Autocapture Feature
The Autocapture Feature makes it possible to make a manual cali-
bration that is semi-automatic when the input signal in measured.
To be able to utilize the Autocapture Feature the instrument data
has to be set as follows:
• Input Method field set to “Measured”,
• Calibration Method field set to “Automatic” and
• Maximum Allowed Calibration Point Deviation field set to
greater than zero.
Then MC5P tracks the input signal and once the input signal is
inside the Maximum Allowed Calibration Point Deviation limit
for a time period defined in the Setpoint Delay, the input and out-
put values are automatically saved.
Activate the Autocapture Feature from the menu available when
viewing the calibration windows. When activated and a calibration
point is about to be captured (MC5P is waiting for the Setpoint
Delay time to pass while the measurements are stable enough and
within the Maximum Allowed Calibration Point Deviation limit),
an hourglass is shown in the input measurement window’s lower
right corner.
When autocapture “snatches” the input and output signal values,
MC5P emits a beep and the next target value for the input is dis-
played.
Examples of Instrument Calibration
This User Guide has only a few examples of how to calibrate an
instrument. Many calibration procedures not presented here are
either very similar to the ones presented in the following chapters
or they can be “combined”, e.g. the calibration of a Pressure Indi-
cator/Recorder is partly done as a Pressure Transmitter and partly
as a Temperature Indicator/Recorder calibration.
Use the information presented in Part B of this manual when con-
necting/calibrating instruments that do not have a separate calibra-
tion procedure presented in this part.
The following calibration examples are presented in this manual:
Pressure Transmitters on page 114,
Temperature Sensors on page 116,
Temperature Indicators and Recorders on page 118 and
Electrical Limit Switches on page 120.
