5.2.1.1 Clearing the Calibration security code from the display
The calibration security code automatically resets from “11” to “000” after you return to Measurement
mode, so you do not need to clear the security code from the display.
5.2.2 How to enter and change parameters in Advanced Setup mode
1) Press the ENTER key once. The upper display shows “000” and the lower display shows “S.Cd” to
prompt you to enter the Advanced Setup security code.
2) Press the ∆∆ or ∇∇ keys to scroll the display to Setup security code “22”. NOTE: Pressing the
ENTER key at a value other than “22” causes the controller to revert to the Measurement mode.
3) Press the ENTER key.
4) The upper display reads “tc”.
5) You are now in the Advanced Setup mode. See Section 7 for complete instructions. To return to
Measurement mode, press the ∆∆ and ∇∇ keys simultaneously (escape).
NOTE: If you want to view (not change) set up parameters, push the ENTER key when the security
code reads “000”.
5.2.2.1 Clearing the Advanced Setup security code from the display
After you have entered the security code and returned to the Measurement mode, the security code “22”
still appears on the display whenever you press the ENTER key. To conceal the security code, you must
manually reset the code. To clear the Advanced Setup security code from the display:
1) Press the ENTER key in the Measurement mode.
2) Set to any security code (not 11 or 22) and complete by pressing ENTER.
NOTE: When you enter the Calibration mode with code “11” or Advanced Setup mode with security
code “22”, the unit automatically enters into the HOLD mode until you return back to Measurement
mode. The HOLD annunciator is displayed at the upper left of the display. While on HOLD, the
current output is frozen and set point relays are deactivated.
