4. Verify Accuracy Insert the RTD and a mercury thermometer in a room-
temperature bath. Allow 20 minutes for thermal stabilization. The value
displayed on the mercury thermometer should equal the value in the Spy
Window +0.25°C (2640A) or +
0.80°C (2645A) plus sensor inaccuracies.
5. Close Spy Window.
Digital Input/Output Tests 6-24.
The Digital Input/Output Tests check the eight Digital I/O lines on the DIGITAL
I/O connector for output and input functions.
Digital I/O Output Test 6-25.
This test checks the Digital I/O lines when used as outputs.
1. Open Spy Window Select the Spy command from the Utilities menu. Select
01DIO. Click OK to open the Spy window.
2. Verify Digital I/O Output for all Unset Lines The Spy window summarizes
the 8 DIO binary lines as a decimal equivalent, i.e., 255 for the present
condition of all lines unset (11111111).
3. Measure DIO Lines Using a digital multimeter, measure the output of each
DIO line, referenced to the GND line, for a voltage greater than +3.8V dc.
4. Close Spy Window.
5. Configure Channels 1 to 8 for Volts DC In NetDAQ Logger, configure
channels 1 to 8 for Volts dc, 3V range. (See “Configuring Analog Channel
Functions" in Chapter 3 of this manual.)
6. Configure Channels 1 to 8 for Alarms In NetDAQ Logger, configure each
channel 1 to 8 for an Alarm 1 with Alarm Sense=LO, Alarm Value=1 and
Digital Outputs assigned as below. (See "Configuring Alarms" in Chapter 3 of
this manual.)
Channel 1 - Digital Output DO0
Channel 2 - Digital Output DO1
Channel 3 - Digital Output DO2
Channel 4 - Digital Output DO3
Channel 5 - Digital Output DO4
Channel 6 - Digital Output DO5
Channel 7 - Digital Output DO6
Channel 8 - Digital Output DO7
7. Verify Channels and Alarm Configuration After Steps 5 and 6 are
completed, the portion of the Main Window for channels and alarms
configuration will appear as shown below.
