Apply the common legs from the RTD (generally the same color RTD leads) to terminals 1 and 2.
Apply the other signal lead to terminal 3. Terminals 3 and 4 must be jumpered together for proper
operation and to prevent any build-up of electrostatic charge on these terminals which could affect
the transmitter readings.

Apply one set of the common legs from the RTD (generally the same color RTD leads) to terminals 1
and 2. Apply the other signal lead pair to terminals 3 and 4. No jumpers are necessary for a 4 wire
RTD input.

ISPLAY
If the unit was ordered with the standard factory configuration, the sensor required is a Type J
thermocouple. The packing slip and a tag on the unit will indicate if the unit was set up to any other
customer requested special configuration. If there is a need to change the configuration of the
transmitter, or to re-range it, use either the LI-1 or LI-2 Display and refer to the procedures described
in SECTIONS 4 (for LI-2), 5 (for LI-1).
NOTE: Even when “In a Hurry”, the use of an appropriate power supply is important. A 24V DC
supply having a current handling capacity of at least 0.1A is commonly used. Always use a
DC (direct current) supply, or suitable size battery.
NEVER CONNECT THE TRANSMITTER
DIRECTLY TO 115VAC.
With the power supply off, connect the + side of the power supply to the + terminal of the
