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

Hydra Series II should now display a totalizer count of 2.

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 changed from its maximum count (65535) to zero (0) and has set the Totalize Overflow bit in the Instrument Event Register.

Totalizer Sensitivity Test

1.Perform the Totalizer Test and ensure that it is operational.

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

3.Ensure that Hydra Series II is still in the totalize display mode. If not, press the O button. Reset the totalizer count shown on the display by pressing Hydra Series II’s front panel Kbutton followed by O(ZERO) button.

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

4.Connect the output of the signal generator to the SUM and GROUND terminals.

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

Hydra Series II’s display should now show the totalizing value incrementing at a 10 count per second rate.

Dedicated Alarm Output Test

The Dedicated Alarm Output Test verifies that Alarm Outputs 0 through 3 are functioning properly. Because this test is dependent on voltage readings, the Accuracy Verification Test for channel 0 and the Channel Integrity Test for channels 1 through 3 should be performed if voltage readings are suspect.

1.Switch OFF power to the instrument and disconnect all high voltage inputs.

2.Remove the Alarm Output eight-terminal connector module from the rear of Hydra Series II and all external connections to it. Connect short wires (to be used as test leads) to the GROUND and 0 through 3 terminals. Leave other ends of wires unconnected at this time. Reinstall the connector.
