J1 – Shunt Resistor Connections. Two terminal pins are provided via the J1 rear connector

for installation of an external shunt resistor. Terminal connections are used to install a user

defined resistor as determined by the sensor's calibration data sheet or pre-determined by

the user. When an externally installed resistor is used, the ANALOG CONTROL switch 5 is

required to be in the External position (Switch 5 DOWN).

The 3770 unit comes with an internally installed 59K Ohm resistor, as standard, and

Note:

enabled when the front panel ANALOG CONTROL Switch# 5 is in the Internal position

(Switch 5 UP).

When a sensor has an integrated shunt resistor, the ANALOG CONTROL switch

Note:

setting needs to be in the External position and a shorting wire in place of the external

shunt resistor position. This provides the electrical path for the Calibration Sense line to

enable the sensor's internal shunt resistor when the + or – Shunt Calibration rear terminals

or push buttons are activated.

NOTE:

Daytronic Shunt Calibration circuit, when activated, will place the Shunt resistor across

the + Sense Line (for positive shunt) or the – Sense Line (for negative shunt) with the

connection of the Sensor's Calibration Sense line located on the J2 connector - which is

recommend to be connected to the + Signal line. When not activated, the Calibration Sense line

is buffered as to not affect the sensor's operational characteristics.
