Clarity - INT9 A/D converter Brief Description 1 Brief Description This manual describes the use of the INT9 converter with Clarity software ver. 2.5 and later. INT9 is an internal 24-bit A/D converter card that measures the voltages of chromatographic and electrochemical detectors. 1.1 INT9 Acquisition card • Up to 4 dataacquisition channels on one card (one and two channel versions are also available). • The channels are completely independent sigma delta integrating A/D converte

Clarity - INT9 A/D converter Brief Description A/D Converter types in general Prior to collecting and processing the chroma- tographic signal by a computer, the analog signal of the detector must first be converted to digital form using an analog/digital (A/D) converter. In principle, there are three types of A/D converters – sampling, integrating and ΔΣ (Delta-Sigma - with continuous integration). The INT9 card uses Delta-Sigma integration. Advantages of the INT9 A/D converter • No

Clarity - INT9 A/D converter Using the INT9 card Supply Frequency Allows to change the Mains Supply Frequency Suppression. It is used for suppresing the interference on the specified frequency level. This setting influences the sampling frequency as well. Note: In most parts of Americas, the 60 Hz Mains frequency is usual, while the rest of the world tends to use 50 Hz Mains frequency (pre-set as default). The 50 Hz frequency is common in countries using 230V power supply, while the

If there is only one detector (channel) configured on the Clarity Instrument, this control will not be displayed. Range Selects the input voltage range (in mV). The selected range corresponds to the maximum output voltage of the detector that the A/D converter can still process. Available ranges for INT9 card are 156, 1250 and 12 123 mV.
