There are eight amplifier keys located on the right side of the front panel. Each key supports two channels via toggle. For

example, the first amplifier key toggles between Channels 1 and 9. When a channel is selected, several choices for

channel settings are available:

[SET RANGE]

[SET OFFSET]

[DC / GND]

[PK - PK / RMS]

[SETUP DSP / FILTER]

[SETUP USER SCALING]

[COPY AMPLIFIER]

[ADVANCED]

See exercises in Section 9 for details on using the Amp keys.

NOTES:

At this point, you can run the chart with your signals. Press the [MODE] key and run the chart you set up. To stop the

paper, press the [RUN / HALT] key. You can also freeze the display and use two cursors (A, B) to make time and

amplitude measurements. You can print the screen or even save the screen image to your Zip disk.

It is recommended for each channel used that its grid be turned ON:

[SYS] [CUSTOMIZE CHART] [CHANGE GRID]. Under this menu, you can

change the size, location and appearance of each grid.

Also, each channel used should have its trace drawn on the chart:

[SYS] [CUSTOMIZE CHART] [CHANGE WAVEFORMS]

[PEN up] or [PEN down].

Lastly, there are sixteen text buffers that are defaulted to write a channel number.

Although the buffers are independent of the grid and waveform, it is typical to

associate one text buffer for each channel. It is recommended to turn off the

buffers for those channels not used: [SYS] [EDIT LABELS / TEXT].

6. AMPLIFIER SETTINGS

Sets full scale value for the channel.

Sets the zero offset from the center of the channel.

Toggle between grounding and ungrounding the channel.

This does not ground the signal input itself!!

Toggle between peak-to-peak or RMS value.

Select type of filter (notch, low pass, high pass, band pass, etc.)

Assign engineering units to the channel values. Includes offset compensation.

Copy part or all of a channel setup to another or all other channels.

- Attenuator settings for selected amplifier type.

- Calibrate channels using module or manual method.

- Change amplifier type (single-ended, differential, temperature, DC bridge).

For each of the four amplifier types, there are different attenuator ranges. If you

can't get the desired range and offset, you need to select a different attenuator.

If you will use user scaling to assign engineering units, it is recommended to first

set up your channel in terms of voltage and verify you signal. Then, assign your

units.

The upper and lower bounds of the channel can be printed in the latter part of the

text buffer for the channel: [SYS] [CUSTOMIZE CHART]
