Terminology
A
Adjustment
When you make a calibration and compare two devices, you may find out there is some difference between the two. So, it is pretty logical that you may want to adjust the device under test to measure correctly. This process is often called adjustment or trimming.
Formally, calibration does not include adjustment, but is a separate process. In everyday language the word calibration sometimes also includes possible adjustment. But as mentioned, the adjustment is a separate process according to most formal sources.
As found calibration
The calibration repeat performed to verify the state of the instrument before any adjustments.
As left calibration
The calibration repeat performed to verify the state of the instrument after adjustments.
Asymmetric error limits
The Error Limit Settings window also includes the possibility to define an asymmetry for the error limits, e.g. the positive error limit is double the negative error limit. The Error Limit's Asymmetric Expansion is defined in two fields: The first field defines the multiplier. The value needs to be equal to one or larger. The second field defines which error limit is expanded using the multiplier.

Calibration Repeat
A single calibration task performed for a function. This can be an as found or an as left
Calibration Result
A calibration result is formed of one or multiple calibration repeats and calibration certificate is formed of the calibration result, including each repeat.
Credit
Credits are used to upload calibration results to LOGiCAL.
One calibration result = one credit.
D
Device
A Device is the physical instrument that can be installed into a Position.
E
Error limit
How much error is acceptable for the instrument.
F
Free device
A device that is not linked to a position is called a free device.
Function
A single task done with an instrument, e.g. temperature transmitter, pressure indicator etc. Instruments capable of performing several tasks are called multifunction instruments. Function Type is the description of the function (input/output quantities and ranges) and information concerning the calibration of the function (e.g. calibration points and error limits).

Instrument
Instrument in LOGiCAL means a combination of one of the following:
A position with a linked device and function + calibration procedure
A Free device (not linked to any Position) with a function and calibration procedure.

M
Multi-function instrument
A multi-function Position or Device can carry out several operations, e.g. a temperature transmitter and a temperature indicator is an instrument with two functions
Multiple error limits
An instrument's measurement span may be divided into subranges. Each subrange may have their own constant and relative error limits. For each subrange, the limitations of Reject Error's Constant and Relative parts apply, but only for the subrange they are valid in, i.e. the combined Reject Error limit may not cross the zero error limit within the subrange. Additionally, the subrange's change points may be outside the span but the change points have to be in increasing order relative to the span. The amount of subranges are not limited in LOGiCAL/bMobile. However, MC2/MC4 calibrators do not support multiple error limits at all and MC6 family calibrators support up to 10 error limits.

Organization
An organization refers to a company whose users are using LOGiCAL. The LOGiCAL subscription is made for the organization Organizations are maintained in the Beamex myBeamex application.
P
Position
A Position is the location in a process where a device can be installed. Positions often have symbolic names (tags) like TTI 215 in instrumentation drawings. A Position can be calibrated only when a device is installed because a location cannot be calibrated.
Procedure
The procedure includes information on scheduling, calibration points and instructions for the user in the field.
