Chapter 3. St<strong>and</strong>-Alone <strong>STX</strong> Analog Calibration <strong>and</strong> Setup<br />

Remote Tare<br />

The remote tare feature allows you to tare or<br />

‘zero’ a vessel. Remote tare is useful when<br />

you want to monitor how much material is<br />

added to or removed from the vessel from a<br />

given point. The effect is as follows:<br />

• If the <strong>STX</strong> current output is in Net Mode,<br />

the current output will correspond to the<br />

change in weight since the last time the<br />

vessel was tared, rather than to the total<br />

weight in the vessel.<br />

• (if <strong>STX</strong> installed in or serially communicating<br />

with MVS) If the MVS-<strong>STX</strong> display<br />

is set to Net (by pressing the Net/Gross<br />

Key), the display will correspond to the<br />

change in weight since the last time the<br />

vessel was tared, rather than to the total<br />

weight in the vessel. If setpoints <strong>and</strong>/or<br />

current outputs are set up based on net<br />

weight, their activation will correspond to<br />

the change in weight since the last time<br />

the vessel was tared.<br />

• (if <strong>STX</strong> serially communicating with PC,<br />

ROPE, etc.) Any serial communications<br />

related to the Net weight will correspond<br />

to the change in weight since the last<br />

time the vessel was tared.<br />

Refer to the referenced drawings in<br />

Appendix H. To activate the remote tare:<br />

• St<strong>and</strong>-Alone (TI-SP.<strong>STX</strong>-02): Short IN<br />

<strong>and</strong> +5V on TB1 on the <strong>STX</strong> PCB<br />

together for 1 second with a dry contact.<br />

• St<strong>and</strong>ard 19” Rack (TI-SP.<strong>STX</strong>-03) or<br />

MVS-<strong>STX</strong> (TI-MVS.<strong>STX</strong>-01): Short<br />

Digital In <strong>and</strong> +Vout on TB2 on the<br />

Termination PCB together for 1 second<br />

with a dry contact.<br />
