The settings in detail:
Common Setting
The following is a common setting for all the channels:
Temperature Unit: °C / °F
Selects the temperature unit for all channels whose ‘Input
Type’ is defined as a thermocouple, i.e., TC-E, TC-J, TC-K, TC-
R, TC-S, or TC-T. In other words, this setting has no effect on
channels whose ‘Input Type’ is mV (or None).
Channel Settings
The following are individual settings for each channel:
Channel Name: ... (view only)
The user may assign a name to each channel.
This ‘Channel Name’ is actually a part of the ‘TCIC-Monitor
Settings’ (section 3.2.2.2); it does not reside in the card.
Though, for convenience's sake, the ‘Channel Name’ is shown
in the ‘Card Settings’ display, but restricted to ‘view only’.
Input Type: None / TC-E / TC-J / TC-K /
TC-R / TC-S / TC-T / mV
Each channel may be referred to as one of three main types:
* Channel not in use (‘None’).
In this case channel’s description (section 3.5.4) will show
‘Not in Use’ regardless of the input coming in that channel.
* Channel represents a thermocouple whose type is one of
the six supported ones (E, J, K, R, S, or T). The card
converts the sampled voltage to degrees (°C or °F), taking
into account the cold junction temperature. So, the
readings passed by the card are in degrees (°C or °F);
the TCIC-Monitor shows these readings (in the displays
and in the graph) in degrees either. In case the card
detects that no thermocouple is connected, it reports
it to the PC, so the TCIC-Monitor displays ‘OPEN’
in that case.
* Channel represents an indefinite source of voltage, to be
reported in millivolts (mV), not in degrees. In this case,
there is no ‘OPEN’ indication when a channel is
disconnected.
