(e)

The bottom line contains the Snapshot operating information. The letter T indicates the number of

the frame that contains the trigger. The letter C indicates the number of the frame you are

CURRENTLY looking at. Use the LEFT and RIGHT arrow keys to increase or decrease the

number of CURRENT frame. Observe the data as you move from one frame to the next. The

display will show you the changes that took place. If you want to jump immediately to a specific

frame, use the numeric keys to input the desired frame number. The numbers you input will replace

the dashes after the GOTO. When you press ENTER, you will jump directly to the specified frame.

NOTE

If you tell the DDR to GOTO a stream number larger than the highest one stored, the

dashes will reappear.

If you plan to print out the data just recorded, write down the frame numbers of the data

streams you want to print. You will need to know these frame numbers when you enter the

Print function.

(f)

Data update rate. The data displayed by your DDR is updated at specified intervals. You can

specify how often you want this to happen using Data Update Rate.

(g)

The amount of time that elapses between updates is called the delay. This can be varied from 0.0

to 9.9 seconds. Use the numerical keys to input a NEW delay rate. When this rate is displayed,

press ENTER. The DDR will return to the Snapshot menu.

(12)

Contrast adjust. Contrast refers to the darkness of the readout letters and numbers when compared with

the background. Under some viewing angles and at various air temperatures, you will be able to see the

readout better if you adjust contrast.

NOTE

If you are using the DDR in direct sunlight, the heat of the sun may affect contrast. As

temperature goes up, the display may darken. If so, adjust contrast.

To adjust contrast, select the Contrast Adjust function.
