  • Page 5: About This Manual

    (GAGE models only). Introduction Using microprocessor technology, the rack-mountable DLR3110 instrument offers a combination of features, performance, versatility and reliability not previously available in a single, rack-mount pressure calibration instrument. Some of the features of the DLR3110 are listed below: •...

    Keep original shipping carton for repacking in case repair is necessary. Repacking If the DLR3110 must be returned for repair, recalibration, or modification, be sure that it is properly cushioned and packed and that a description of the work to be performed is included. The original shipping carton should be kept for this purpose.

When AUTO TARE is enabled, pressing the key automatically tares out TARE the value of the current pressure display reading and shifts the display to the P (delta P) mode. The resultant ZERO reference reading is useful in cases where it is desirable to subtract the atmospheric pressure from an absolute reading to obtain a quick gauge reference.

    Serial Input/Output The DLR3110 offers easy access and configuration of two serial communication ports. Both communication ports are ASCII-compatible and thus the serial data output formats are compatible with most printers, scoreboards, or other remote serial devices. Port One may be configured for bi-directional full duplex or half duplex (duplex = two way communication) mode of operation while Port Two is restricted to a simplex output mode only (simplex = one way communication).
