Setting/Adjusting Electrical Damping - Siemens SITRANS P300 Operating Instructions Manual

To adjust the output current of the limit point, proceed as follows:
1. Create the reference pressure.
2. Set mode 3.
3. Adjust the output current of the limit point to the calculated value.
4. Save with the <MODE> key.
Setting limit point without digital display
You have a device with a cover without an inspection window and want to set the limit point.
To set the output current of the limit point to 20 mA, proceed as follows:
1. Create the reference pressure.
2. Press and hold down the <MODE> key.
3. Additionally, press the keys <UP> and <DOWN> simultaneously.
4. When you release the keys, the device automatically saves the value.
Adjusting limit point without digital display
You have a device with a cover without an inspection window and do not want to set the limit
point, but rather adjust it.
An ammeter is required to do this.
To adjust the output current of the limit point, proceed as follows:
1. Connect the ammeter to the test connector.
2. Create the reference pressure.
3. Press and hold down the <MODE> key.
4. Adjust the output current of the limit point to the calculated value with <UP> or <DOWN>
5. When you release the key, the device automatically saves the value.

Setting/adjusting electrical damping

The difference between setting and adjusting
The time constant of the electrical damping can be set or adjusted via the keys. Setting
means that the time constant is automatically set to 0 seconds. Adjusting means that the
time constant is adjusted in 0.1 second steps between 0 and 100 seconds. This electrical
damping also acts as the device's own basic damping.
