Faults are not stored; therefore, they are immediately
removed if power is cycled. If the problem causing the faults
still exists, however, faults will be displayed again after
power is re-applied and a period of time elapses during
which the diagnostic system re-detects them. The
exception to this rule is the calibration failure. When a
calibration fails, no corrupt data is stored. Therefore, the
system continues to function normally on the data that was
present before the calibration was attempted.
After 30 minutes or if power to the transmitter is cycled, the
failure for calibration will be cleared until calibration is
attempted again. If the problem still exists, the calibration
failure will re-occur. Press ENTER to initiate view of the
highest priority failure. The display will automatically return
to normal after a few seconds.
Sim
Out
The Sim Out function allows the user to simulate the
conductivity level of the instrument in the user selected
display range. The user enters a conductivity value directly
onto the screen, and the output responds as if it were
actually receiving the signal from the sensor. This allows the
user to check the function of attached monitoring equipment
during set-up or troubleshooting. Escaping this screen
returns the unit to normal operation. Press ENTER to initiate
the user entry mode, and the right-most digit of the value will
flash. Use arrow keys to modify desired value.
The starting display value will be the last read value of the
input. The output will be under control of the SIM screen
until the ESC key is pressed.
Note:
If the HOLD function is engaged before the Sim Output
function is engaged, the simulated output will remain the
same even when the ESC key is pressed. Disengage the
HOLD function to return to normal output.
NOTE:
If the HOLD function is engaged before the
Sim Output function is engaged, the simulated output
will remain the same even when the ESC key is pressed.
Disengage the HOLD function to return to normal
output.
