STANDARD RANGES TABLE

B)  RTD (Resistance Temperature Detector)
Input: for RTD Pt 100 

W, 3-wire connection.

Input circuit: current injection.
°C/°F selection: via front pushbuttons or serial link.
Line resistance: automatic compensation up to
 20 

W/wire with no  measurable error.

Calibration: according to DIN 43760
Burnout: up scale. NOTE: a special test is
provided to signal OVERRANGE when input
resistance is less than 15 

W.

STANDARD RANGES TABLE

C) LINEAR INPUTS
Read-out: keyboard programmable between
-1999 and +4000.
Decimal point: programmable in any position.
Burn out: the instrument shows the burn out condi-
tion as an underrange condition for 4-20 mA, 1-5 V
and 2-10 V input types.
It shows the burn out condition as an underrange or
an overrange  condition (selectable by soldering
jumper) for 0-60 mV and 12-60 mV input types. No
indication are available for 0-20 mA, 0-5 V and 0-10
V input types.

D) LOGIC INPUT
The instrument is equipped with one input from
contact (voltage free) for setpoint selection.
Contact open = Main setpoint.
Contact closed = Auxiliary setpoint.
NOTES
1) Use an external contact with a contact rating

better than 0.5 mA, 5 V DC.

2) The instrument needs 100 ms to recognize a

contact status variation.

3) The logic inputs are NOT isolated by the

measuring input.
