COLD JUNCTION OFFSET CALIBRATION (C.J.OF)

The cold junction offset equals the actual temperature minus the reading temperature. You may compensate for any error due to cold junction on the TC input. You may perform this compensation in any temperature from 0░C to 40░C (or 32░F to 104░F), however we recommend you perform this compensation at 0░C (32░F) for best result. To do this, immerse the thermocouple hot junctions into a mixture of ice and water. Check the Reading Configuration bit R.1 of the "RD.CF" menu setting for the proper temperature units.

TO PERFORM THIS COMPENSATION, FOLLOW THESE STEPS:
1. Connect the thermocouple wire to the +S and -S input.

2. Press the MENU button until meter displays "CJ.OF".

3. Press the /DEV button. the meter displays the previous offset value with flashing 4th digit.

4. Press the /DEV button again. The reading temperature will be displayed (with no digit flashing).
    5A. If the value is okay, then press the MENU button. The display will show "STRD" and 0 value will be entered at the offset.
    B. If the value is not okay, then enter the actual temperature using the /DEV and /MAX buttons. Once you enter the accurate temperature, press the MENU button. The meter displays "STRD" and stores the offset value.
1. Temperature unit is either celsius or fahrenheit and will always be displayed at 0.1 degree resolution. The meter flashes corresponding LED.
 2. MAX/MIN offset value will be ▒25.0 ░C or 45.0 ░F. If offset the limit, the meter will flash "ER 3" and previous offset will not be changed.
LOCK OUT CONFIGURATION ("LK.CF")

Use Lock Out Configuration ("LK.CF") for the following:
    * To enable or disable setpoint changes
    * To enable or disable the RESET button in the run mode
To Enable or Disable the RESET button in the Run Mode
1. Press the MENU button until the meter shows "LK.CF" after ("C.J.OF").

2. Press the DEV button until the meter shows "RS.=E" (Default).

 3. Press the /MAX button to toggle between:
    "RS.=E" To enable the RESET button in the run mode (default)
     "RS.=D" To disable the RESET button in the run mode.
4. Once desired mode shows, press the MENU button to store the change. The meter returns to the run mode.

To Enable or Disable Setpoint Changes
1. Press the MENU button until the meter shows "LK.CF" (after "C.J.OF").

2. Press the /DEV button. The meter shows "SP.=E" (Default).

3. Press the /MAX button to toggle between:
    "SP.=E" To enable setpoint changes (default)
     "SP.=D" To disable setpoint changes
4. Once desired mode shows, Press the MENU button to store the change.

 To Enable DisplayÆs Program Version:
1. Press the MENU button until the meter shows "LK.CF" (after "C.J.OF").

2. Press the /DEV button. The meter shows one of the following:
    * "L.3=0" ôSETPTSö button will display setpoint values.
    * "L.3=1" "SETPTS" button will display "V.-03" which is the meter's current software version.
2. Press the /MAX button to toggle between the choices above.
3. Press the MENU button to store the changes.

 If your meter does not have the relay option, setpoint menu items above will not be available and SETPTS button will always display the meter's software version. These units will have +OL (overload) or +OPEN memory indicated by Alarm 1 & 2 LED displays. LEDs can be reset by pressing MENU then RESET button or by power OFF then ON. These units can not use analog output proportional to error from setpoint 1. under menu OT.CF, 0.3=P

TUNING PROPORTIONAL CONTROLLER

The Proportional Controller is not active unless your meter has analog output capabilities. The menu will display whether analog output is present or not. This function allows you to tune your controller provided you have analog output capabilities. Select proportional on Output Configuration (refer to Section 15-3) prior to tuning your controller. Include the meter in the process loop and turn on the meter. Allow enough time for the system to settle, then do the following.

1. Press the /DEV button. The meter momentarily shows "DEV" followed by a blinking value. This value is the deviation (error) between Reading and Setpoint 1 values. If this error is zero, your controller is tuned. If a value other than zero shows, proceed with step 2.

2.. Press RESET button. The meter shows "TUNE", tuning your controller and canceling any error. Once tuned, the meter shows "RST" and returns to the run mode.
Allow enough time for process to settle before proceeding with "TUNE" procedure. If any error happens during this procedure, meter will flash "ER 4" and abort the tuning. You have to restart the procedure.
 "TUNE" will be active if your meter has analog output capabilities.

 3. Press the /DEV button. Verify that blinking value is zero. If blinking value is not zero, repeat step 2.
