The other two wires will cancel because each is in an opposite leg of the bridge (provided they are the same length). 4 Wire : Use of a digital voltmeter with a current source replaces the other 3 bridge bridge completion resistors with one referance resistor and makes the RTD insensitive to the length of the lead wires. *inldhelp Input Lead Resistance : See owners manual for complete details. *ratehp Slow : In the slow position the read rate is approximately 3 readings/sec.

Important note : Decimal point chosen for these values should be equivalent to the decimal point position you have already selected. *spenbhp Setpoints Enabled : "Yes" activates the setpoints to respond to the parmeters you have programed in. *sbrwhelp Single read/write data or Block read/write data : This allows you to first read the data currently programmed into the MICROPROCESSOR or EEPROM, change it, and then write the changes back to them. This can be done in two different ways. " Single read/write data " will operate on each individual menu item, whereas, " Block read/ write data " does the entire menu page. Note : In the " Block read/write data " mode changes will only be implemented as a block when you leave than menu. *spwrhelp Source of Power : *prthel Communication's serial port : Specify communication serial port number ( 1 or 2 ) you want to communicate with DP41 meter. Press "F2" for choices. *nothelp Please refer to the Owners manual for more information or contact OMEGA ENGINEERING. *analhelp Analog output signal : If you selected 4 - 20mA dc for Analog output signal then you have to use OUTPUT SCALE and OFFSET to rescale and offset for 4 to 20mA. *addhelp Meter Address : Can be from 000 to 199.
