calibration reference

[′kal·ə‚brā·shən ‚ref·rəns]
(analytical chemistry)
Any of the standards of various types that indicate whether an analytical instrument or procedure is working within prescribed limits; examples are test solutions used with pH meters, and solutions with known concentrations (standard solutions) used with spectrophotometers.

"I requested samples of the material, calibrated an instrument at SolveTech using their material, and then created calibration frames, which are used as a calibration reference. This calibration of the instrument used the NIST-traceable calibration.
When UAV images are mosaicked into a larger image of a field or route pack, each individual image is relatively small, so it is impossible to include a calibration reference in every image.
"One of the ways that we are helping customers adapt is with the Multi-Channel Antenna Calibration Reference Solution," Leeke said.
The 3D calibration object usually consists of two or three orthogonal planes with each other, and 2D calibration reference object is usually a plane with some patterns on it, as shown in Figure 1; the patterns are circle and chessboard.
Theoretical and experimental work has been conducted to develop a calibration reference device that could be used in test facilities that conform to ANSI/ASHRAE Standard 52.2 2007.
Accurate to [+ or -]0.05% FS, the pressure gauge can be used as a calibration reference or in applications where high-accuracy pressure measurement is required, such as safety valve checks and system pressure verification.
Accurate to A 0.05 per cent FS, the IPI can be used as a calibration reference or in applications where high accuracy pressure measurement is required from safety valve checks to system pressure verification.
