4.3.3 CHANNEL/ALARM CONFIGURATION (Cont.)
Example: A type J thermocouple is used to measure a temperature range of 100 to 200 degrees Celsius.
This thermocouple output is transmitted to the recorder by a 4 to 20 mA transmitter, for display as an ef-
fi ciency value between 0 and 100%. In such a case, the following values would be set up:
Input type = milliamp
Input low = 4.0
Input high = 20.0
Shunt = 250 Ohms
Lin Type = Type J
Range Low = 100
Range High = 200
Range Units = ˚C
Scaled =
Scale low = 0.0
Scale high = 100
Scale units = %
Note: The following description shows all possible fi elds. The recorder itself edits the list and
shows only those fi elds appropriate to the setup so far. For example, the ‘Shunt’ fi eld appears only
for mA input type.
CHANNEL NUMBER
The current channel and its descriptor are displayed. Touching the window area allows another channel
to be selected for confi guration. Alternatively, the right and left arrow keys at the bottom of the screen
can be used to increment and decrement, respectively, the channel number.
VALUE
Shows the current value of the channel, together with either ‘Unadjusted’ or the date and time of channel
adjustment (
section 4.6.4
).
INPUT TYPE
According to the options available, one of the following may be selected as input type: thermocouple,
millivolt, Volt, milliamp, RTD, Ohms, Digital (not channel 1, 7 etc.), Modbus Comms Input, Ethernet/IP
Comms Input, Test or Master Comms.
Select Modbus Comms Input if the channel is to be written-to via Modbus. Use Ethernet/IP if the channel
is to be written-to by an Ethernet/IP client. Master Comms must be selected if this channel is to be read
from another instrument.
Note: See
section 4.3.16
for details of Master Comms,
section 4.3.21
for details of the EtherNet/IP
option and
section 4.3.15
for Modbus comms (Connections).
LIN TYPE
The following linearisation tables are available as standard:
Linear, square root, x3/2, x5/2, UserLin1, UserLin2, UserLin3, UserLin4 (see
section 4.3.9
for user lin-
earisations)
Thermocouple types B, C, D, E, G2, J, K, L, N, R, S, T, U, NiMo/NiCo, Platinel, Ni/NiMo, Pt20%Rh/
Pt40%Rh
Resistance thermometer (RTD) types Cu10, Pt100, Pt100A, JPT100, Pt1000, Ni100, Ni120, Cu53.
For input ranges, accuracies etc. associated with the above thermocouple/RTD tables, see
Annex A
