Electro-Chemical Devices (ECD) T80 - Manual (Page 24)

Any two solutions can be used for AUTO calibration however if solutions other than those listed above
are used for calibration then the calibration values must be entered manually.
 STAND is standardization, a single point calibration. Standardizations are typically used to adjust the
process reading to agree with a laboratory determined “grab sample” reading.
 MANUAL is a data entry screen. Manual calibration allows the user to enter a concentration with the
corresponding mV value and a slope for an electrode. Laboratory generated calibration data for an
electrode can be input to a remote analyzer where calibration is difficult or impractical.
 TEMP allows the displayed temperature to be trimmed to agree with actual
process temperature.

Four options are available in the Configure Menu, XMTR, SENSOR, LOAD DEFAULT
and Dampen.
 XMTR enters the Transmitter Configuration menu.
o
LCD access the Display Configuration Menu
 SETUP adjust screen lighting characteristics
• Temp. Choose °C or °F
• CONT adjust Contrast
• BACK LIGHT adjust Backlight Timeout, from always ON to OFF after 10 minutes
 GRAPH provides the choice of which Graph style is displayed on the Home screen.
• LINE , Moving average, vertical scale set to 0-100%
of the 4-20 mA output and user defined time scale
• GAUGE, Current reading 0-100% of 4-20 mA range
• BAR, Current reading 0-100% of 4-20 mA range
 LABELS
• TAG, Enter up to 2 lines x 16 characters, example,
Name, tag #... Displayed in INFO screen
• TAG ON, Turn TAG ON/OFF, adds TAG to Main
Display Sequence, DATA → mV → GRAF → TAG →
DATA
• POP UP, Turns ON/OFF, the double tap HOME Screen pop up memo
• SENSOR, Enter up to 2 lines x 16 characters
o
OUTPUT access the Output Configuration Menu
 4-20 mA configure 4-20 mA output (PV or Temp or More)
• RANGE Enter 4 mA value and 20 mA value
• CAL Trim 4.00 mA output and 20.00 mA output
• FAULT Choose fault condition 3.5 mA, 22 mA, None
