WARNING Indicates that any improper operation or handling may result in moderate or minor injury, and in rare cases, serious injury or death. Also indicates a risk of serious property damage.
CAUTION Indicates that any improper operation or handling may result in minor injury or property damage.
WARNING
Do not disassemble, repair, modify, deform under pressure, or attempt to incinerate this product. Doing so may cause injury or fire.
This product is not explosion-proof and should not be used around flammable or explosive gases or liquids. Doing so may cause ignition resulting in an explosion or fire.
Do not use air dusters or any spray that uses flammable gas around the product or on the inside of the product. Doing so may cause ignition resulting in an explosion or fire. Do not install this product in any of the following locations. Doing so may cause a fire, damage, or a malfunction.
1. Locations where dust, salt, iron powders, or vapor (steam) is present. 2. Locations subjected to corrosive gases or flammable gases. 3. Locations where oil or chemical splashes may occur. 4. Locations where heavy vibrations or impacts may occur. 5. Locations where the ambient temperature exceeds the rated range. 6. Locations subject to rapid temperature changes (or where condensation occurs). 7. Locations with strong electric or magnetic fields. 8. Outdoor locations or locations subject to direct light. Do not use this product in a non-industrial setting. Doing so may cause induction or radiation interference. This product is not intended for use with nuclear power, railways, aviation, vehicles, medical equipment, food-handling equipment, or any application where particular safety measures are required. Absolutely do not use this product for any of these fields. This product cannot be used in applications that directly or indirectly detect human bodies for the purpose of ensuring safety. Do not use this product as a detection device for protecting the human body. What to do in the event of a malfunction such as smoke being emitted from the product If you detect any malfunction including emission of smoke, abnormal smells or sounds, or the body becoming very hot, immediately stop operating the product and turn off the sensor power. Failure to do so may cause a fire. Repairing the product is dangerous and should in no way be performed by the customer. Contact an OPTEX FA sales representative for repairs.
CAUTION
Make sure to turn the power off before wiring the cable or connecting/disconnecting the connector. Connecting or disconnecting while energized may damage the product or cause electric shock.
Avoid using the transient state while the power is on (100 ms). Output could become unstable, causing unexpected operation.
Do not wire with high voltage cables or power lines. Doing so may cause malfunction or damage by induction. Do not bend the cable when below the freezing point. This may cause the cable to break. Do not drop the product or subject the product to strong impacts. Doing so may damage the product. Follow the instructions in this manual or the specified instruction manual when wiring the product
or the dedicated controller for the correct wiring method. Incorrect wiring can damage the product or the controller, or cause a malfunction. When disconnecting the connector, be careful not to touch the terminals inside the connector, and do not allow foreign objects to enter the connector. Install this product as far away as possible from high-voltage equipment, power equipment, equipment that generates large switching surges, inverter motors, welders, or any equipment that can be a source of noise. When connecting or disconnecting the cable, make sure to hold it by the connector portion, and do not apply excessive force to the cable.
Handling Precautions
After carefully considering the intended use, required specifications, and usage conditions, install and use the product within the specified ranges.
All specifications may be changed without notice. When using this product, it is the responsibility of the customer to ensure necessary safety designs
in hardware, software, and systems in order to prevent any threat to life, physical health, and property due to product malfunction or failure. Do not use this product for the development of weapons of mass destruction, for military use, or for any other military application.

Power-save display
If no button operation is detected for 10 minutes, the settings and measurement displays will turn off. During this period, the PWR LED (power indicator) will flash every second. Pressing any button will return the display to normal. Return operation is also possible when the keys are locked.
External input
Functions such as offset execution can be assigned to external inputs. Assigned functions will work simultaneously on the Ch 1 and Ch 2 heads.
High-accuracy analog output
The CDA-DM2 is equipped with two 16-bit resolution analog output circuits. The voltage and current for each analog output can be independently switched as desired, and output values can be specified as measurement values or calculation results for each channel as desired. For details, see the CDA series user’s manual.
Key lock/unlock
Press and hold (B button) for at least 2 seconds on the measurement screen or calculation results display screen to lock the keys. While the keys are locked, “Key Locked” is displayed at the bottom of the measurement screen. Press and hold (B button) again for at least 2 seconds to unlock the keys.
