperature has changed significantly
After the camera has reached a stable temperature
It is recommended to let the camera reach normal operating temperature before performing a black cal. Let the camera
run for about 15 minutes to reach normal operating temperature.
Performing Black Cal
Perform the black cal by either closing the iris fully, or (if the lens doesn't have an iris that can be fully closed) putting the
lens cap on. Once all light is completely blocked from entering the image sensor, tap the black cal button on the main
screen. The record LED will flash for a short period as the camera records the black reference frames. The black
reference will then be calculated by averaging 16 frames. This process takes some time, up to about 25 seconds
depending on resolution. This will be sped up greatly in a future software update.
Once the record light has flashed and is out, you can safely open the iris or remove the lens cap, as the black reference
frames are fully captured. You can continue setting up your shot (such as focus) while the black cal is being computed.
Once the black cal is done, the message will go away and the camera is ready to use. The black cal is persistent across
restarts and will be remembered the next time you use the same resolution.

Maintenance and care
Optics
Keep the optical area clean when changing lenses by keeping the body and lens mount caps on when the lens is
separated from the camera
If the lens or sensor/IR filter is dusty, remove the dust with air using clean, dry compressed air, dusting gas, or a
dusting squeeze bulb.
If the above is not able to remove the dust, use a brush or lens pen.
If there is dust under the IR filter, you can remove the filter for cleaning. See Removing the IR filter.
Camera body
Do not expose the camera to moisture, rain, or excessively dusty environments, contamination may enter the
camera and cause damage.
The camera body can be cleaned with a lint-free cloth, and optionally a small amount of rubbing alcohol. Do not
use excessive liquids as they may enter the camera body.
Screen
The touchscreen surface is glass. Don't strike it with hard objects or put excessive pressure on the screen, or the glass
may break.
The screen should be cleaned with a soft lint-free or microfiber cloth.
A small amount of glass cleaner or rubbing alcohol may be applied to the cloth if required. Don't use excessive
amounts, and don't spray glass cleaner directly on the camera.
Storage/Shipping
Store the camera in a cool, dry, and clean location.
When shipping the camera, it's recommended to put it in a plastic bag with desiccant to avoid problems with
condensation during temperature changes.
If the camera will be stored for more than a few weeks, charge or discharge the battery to approximately 40%
charge, then turn off the camera and remove the battery. This will minimize battery capacity degradation during
storage
Always remove the battery for shipping to avoid the possibility of the camera turning on in-transit.
