PRELIMINARY HARDWARE SETTINGS

1)Remove the instrument from its case.

2)It is necessary to set J106 according to the desired input type as shown in the following figure.

INPUT			J106

TYPE	1-2	3-4	5-6	7-8	9-10
TC-RTD	open	close	open	open	open
60 mV	open	close	open	open	open

5 V	close	open	close	open	open
10 V	open	open	close	open	open
20 mA	open	open	open	close	close

OPEN INPUT CIRCUIT

This instrument is able to identify the open circuit for TC and RTD inputs.

The open input circuit condition for RTD input is shown by an "overrange" indication.

For TC input, it is possible to select overrange indication (standard) or underrange indication set- ting the CH101 and SH101 according to the follow- ing table:

Overrange (STD) CH101		= close SH101	= open
Underrange	CH101	= open SH101	= close

Both pads are located on the soldering side of the CPU card

NOTE : the not used jumper can be positioned on pin 7-9
