6.3Reset

6.3.1The instrument can be reset without losing calibration or any of the stored values by pressing and releasing the S9 reset button (located at the bottom of the board near the center) This action is equivalent to turning the power off and on.

6.4Output Hold

6.4.1It may be useful during some system maintenance procedures to place the relay and analog outputs on hold. To accomplish this simply press CALL. To return to on line operation press RUN.

NOTE: To safeguard against the operator forgetting to press RUN the instrument will automatically go back on line ten minutes after the last button was pressed provided this feature has been enabled by placing DIP switch No.7, Bank S1, in the ON position.

7.0UTILITY MENU

7.1Utility Menu Functions

7.1.1The Utility Menu enables authorized personnel to perform the following:

Adjust the temperature output range.

Adjust the offset and span of the 0-1 mA/ 0-5 Vdc output

Adjust the offset and span of the 4-20 mA output

Perform the altitude compensation

7.2Access to Utility Menu

7.2.1The Utility Menu is protected by password. To access the Utility Menu press and hold both RUN and ENTER for five seconds until the PASSWORD LED illuminates. The RUN LED will flash to warn that Utility Menu is in use. Now with the arrow keys make the display read the password, "7". Press ENTER.

7.2.2The Utility Menu is entirely separate from the Operation Menu but uses the same LED display. Press CALL to step through the menu items.

Below is the cross-reference between menu items:
