INPUT SELECTION
To change the input type, remove the instrument from its housing. Grasp
the front bezel sides and pull forward to release it from the housing lock.
Locate the dip switch on the right pcb. Determine the input type desired
and change the dip switch setting as shown to the right.

NOTE : Factory default is set for thermocouple inputs.
After changing input selection with the DIP switches, be sure to change
the InP menu item (page 9) in the Secure Menu.

NOTE: InP menu item factory default is set for type "J" thermocouple,
Iron/Constantan
Scaling for thermocouple and RTD inputs is fixed for each range type.
See page 8 for scale ends.
Scaling for current and voltage inputs is field adjustable by using SCAL and SCAH in the Secure menu. Program
SCAL to the low end value of your transmitter. Program SCAH to the high end value of your transmitter. If the
span of your transmitter is less than 100 units (referred to as 'counts' in these instructions), multiply the
transmitter span by 10 and change the decimal point position in menu item dP.
For example, if you have a differential pressure transmitter with a range of -0.25 to +0.25 inches of water. SCAL
would be programmed to -250, SCAH to +250, and dP to 0.000.
