Measurement accuracy, temperature drifts, max and min indications
All accuracies and min/max indications are referred to an ambient temperature range of 25°C±5°C, relevant humidity ≤60% and scale ratio (electrical/displayed scale) equal to 1. The conversion into °F is obtained acting on the electrical/displayed scale ratio. Array *<45Hz >65Hz= ±(0.5%RDG+3DGT) 0% to 25% FS;±(0.5%RDG+2DGT) 25% to 110% FS.
( )The min. indication for TRMS measurement (AC or DC) is 0; it is possible to modify the decimal point position.
All accuracies and min/max indications refer to an ambient temperature range of 25°C ±5°C, relevant humidity ≤60% and scale ratio (elec-trical scale / displayed scale) equal to 1. The conversion into °F is obtained acting on the electrical scale / displayed scale .

BR SX: RS485 4-wire connection:additional devices provided with RS485 port (indicated as RS1,2,3...N) are connected in parallel. The termination of the serial port is carried out only on the last instrument of the network. The serial module is provided with a jumper for the termination of the RS485 network as shown in the figure above.
Note:particular types of cables or plants may require an external termination. For the network connections use twisted cable type AWG26.

Programming UDM35 by means of PC
Wiring diagrams of optional modules (cont.)
UDM35 is programmable by PC by means of the UdmSoft software (available on request). The user can program all parameters of UDM35 that will be subse-quently uploaded and set in the instrument by the RS485 network (BRSX).
Should UDM35 be without the RS485 serial module, all programming parameters will be uploaded and set in the instrument by the RS232 auxiliary serial connec-tion (1) located on the side of the measuring input module using the special con-nection cable (2) available on request, as shown in the figures on the left. It is also possible to program the instrument using the dot connector (1) by means of the HyperTerminal Windows functions of a PC.
Note:the RS232 auxiliary port IS NOT insulated from the measuring inputs.
Ordering code of the cable (2): UCOM1
BO SY: RS232 direct
connection to PC by means of COM port.RS232 has no termi-nalization.
