Table 2-1. Display Annunciators (cont)
"1" Lit when alarm limit 1 is being defined. Also lit when displaying a measurement
value (LAST, Monitor) which has exceeded alarm limit 1.
"2" Lit when alarm limit 2 is being defined. Also lit when displaying a measurement
value (LAST, Monitor) which has exceeded alarm limit 2.
HI, LO Identifies alarm limit sensing (high or low) during channel configuration. At other
times, identifies an alarm condition.
REVIEW Indicates that review data is being displayed (used in conjunction with the MIN,
MAX, and LAST annunciators).
MIN, MAX Indicates that the displayed value is the minimum (maximum) value measured on
this channel.
LAST Indicates that the displayed value is the most recent scan measurement taken on
this channel.
PRN Indicates that the autoprint function is enabled (to send readings to a printer) or the
memory storage function is on (to store readings in internal memory.) Internal
memory is available with Hydra Data Logger only.
F Bright when memory storage is full, dim when memory storage is nearly full. Hydra
Data Logger only.
EXT Indicates that external triggering (on the rear panel) is enabled.
TR Indicates that internal triggering (from the monitor alarm) is enabled. Also used with
