4.3.6 Sensor Parameters (continued)
Below are some definitions of terms used in the Sensor Parameter pages.
Sensor Name:
a text field shown on the “Read Sensor” page.
TC Type:
a list of thermocouple types to select from
J, K, T, E, R, S, B, C, N,
and
L (J Din).
(See
Figure 12
).
Sampling Rate:
the number of readings per second. The options are:
2, 4, 8,
and
12
;
if the higher sampling rate is selected, you’ll have a lower accuracy. (See
Figure 12
).
Remote End Char:
The default value is 0D (Hex representation of <CR>). This means
that the iServer sends <CR> after each temperature value. This will be done in
Continuous mode.
This is how the data will appear on the host with 0D
assigned:
TA71.34F
TA72.48F
TD-1.19F
If the end character, for instance, is 20 (Hex
representation of space), the data will then appear as:
TA71.34FTA72.48FTD-1.19F
If nothing is set for the “Remote End Char” field, the
iServer will then forward the data to the LAN with no
characters followed.
Remote Display Format:
This determines the data
format sent by the iServer to a remote network node
(e.g. iLD Display)
Example: If Channel 1 shows temperature of
71.34
°
F
,
the
TA71.34F
will be seen on the remote display. If no format is specified (blank), there
is no reading sent out. If temperature is
75.7
and
T00.0F
is used in temperature setting,
the remote site will show
T75.7F
.
This format setup was originally made for the iLD Display, which has four or six LEDs.
For six LEDs,
T00.00F
format, and for four LEDs,
00.0F
format are appropriate.
Offset:
Since the sensing probe is solid state electronics, there is no need for
calibration. If it’s determined that the readings are slightly off, the user can manually
assign numerical values to adjust the readings for temperature values. The unit must be
in degree C. The Offset value can either be a positive or negative number
Cold Junction:
The options are
Disable
and
Comp_1
for sensor 1 and
Comp_2
for
sensor 2. Selecting Comp_1 or Comp_2 will allow you to adjust (calibrate) that sensor in
reference to 0
°C environment. Cold Junction Compensation is done for type K thermocouple
for both sensors before the product is shipped. If a different type of thermocouple is used, we
strongly recommend to perform Cold Junction Compensation on that sensor.
Input 2:
The options are
Enable
and
Disable
for the second thermocouple sensor only. If
it is disabled the thermocouple #2 and the “Differential” value will be shown as “N/A” on
the “Read Sensor” and “Chart” pages.
If the second thermocouple channel is not used, it is strongly recommended to
disable “Input 2”, for faster operation.
