3.2.9 Range
Note: See
section 4.4.3
instead, if the 'Channel tags' option is fitted.
This section allows the configuration of the input channels to be entered. Figure 3.2.9 shows the top level range con-
figuration menu for three cases:
1. Input type = thermocouple or RTD; Linearisation = TC or RTD type.
2. Input type = V, mV, mA or ohms; Linearisation type = linear or square root and
3. Input type = V, mV, mA or ohms; Linearisation function = Thermocouple or RTD type.
This last combination is used with transducer transmitters which do not incorporate their own linearisation tables.
Notes:
1.
Channel one must not be used whilst configured as 'Ohm' or 'RTD' unless the CJ sensor has been disconnected
(
figure 2.2
), or gross measurement errors will occur. When the CJ sensor disconnected, no other input channel
should be configured as T/C unless it uses an external CJC.
2.
The background (PV) display will show 'brng' (bad range) if any one or more of the following obtain:
a.
Input range low
≥
Input range high
b.
Linearisation range low
≥
Linearisation range high
c.
Scale low = Scale high
d.
Hardware capabilities are exceeded
e.
Linearisation type is inappropriate to the rest of the configuration
