The data format for Analysis data output consists of nine ASCII characters. Seven
characters show the value in engineering format (See “Engineering format” on
page 17), one character shows the result of the test, and one character shows line
feed (LF).
Table 8-8. The character indicating the result of the test is one of the following.
Example: 2.5E-04R (LF)
This example is a line feed (LF), R means that the test was above the Reject Level
limit, and the value was 2.5E-04.
For passive probes (for example P50 and AP57*) data is printed when a signal is
detected above
Reject Level or when the print button is pressed. Activate this under
Measure Button menu.
For active probe AP29, data is printed at end of measurement sequence.
Printing of the current value can also be requested by an RS232 command or
ordered manually by pressing
PRINT . See “Connector pin configuration” on page 33.
* A custom APC program setting the MEAS flag prints as AP55/AP29 ECO and an APC
program not using MEAS flag prints as P50.
Detection data output
The Detection Data Output option is intended for automated scanning of weld seams
etc.
Note: The Detection Data is expressed in arbitrary units. Detection Mode signal is not
affected by calibration!

Character Result of the test
A Accept. Previous test was below Reject Level limit.
R Reject. Previous test was above Reject Level limit.
P Rejected by Purging. Previous test was above purge limit
(and Reject level limit).
C Calibration approved. Previous cycle was calibration.
Calibration was approved.
F Calibration failed. Previous cycle was calibration.
E Test interrupted by “Error” that occurred during cycle
(probe or sensor error etc.).
