79. uracy claims The term accuracy is defined by ISA S37 1 as either the ratio of the error to the full scale output FS or the ratio of the error to the reading RDG Note that the definition of accuracy is not the summation of some or even all of the possible error source maximum limits The true accuracy of an instrument is relative to the actual error introduced by the calibration transfer standard plus the actual error not eliminated from the instrument s indicated output Therefore an instrument s accuracy can be manipulated by introducing more or less actual error through the choice of a calibration standard or its accuracy can be varied by the elimination of actual errors inherent in the instrument For example if an instrument has a known error due to being used in an attitude or tilt the FS zero shift error can be eliminated by re zeroing the instrument in the tilted position Even RDG sensitivity shifts can be eliminated mathematically or by controlling the attitude of the instrument during its calibration A 1 RUSKA 7615 Users Manual A 2 The key to eliminating an error is knowing its source and type along with its polarity and magnitude Generally the source 1s simple to detect and 1s represented by the specific parameter The type is usually a function of the instrument s design and manufacturing process Within a given instrument an error can be either random or systematic as well as random or systematic within th
80. y a relief valve Reservoir Select Valve This three way valve is located on the back panel of the instrument Internal or external reservoir is selected using this valve If external reservoir is selected then an external reservoir must be connected to the external reservoir port connection Normally this valve is set in the mid position off during shipment RUSKA 7615 Users Manual 2 6 Chapter 3 Installation Introduction This portion of the manual discusses initial installation for the RUSKA 7615 Calibrator Installing the Calibrator is a relatively simple process of unpacking the Calibrator powering it up and then using the front panel to configure the system Unpacking the Calibrator Carefully unpack all components checking for obvious signs of damage In addition to any nonstandard items ordered with the Calibrator the shipment should contain at least the following items e RUSKA 7615 Calibrator e power cord and this user s manual If necessary report any shipping damage to the freight agency Remove masking tape strings and packing materials from all components If possible save the packing materials for future use Finally install the Calibrator in a location that meets the requirements listed in Table 3 1 Note The Calibrator should not be subjected to mechanical shocks during installation or use It should be mounted on a rigid bench or in a sturdy 19 inch rack 3 1 RUSKA 7615 Users Manual Tab
