5.Press the TOTAL button on the front panel of Hydra Series II. Assure Hydra Series II displays a 0 value.

6.Jumper output 0 to the Total () input by connecting the () terminal test lead to output 0’s test lead.

7.Using either a terminal or a computer running a terminal emulation program, set up Hydra Series II to toggle (turn ON and OFF) Digital Output 0.

In sequence send the following commands to Hydra Series II and assure Hydra Series IImeasures and displays the correct total value:

DO_LEVEL 0,0 <CR> DO_LEVEL 0,1 <CR>

Assure Hydra Series II displays a totalizer count of 1.

8.Again in sequence send the commands: DO_LEVEL 0,0 <CR> DO_LEVEL 0,1 <CR>

A totalizer count of 2 should now be displayed.

9.Repeat step 8 for each incremental totalizing count.

10.Set the Hydra Series II’s totalized count to a value near full range (65535) and test for overload.

Send the following commands to Hydra Series II: TOTAL 65534 <CR>

DO_LEVEL 0,0 <CR> DO_LEVEL 0,1 <CR>

A totalizer count of 65535 should be displayed.

11.Send:

DO_LEVEL 0,0 <CR> DO_LEVEL 0,1 <CR>

Hydra Series II’s display should now read "OL". This indicates that the counter has been overrun.

Totalizer Sensitivity Test

1.Perform the Totalizer Test and assure it is operational.

2.Remove the jumper connecting the () terminal test lead to output 0’s test lead.

3.Assure Hydra Series II is still in the total measuring mode. If not press the TOTAL button. Reset the totalizer count shown on the display by pressing Hydra Series II’s front panel SHIFT button followed by ZERO (total) button.

Hydra Series II’s display should now show a value of 0.

4.Connect the output of the signal generator to the () and ground J terminals.

5.Program the signal generator to output a 1.5V rms sine signal at 10 Hz.
