Users Manual

5.Using a digital multimeter (DMM), verify that all digital outputs (0-7) are in the OFF or HIGH state. This is done by connecting the low or common of the multimeter to the ground test lead and the high of the multimeter to the digital output and verifying a voltage greater than +3.8V dc.

6.Using either a terminal or a computer running a terminal emulation program, set up Hydra Series II to turn Digital Outputs ON (LOW state).

In sequence send the following commands to Hydra Series II and measure that the correct Digital Output line transitioned LOW measures less than+0.8V dc.

DO_LEVEL 0,0 <CR>

Ensure that output 0 measures a LOW state. DO_LEVEL 1,0 <CR>

Ensure that output 1 measures a LOW state. DO_LEVEL 2,0 <CR>

Ensure that output 2 measures a LOW state. Repeat the command for all eight outputs.

7.Set up Hydra Series II to turn Digital Outputs OFF (HIGH state).

In sequence send the following commands to Hydra Series II and measure that the correct Digital Output line transitioned HIGH measures greater than +3.8V dc.

DO_LEVEL 0,1 <CR>

Ensure that output 0 measures a HIGH state. DO_LEVEL 1,1 <CR>

Ensure that output 1 measures a HIGH state. Repeat the command for all eight outputs.

Digital Input Test

1.Perform the DIGITAL OUTPUT TEST steps 1 through 5.

2.Using either a terminal or a computer running a terminal emulation program, set up Hydra Series II to read the Digital Input lines.

Send the following command to Hydra Series II: DIO_LEVELS? <CR>

Verify that the returned value is 255.

Note

The number returned is the decimal equivalent of the Digital Input binary word (inputs 0 through 7’s status). See Table 7-7 to determine if the number returned corresponds to the bits jumpered to ground in this test.

3.Jumper input 0 to ground by connecting the ground test lead to input 0’s test lead. Then send the following command to Hydra Series II:

DIO_LEVELS? <CR>

Verify that the returned value is 254.

4.Disconnect input 0 from ground then jumper input 1 to ground.
