NOTE:

1)Do not run RTD wires with power cables.

2)Ground shielded cable at one end only.

3)Use the correct size copper wires.

4)The resistance of the 3 wires must be the same.

NOTE:

1)Do not run input wires with power cables.

2)High line resistance can cause measurement errors.

3)When shielded cable is used, ground it at one end only to avoid ground loop currents.

4)The input impedance is equal to: Less than 5 Ω for 20 mAdc input Greater than 1 MΩ for 60 mVdc input

Greater than 400 KΩ for 5 Vdc and 10 Vdc input

B) Logic Input

This input is used as a remote reset.

Safety note:

-Do not run logic input wiring with AC power cables.

-Use an external contact with a contact rating greater than 0.5 mA, 5 Vdc.

-The instrument needs 100 ms to recognize a contact status variation.
