2.11.4 Using CONFIGURE CHAN to configure
channels
The CONFIGURE CHANNELS menu allows you to:
• Select measurement functions for internal scanner card
channels, and define which channels to use when scan-
ning.
• Select measurement functions and the number of chan-
nels in an external scanner used with the Model 2002.
• Define, save, and restore an alternate measurement
function which can then be assigned to specific chan-
nels.
Table 2-39 summarizes the CONFIGURE CHANNELS
menu structure, which is discussed in detail in the following
paragraphs. Again, see paragraph 2.3.4 for more information
on navigating menus.
The CONFIGURE CHANNELS menu is displayed by
pressing CONFIG and then CHAN.
INTERNAL CHAN
The INTERNAL-CHANS selection allows you to set the
measuring function for each of the internal scanner card
channels. When this selection is made the currently selected
function for each channel is displayed.
Changes are made by placing the cursor on the desired chan-
nel and using the RANGE
▲
and
▼
keys to select the desired
measurement function:
DCV: DC volts
ACV: AC volts
Ω
2W: 2-wire ohms
Ω
4W: 4-wire ohms
FRQ: Frequency
TMP: Temperature
ALT: alternate function (see below)
JN1...JN5: Reference junction type
--- : None
Ω
4W function:
The
Ω
4W function is valid only for chan-
nels 1-5 for the Model 2001-SCAN and channels 2-5 for the
Model 2001-TCSCAN. If selected, “PRD” (paired) will be
shown on the corresponding paired channel (6-10 for the
Model 2001-SCAN and 7-10 for the Model 2001-TCS-
CAN). Once
Ω
4W is selected for a valid channel, changing
the assignment to a different function will de-assign the
paired channel and change the function to “---” (none).
TMP function:
The TMP function is valid for the same
channels as the
Ω
4W function if the temperature sensor is a
4-wire RTD type. If a 2-wire RTD type is used, channels 6-
10 could be assigned to the TMP function, but if the sensor
type is later changed to a 4-wire RTD, any channel from 6-
10 will then be set to “---” (none). Thermocouple TMP mea-
surements, using the Model 2001-TCSCAN, can be assigned
to channels 2-10.
