Note

Any old alarm status/limits, Review array values, or scaling parameters are automatically cleared whenever you change a channel’s function.

Setting Alarm Limits and Mx+B Scaling Values

Alarm limits and Mx+B scaling values are set in a manner very similar to that used for the channel function. Begin by pressing either of the following buttons:

ATo begin alarm limits settings for this channel.

BTo begin scaling value settings for this channel.

The setup sequences are briefly discussed below. Refer to Chapter 3 for more details about these and other instrument parameters.

Alarm Limits

The menu for setting alarm limits allows you to set up both setpoints (Sand T). After choosing a setpoint, the following settings must be made:

∙The alarm sense HI, LO or OFF.

∙The limit value (sign and number).

∙The decimal point location.

∙The value multiplier (m, x1, k, M).

Use G, D, Hand Jto cycle through the selections at each setting. Then press E to accept your choice and move on to the next setting.

For example, to set a high limit of +5.35 for alarm Son channel 7, do the following:

1.Select channel 7 by pressing Gor D.

2.Press Ato begin alarm setting for channel 7. "LIMIT" and S(for alarm limit 1) now appear in the display. Press EEto accept that you are setting up alarm limit 1.

3.Use the arrow buttons to select "HI". Then press E.

4.Now use the arrow buttons again to set "+53500". Press Hor Jto move between digits. Press Gor Dto select the value for each digit. (Ignore the decimal point). Press Eto accept these digits.

5.Use the arrow buttons to select the decimal point position ("+5.3500"). Then press Eto accept this position.

6.Next, use the arrow buttons again to select the multiplier ("x1"). Press Eto accept this multiplier and save alarm limit 1.

7.Limit Sfor channel 7 is now set for a high value of +5.35. Continue pressing E to step through alarm limit 2 and return to the Inactive Mode. Or, press Dto immediately return to the Inactive Mode.

Pressing Dwhile partway through setting limit Sundoes any changes entered thus far for limit S, returning the instrument to Inactive Mode. Pressing Dwhile partway through setting limit Tcancels entries made thus far for limit T, but does not affect any changes already made to limit "1".
