Table 1-4. Annunciator Descriptions (cont)
Annunciator Description
M (mega) a multiplier for the displayed value, e.g., M½ for megohms. Also used when
defining alarm and Mx+B values.
R0 Lit when the ice point resistance is being defined for RTD measurements on the
displayed channel.
OFF Indicates there is no measurement function defined for the displayed channel; OFF
channels are skipped over when scanning. OFF is also used when defining an alarm
value to indicate that the alarm limit is to be ignored.
AUTO Indicates that autoranging is enabled for the displayed channel.
LIMIT Used with the [1] and [2] annunciators when you are setting an alarm limit value. Also lit
when displaying a measurement value (LAST, Monitor) which has exceeded an alarm
limit.
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 PC) or
the memory storage function is on (to store readings in a memory card).
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 EXT
when external triggering is enabled.
REM Indicates that the instrument is under the control of the RS-232 computer interface
(bright) or a front panel lockout option has been enabled (dim).
CAL Indicates that the instrument's internal calibration constants have been corrupted.
