Setting the Scan Interval

Mx+B Scaling

The menu for setting Mx+B scaling values takes you through the following steps:

Set the M value (sign and number).

Set the decimal point location for the M value.

Set the multiplier for the M value (m, x1, k, M).

Set the B value (sign and number).

Set the decimal point location for the B value.

Set the multiplier for the B value (m, x1, k, M).

Use G, D, Hand Jto cycle through the selections at each step. Then press

EEto accept your choice and advance to the next step.

For example, to set an M value of 1.8 and a B value of 32 for channel 7, do the following:

1.Select channel 7 by pressing Gor D.

2.Press Bto begin Mx+B scaling setting for channel 7.

3.Use the arrow buttons to select "+18000". Press Hor Jto move between digits. Press Gor Dto select the value for each digit. (Ignore the decimal point). Press EEto accept these digits.

4.Use the arrow buttons to select the decimal point position ("+1.8000"). Then press Eto accept this position.

5.Next, use the arrow buttons again to select the multiplier ("x1"). Press Eto accept this multiplier.

6.Use the arrow buttons to select +00320. Then press EE.

7.Use the arrow buttons to select the decimal point position ("+0032.0"). Then press Eto accept this position.

8.Next, use the arrow buttons again to select the multiplier ("x1").Press Eto accept this multiplier as the multiplier for the B value.

Mx+B scaling is now set at 1.8x+32 for channel 7.

Pressing Dwhile partway through setting the M value undoes all changes entered thus far, returning the instrument to Inactive Mode. Pressing Dwhile partway through setting the B value cancels entries made thus far for the B value, but does not affect any changes already made to the M value.

Setting the Scan Interval

Press Ito set the scan interval. The latest value appears on the right display. The format of the display is H:MM:SS. Use Jand Hto move between digits. Use Gand

Dto select the new value for a digit. Values ranging from 0:00:00 to 9:99:99 are allowed. Press Eto accept the displayed value.

Set the interval to 0:00:00 for continuous scanning. If you set the interval to a value shorter than the time required to measure all channels, scanning effectively becomes continuous.
