In chemistry, absorbance or decadic absorbance is the common logarithm of the ratio of incident to transmitted radiant power through a material, and spectral absorbance or spectral decadic absorbance is the common logarithm of the ratio of incident to transmitted spectral radiant power through a material.he optical depth equals the absorbance times ln(10). The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).
1 At a lower gain, the noise decreases, but the shutter speed becomes slower to compensate for the lack of brightness, causing camera shake or subject blur.  When recording using [Smth Slw REC], the upper limit of [AGC Limit] is [15dB].
Ambient Air Temperature Sensor. The ambient (ATC) or outside air temperature sensor is an (NTC) negative temperature coefficient sensor that informs the semiautomatic/automatic temperature control system of outside air temperature.The NTC sensorâs resistance decreases as the outside air temperature increases.The computer uses this input, along with other in-car temperature sensors to control temperature and blower speed. When thereâs a problem with this sensor, performance will suffer and the compressorâs clutch may not engage.utomotive air conditioning systems use NTC sensors to monitor air temperature. The In Car Temperature sensor (ICTS) is an NTC that monitors the air temperature of the passenger compartment. The ambient temperature sensor (ATS) monitors the air temperature outside of the vehicle.
