f.RESET MAX CELL T

Refer to Figure 3-12. The transmitter tracks the maximum cell temperature obtained. Use this screen to reset the maximum cell temperature attained value to the current cell temperature. Press ENTER to begin editing. Use the arrow keys to select and change the value (Y/N). Then, press EN- TER to accept the value. Pressing NEXT displays the SET O2 FILTER TIME screen.

g.SET O2 FILTER TIME

Refer to Figure 3-13. In some applications, it is beneficial to dampen the raw O2 signal coming from the cell. Use this screen to enter the amount of time it will take the O2 to reach 90% of the new reading. Press EN- TER to begin editing. Use the arrow keys to select and change the screen value to the O2 filter value (in seconds). Enter a value between 0 and 300 seconds and press EN- TER to accept the value. Press NEXT to access the TRIM 4 mA? screen.

h.TRIM 4 mA?

Refer to Figure 3-14. Use this screen to trim the 4 mA value of the 4-20 mA output.

Before trimming the 4 mA value, you must break the loop to add the amme- ter. Power down the unit, connect the ammeter in series with Model 5081 Transmitter terminals 15(-) and 16(+), power up the unit, and return to the TRIM 4 mA? screen.

Press ENTER to begin editing. Use the ar- row keys to select and change the screen value to the value displayed on the installed ammeter. Press ENTER to accept the value. After the value is entered, the unit calibrates itself to ensure it outputs 4 mA. Both the display and the ammeter will dis- play 4 mA. Pressing EXIT returns to the ini- tial TRIM 4 mA? screen, and pressing NEXT displays the TRIM 20 mA? screen.
