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, AP55 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 39.
* A custom APC program which sets the MEAS flag, will print as AP55/AP29 ECO and
an APC program not using the MEAS flag prints as P50.
Locating data output
The Locating Data Output option is intended for automated scanning of weld seams
etc.
Note: The Locating Data is expressed in arbitrary units. Locating Mode signal is not
affected by calibration!
Table 8-9. Communication specifications.
The data format for Locating data output contains of nine ASCII characters. Eight
characters show the value in engineering format (See “Engineering format” on
page 23), and one character shows linefeed (LF).
The print time is 50Hz continuous streaming data.
RS232 serial communication
The most commonly used Sensistor ISH2000 functions can be started/configured
over the RS232 interface.
Table 8-10. RS232 communication specifications.
F Calibration failed. Previous cycle was calibration.
E Test interrupted by “Error” that occurred during cycle
(probe or sensor error etc.).
