7.Output setup for normal outputs:

a. Move the cursor to the desired output setup and press Enter (F4).

b.Use the ￿ and ￿ arrow keys to move the cursor to the desired parameter. Press Edit (F4). Use the arrow keys to change the set- ting to the desired value and press Save(F4) to store the value.

Range: Choose 4-20 mA or 0-20 mA.

Dampen: Dampening averages the output current, thus smooth- ing out a noisy reading. Higher values provide more smoothing but increase the response time of the output.

Hold and Fixed Hold: If the analyzer is placed in hold, the out- puts will either remain at the last value or go to a fixed value selected by the user. The fixed value must be between 0 and 22.00 mA.

Fault: If the analyzer detects a fault, the output will signal the fault by going to a user-selected current between 0 and 22.00 mA.

For allowed values, see Table 5-1.

8.Hold setup.

a.Move the cursor to "Hold feature setup" and press Enter (F4).

b.Press Edit (F4). Use the ￿ to scroll through the choices: "Disable feature", "Enable feature", and "20 min timeout". If "20 min time- out" is selected, hold mode will automatically disengage after being on for 20 minutes.

NOTE

Selecting "Enable hold" or "20-min timeout" does not put the analyzer in hold. It only allows the user to put the analyzer in hold when the analyzer is in calibrate mode.

9.Using hold.

If hold was enabled in step 8 above, the hold screen will appear as soon as the user enters the Calibrate menu. To activate Hold, press Edit (F4). Use the ￿ key to change Off to On and press Save (F4). "Hold Mode Activated" will be displayed. Outputs and relays will go to the values programmed in step 7b.

"Hold Mode Activated" will continue to flash in the main display even after the user has left the Calibrate menu. To deactivate hold, enter the Calibrate menu and press Edit (F4). Use the ￿ key to change On to Off and press Save (F4). Press Exit (F1) twice to return to the main display.
