LI5X Process & Temperature Meter Instruction Manual

Noise Filter Bypass (
byps
)
The meter can be programmed to filter small input changes, but allow
larger input changes to be displayed immediately, by setting the bypass
value accordingly.
If the input signal goes beyond the bypass value, it will be displayed
immediately with no averaging done on it.
The noise filter bypass value may be set anywhere from 0.2 to 99.9. It
corresponds to percentage of full scale for process inputs and to de-
grees Fahrenheit for temperature inputs.
Increasing the bypass value may slow down the display response to
changes on the input signal.
Serial Communications (
serl
)
The meter is already equipped with serial communications capability
using Flowline Proprietary Data Communication (PDC) protocol (stan-
dard). The Modbus RTU protocol is optional.
To communicate with a computer or other data terminal equipment, an
RS-232 or RS-422/485 adapter option is required, see
Ordering Infor-
mation
on page 3 for details.

When using more than one meter in a multi-drop mode, each meter
must be provided with its own unique address. The address may be
programmed from 00 to 99 for PDC protocol and from 1 to 247 for
Modbus protocol. The transmit delay may be set between 0 and 199
ms (see Serial Communication Adapter manual for more details).
The LI5X can also be connected directly to another LI5X meter with a
standard modular cable. This allows the user to copy all the settings
from one meter to another, using the
Copy
function.
