10. Calibration Due Indicators
The CAL INSTRUMENT indicator will flash on the display as a warning 30 days before instru-
ment calibration is due. To acknowledge this warning and turn off the flashing indicator,
select the menu item CALrt and change the first digit from a 1 to a 0. The CAL INSTRUMENT
indicator will then disappear until the 30-day period has expired, after which it will reappear
as a steady indication. Once it has started flashing, the CAL INSTRUMENT indicator will
continue to flash until it has been acknowledged, even after the 30 days are exceeded.
The CAL SENSOR indicator functions the same as the CAL INSTRUMENT indicator, except
that it is acknowledged by changing the second digit of CALrt from a 1 to a 0. The operation
applies to the TEDS sensor that is actively connected to the SSI unit. If a TEDS sensor is
not connected or Plug and Play is not selected, the CAL SENSOR indicator does not appear.
The CAL INSTRUMENT and CAL SENSOR indicators may be enabled or disabled by the
3
rd
digit of the tArE menu item. See page 32.
