| The XL120D can be equipped with 8 input channels and the XL122-D and XL124-D with 16 input channels. Both have 16 MB internal memory as well as capacity for external storage mediums such as CF or SD card; and USB memory. The analog input section accepts DCV, Thermocouple and RTD with measurement intervals from 100ms(8 channel only), and 200ms up to 1 hour (both models). The digital input section can support 1 channel for pulse input and 2 channels for logic inputs. In addition, alarm summaries, log displays and review functions can be retained and displayed in this powerful, but compact portable data logger (weighs 28 ounces w/o battery). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

All Channels adopt Universal Insulated Inputs The channels in the analog input part adopt insulated inputs, which means that temperature (thermocouple/resistance temperature detector) and voltage can be set differently for each channel. The digital inputs are equipped with one pulse channel and two logic channels. Best-In class Noise reduction Datum-Y achieves excellent noise resistance rated among the best in the class of handy measuring products. With Datum-Y, stable measurement is possible in various noise environments, such as when measuring inverter-driven machines or thyrister-controlled units that are commonly used for energy-saving purposes Data Saving at 100ms Datum-Y saves data at the maximum speed of 100 ms (when the 8-channel terminal block is used). You can save data in either binary format or ASCII format (for display in Excel). Binary data can be checked on site in the review mode or shown in waveforms using the supplied “D-TOOL” software. Acquisition of Large amounts of data using External Storage Media Acquisition of Large Amounts of Data Using External Storage Media Datum-Y lets you save data not only in its internal memory (16 MB), but also in external storage media such as compact flash memory cards* and SD cards* (up to 512 MB). Data saved in these media can be copied to a USB memory* for easy transfer to a PC. * Use compact flash memory cards, SD cards and/or USB memory whose compatibility with Datum-Y has been verified. |

Spot checking of Acquired data You can check measured data (binary) on Datum-Y right away. Overall trend and alarm output can be checked on the spot immediately after acquisition. While Datum-Y is logging data, you can display past data and current data in the logging review mode for comparison and identification of trend. (This function is available only when binary data is acquired.) Calculation Function Datum-Y is capable of inter-channel calculations (among channels, between channels and constants, etc.), statistical operations (minimum, maximum, average, root-mean-square and peak values from start to end of logging), and scaling. Trigger Function Datum-Y acquires data before and after a trigger (pre-trigger/trigger delay) to help you detect and analyze the cause of an error. You can select the single mode (a trigger is issued only once) or continuous mode (a trigger is issued every time the condition is satisfied). Alarm System Datum-Y can be fitted with up to four alarm output channels. One alarm can be set for each input channel, and multiple channels can be combined freely with AND/OR gates. You can also use the e-mail delivery function to notify specified e-mail addresses upon occurrence or reset of an alarm. Auto Set & Run Function (automatic Measurement Function) Simply connect an external storage medium (CF card, SD card or USB memory) containing a predefined file (AUTORUN.SET), and Datum-Y will change the necessary settings and take measurements automatically. (You need to enable the automatic measurement function of Datum-Y beforehand.) |
