Other Alarms
• OPEN thermocouple: A thermocouple channel that is OPEN (no
thermocouple connected) will cause an OPEN alarm.
OPEN will be displayed instead of a temperature when that
channel is displayed.
Check thermocouple connection, wiring to the thermocouple, or
replace the thermocouple.
If the channel is not used, disable the channel (see How to Enable/
Disable channels, page 30).
• UNDER alarm: If the instrument detects a reading indicating a
temperature below the operating range of the thermocouple type
an UNDER alarm occurs.
UNDER will be displayed instead of a temperature when that
channel is displayed.
• OVER alarm: If the instrument detects a reading indicating a
temperature above the operating range of the thermocouple type
an OVER alarm occurs.
OVER will be displayed instead of a temperature when that
channel is displayed.
• LOG FULL alarm: 4,680 12-Channel records can be stored in
memory. A record is stored in memory manually by pushing
STORE, or automatically according to the log rate setting in the
menu.
During a LOG FULL alarm LOG and FULL alternate in the display.
During a LOG FULL alarm you can:
• RECALL - scroll through the logged readings.
• PRINT - print the logged readings.
To clear (erase) the memory: push CLEAR then push LOG.
• Instrument errors: Various hardware errors can also cause an
alarm such as an A/D error, EEPROM verify error, flash write error,
etc. The entire display will flash the alarm message. See Error
Messages, page 62.
Normal display updates stop until the alarm is acknowledged.
Other updates (scanning, printing, other alarms, logging) continue
without interruption.
