4.5.2 Parameters of a Sensor
After entering the password (9373) in menu 2SYSTEM-2.5PASS, the sensor can be installed in the calibration
menu. Following parameters are possible:
Sensor__ Sensor no. 3 , Sensor 0 – 9 possible
POINTDIS 200,0 Match meas. range and decimal point (max. 9999)
UNIT _kN, 1 – 3 digit unit possible
DESIGN Press, up to 8 digit name (or numbers) arbitrary
CALIB PAS_wCON , Select Passive with cal. control. See data sheet of sensor
0% LOAD Unload sensor, 0% value of sensor is assigned to display
100% CON Autom. Calibration, 100% value of sensor is assigned to display for example 200,0 kN
SAVE ENTER or ESC , Confirm or discard
4.5.3 Measuring with the E3907
In order to be able to now measure with this sensor, the sensor " Press" is selected in the measuring mode. During
a measurement, a minimum and maximum value buffer can be called with the
MINUS key. The respective
displayed minimum or maximum value can be deleted by ENTER.
If the measured value shall be sent through an interface to a pc or printer, the baud rate must be adjusted to the
receiver and at SCI-MODE the operating mode must be chosen. For example: HAND, a measured value with time
is displayed during every keystroke on ENTER while measuring.
For data logging, adjust operating mode in the logger mode, e.g. choose AUTO and interval time e.g. 10 sec and
change to measuring mode. A measured value with time is now stored every 10 sec. In mode LOGGSEND, these
data can then be sent through the interface.
Notation:
When running the device via USB port, the baud rate must be set correctly. This must match the
baud rate of the virtual com port on the receiving PC.
4.6 Serial interface
The E3907 handheld instrument uses for the serial data transfer either a RS232 or a USB interface.
The USB interface is managed on the PC as a virtual COM port. For the use of the USB port, the
PC must have a Windows operating system (2k, XP, Vista, 7) and it must be installed the USB
drivers from tecsis. After installing the drivers, the virtual COM port below can be used as described
below.
4.6.1 Transfer rate / specification RS232 (V.24) / USB
Parity:
none
Number of data: 8 (1Byte) 8N1
Stoppbit: 1
Baudrate adjustable (2400; 4800; 9600; 19200; 38400; 115200 Baud)
Even in USB mode, the baud rate in the E3907 handheld device and the connected device must
match.
4.6.2 Operation via the serial interface
Through the serial interface, measurement values can be issued singly or automatically by the E 3907.
The commands can be sent to the E 3907 via a terminal program or PLC.
If the E3907 is in the measuring mode, following commands are available:
