PC-Programmable MODBUS
Temperature Transmitter
Running Average Filter–
This function is for
filtering the input signal. The TMZ provides this filter
with a user-selected range between 1 and 16. Factory
default is 4.
Note:
A higher Running Average Filter setting provides
smoother output transitions however, reduces
response time. Conversely, a lower setting provides
a faster response time, but may seem more
unstable.
Input Filter–
This setting is used to configure the
input filter. This filter is designed to reduce the effects
of mains-induced noise. The input filter frequency
value should be set to the frequency of the local AC
supply-either 50Hz or 60Hz.
Note:
Once you have configured all parameters, download
to the unit by selecting “Download” in the Transfer
dropdown menu located in the Status Bar. You may
also download by clicking the button in the
Tool Bar.
You may also use the
Quick Set
feature to configure
your
Input
parameters and download the settings.

Input Range–
Allows you to set your “Upper
Range Value” (URV) and “Lower Range Value” (LRV)
depending upon the input configuration and range
chosen in the
Input Type
section.
Note:
The upper and lower range values will, by default, be
set to the maximum range determined by input type
with the exception of thermocouple and RTD inputs,
which have fixed range values user cannot change.
Temperature Measurements–
Select the unit in
which you wish your
Input Range
displayed. Choose
from Deg C, Deg F, Kelvin or Deg R.
Broken Wire–
Allows the TMZ to continuously
test the integrity of your sensor wiring by sending
out random microamp pulses during operation. If a
problem is detected, a message is displayed in the
Device Status
box.
