Configuring The Meter
4.13 RTD TEMPERATURE OFFSET. (T.OFF)
A new item has been added to calibrate for any offset error due to the RTD. This item will enable
you to compensate any temperature offset due to the RTD transducer:
OFFSET = ACTUAL TEMPERATURE - DISPLAY TEMPERATURE
1. Press the MENU button until "T.OFF" displays.
2. Press the
©
/DEV button. Previous offset value with digit 4 flashing will be displayed.
3. Press the
©
/DEV button again. Reading temperature will be displayed (with no digit
flashing).
4. a. If the value is okay, then press the MENU button. 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 the
¶
/MAX buttons.
5. Press the MENU button to store the changes.
a. Temperature unit is either celsius or fahrenheit and will always be displayed at
0.1 degree resolution. The meter flashes corresponding LED.
b. 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.
4.14 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. Select proportional on Output Configuration (refer to Section 4.8.3) 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.
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.
"TUNE" will be active if your meter has analog output and/or relay output capabilities.
3. Allow enough time for process to settle. Press the
©
/DEV button. Verify that blinking
value is zero. If blinking value is not zero, repeat step 2.
