Page 16: Automatic Operating Mode
PRESYS Instruments TE -25N / TE-35N / TE-50N The countdown of the stabilization time is only started when the block temperature reaches the programmed temperature and stabilizes withing a range of aproximately 0.05 ºC. At this time the buzzer beeps, in case it is configured to YES. - Page 17 TAGMAN with the key ENTER. The option ADDRESS selects the communication address of the TE-25N/TE- 35N/TE-50N calibrator. The communication protocol used is ModBus - RTU, with no parity and baud rate of 9600. The calibrator communication with the computer can use RS-232 or RS- 485, for network option, according to the communication interface used.
