3-15
3. Select THERMOCOUPLE, then press ENTER. The
Model 2001/2002 will then display the thermocouple
setup menu:
THERMOCOUPLE SETUP
THERMOCOUPLE-TYPE REF-JUNCTIONS
4. Choose THERMOCOUPLE-TYPE, then press ENTER.
The list of supported thermocouple types will be dis-
played:
THERMOCOUPLE TYPE
JKTERSB
5. Select the thermocouple type to match those you are us-
ing, then press ENTER. Select REF-JUNCTIONS on
the displayed menu, then press ENTER. The Model
2001/2002 will display the following:
CONFIGURE REFJCNS
JCN1 JCN2 JCN3 JCN4 JCN5
6. Select the desired reference junction (for example,
JCN1), then press ENTER. The instrument will display
the following message:
REFERENCE JUNCTION#1
CONFIGURE ACQUIRE-REF-TEMP
7. Select CONFIGURE, then press ENTER. The following
will be displayed:
CONFIGURE REFJCN1
SIMULATED-TEMP REAL-JUNCTION
8. Select REAL-JUNCTION, then press ENTER. The in-
strument will prompt you to enter the reference junction
coefficient:
REFJCN#1=+00.20mV/°C
9. If necessary, set the displayed value to +200µV/°C
(+0.20mV/°C), then press ENTER. The unit will then
prompt you for the reference offset:
REFJCN#1=+54.63mV@°C
10. If necessary, set the offset to +54.63mV @ 0°C, then
press ENTER.
11. Press EXIT as necessary to return to the CONFIG TEM-
PERATURE menu, then select your UNITS, SPEED,
FILTER, and RESLN, as required.
12. Press EXIT to return to normal display.
Step 4: Configure channels
1. Press CONFIG-CHAN. The display will appear as fol-
lows:
SCAN OPERATION
1=DCV 2=DCV 3-DCV 4=DCV 5=DCV
2. Using the range and cursor keys, set the channel func-
tions as follows:
Channel 1: JCN1 (or JCN2-JCN5 if using those
junctions)
Channels 2-10: TMP for thermocouple channels, ALT
for RTD channels, --- for unused channels, or other
valid function if used.
3. After setting all channel functions, press ENTER to re-
turn to normal display.
Step 5: Configure and scan channels
1. From normal display, press CONFIG-SCAN. The in-
strument will display the following:
SCAN OPERATION
INTERNAL EXTERNAL RATIO DELTA
2. Select INTERNAL, then press ENTER.
3. Press SCAN, then follow the prompts to begin scanning.
See paragraph 3.4.4 for details.
3.8.4 IEEE-488 programming example (tempera-
ture measurements)
A programming example to scan channels is provided to
demonstrate how to perform temperature measurements us-
ing the Model 2001-TCSCAN card.
