12. Use the software to configure the MTL831C(s) to match the old MTL830B system settings you recorded,
a. NOTE: The Honeywell system sends most of the channel configuration to the MTL830C system. However, the
number of wires used for RTDs is not included in the configuration data sent by the Honeywell system. The default
channel configuration for RTDs is 3-wire. If mV, thermocouple, and 3-wire RTD are the only channel configurations
used then no MTL831C configuration is required. If any channels are connected to 2- or 4-wire RTDs, set those
channels using the software as described below.
b. On each MTL831C tab where MTL831C is configured to measure RTDs, select the correct number of wires for
the RTD for each channel. NOTE: this is only required for channels connected to 2- or 4-wire RTDs. Any channels
connected to RTDs and left as “Not Configured” will be treated as 3-wire RTD when the Honeywell system enables
them.
c. Click the Download -> MTL831C button.
d, NOTE: The MTL838C remembers the last way a channel was configured for RTD even if it is later unconfigured.
If the Honeywell system then configures the channel for RTD, it will use the number of wires that was last
configured by the software. If you see unexpected behavior with RTDs use the software to configure the number of
wires on ALL RTD channels so that you know they are correctly configured.
13. Disconnect the computer from the MTL838C. NOTE: The Honeywell system will not be able to communicate with the
MTL830C system while the computer is connected to the MTL838C.
14. Confirm the new system is operating properly using the Honeywell system.
