Figure 16
shows the TB82 in the MEASURE mode of operation.
Pressing the key at the far right, underneath the MENU icon, provides
access to all instrument functions.
Figure 17
shows the display after the MENU key has been pressed
once. The CALIBRATE menu can now be accessed by pressing the key
underneath the SELECT icon. If the MENU key is pressed
again
the
display will change to the next menu function choice, OUT/HOLD.
Pressing again will activate the CONFIGURE menu choice, and so on.
There are six MENU functions:
MEASURE
- Normal operational display
CALIBRATE
– Allows calibration of the conductivity and temperature sensors,
restoring calibration to the original factory values, tuning of the analog
output and also allows the ability to view or change the sensor’s slope and
offset.
OUT/HOLD
- Allows the output to be re-ranged, held or released (Analog version
only)
CONFIGURE
- Sets up how the transmitter operates
SECURITY
- Sets password protection to the CONFIGURE, CALIBRATE and
OUTPUT menus
DISPLAY
- Displays temperature in °F or °C, current output in mA, sensor input,
sensor group, concentration spike output status and software revision. Sets
what will be displayed under the secondary display when in the measure
mode.
Commissioning the Instrument
To commission the TB82:
1. Configure the instrument as required for the application.
2. Calibrate the sensor(s) as required (TB82EC and TB82TC).
3. Set up parameters on the receiving devices (e.g. PLC, DCS recorder) to properly recognize the TB82 outputs.
