8、ter may be equipped with Option 005 Data Storage. Up to 50 complete DVM readings may be entered into Data Storage at up to 1000 readings per second. The output of these stored readings may be governed by an external device. Data Storage is ideal for use with a digital recorder where readings may be

9、taken at high speed, stored, then outputted at 10 to 20 lines per second. 1-3. Each stored reading includes all information generated by the 3480A/B including input voltage magnitude, range, function, polarity, and overload. The number of readings stored is selectable up to 50. When stored readings

10、are outputted, two additional digits are added to identify the reading number. All output lines are isolated from the 3480A/B input terminals. 1-4. Option 005 Data Storage includes Isolated BCD. When Data Storage is disabled, the output of the 3480A/B becomes identical to that of Isolated BCD. 1-5.

11、The 3480A/B offers a wide variety of plug-in units which may be used with Data Storage. These plug-ins include the 3481 A with a single 10 V de range, the 3482A with 5 de ranges, the 3484A with 5 de ranges, 5 true rms ac ranges and 6 S1 ranges and the 3485A with up to 50 input channels plus 3 de ran

12、ges. 1-6. Any of the above capabilities including Data Storage may be purchased in a self-contained data logger, the 2070A, which includes the 3480A Multifunction DVM, the 5055A Digital Recorder plus any 3480 plug-in. A special rear panel includes the major Data Storage control lines in the form of

13、easy to use switches. 1-7. Accessories Furnished (with Data Storage only). 6 foot Y cable with Remote Control lines and BCD lines split and left unterminated.

18、 Recorder . . . Storage Enable: application of Low state enables Data Storage, otherwise the output is identical to Isolated BCD. Scanner Control Enable: application of Low state allows 3485A Scanning Unit to be used with Data Storage. Storage Limit (4 lines): limits number of stored readings to 10,

19、 20, 30, 40, or 50. If all lines are open, 50 readings are stored. Storage Flag: used to trigger digital recorder. Remains High during storage cycle then drops Low to indicate data is ready to be printed. Goes High during printing cycle then drops Low to indicate next reading is ready. Printer Hold-

20、off: application of High state (by digital recorder) disables internal sampling and gates a reading out of storage. When Used With A Computer . Storage Enable: application of Low state enables Data Storage, otherwise the output is identical to Isolated BCD. Computer Control Enable: application of Lo

21、w state allows Data Storage to be used with a computer. Measure (Encode): application of Low state initiates a reading which is in turn, entered into storage. During an output cycle, Measure gates individual readings out of storage. Storage Flag: line goes High to acknowledge each Measure. Line drop

22、s Low when Data Storage is ready to accept the next Measure. Status Flag: line indicates if Data Storage is storing data by remaining High or outputting data by remaining Low. Internal Measure Inhibit (Interface Hold): application of Low state disables internal sampling but allows DVM to be external

23、ly triggered by Measure. Jump: overrides the normal requirement of filling all storage locations selected by Storage Limit before outputting data. Allows a non-multiple of 10 readings to be stored then outputted. 1-2 Lines Available For Special Applications . Input Cycle Hold Causes continuous input

Allows readings which have been stored to be gated out. Measurement Hold: prohibits all internal and external

25、 sampling but allows the completion of one complete storage and output cycle. Preset Trigger Allows preset number of previous and next readings to be stored, then outputted. This line is normally used with Input Cycle Hold grounded. O line: stores previous 0 readings and the next 50 read- ings.* 1 O
