• “High al.: ###.#C or F”: alarm high limit value in Cel-

sius (“C”) or Fahreneit (“F”) unit, depending on last
datalogger configuration (refer to HI92140 on-line-help
for details). If no high alarm limit was set by the user, then
the indication will be “High al.: -----C or F”.

• “ALARMS: ”: list of all active alarms,

as previously described (see “Alarm SMSs for HI142
dataloggers” subsection). If no alarm is active, then the

Information SMSs for meter connected to the digital input port

lated to present digital input status (close or open).
Here is a message example: “Freezer East Side; Digital Input;
Port is open; Rem msg:32”.

Note

If no information is available regarding an instrument because
it did not answer to HI504903 during last polling procedure,
then the following “Device not responding” string will appear
for field.

Note

If SMS sending is disabled through the external switch, then
HI504903 sends only the message: “SMS disabled; Rem
msg: ”.

Note

The information about SIM charge and expiration date are
not saved in the SIM card, but are managed by the network
operator; the instrument can not get directly the information.
To prevent the discharge of the SIM card, the user has to
configure manually (according with the credit stored on the
SIM card) the maximum number of SMSs that can be sent
(see “Interface configuration” section).

Note

Find here below a complete list of available information (and
coded notations) in the INSTRUMENT> field for all HI142 devices connected to the
HI504903 interface:
• “Temp: ###.#C or F”: temperature reading in Celsius

(“C”) or Fahreneit (“F”) unit, depending on last datalogger
configuration. If the meter is currently logging, then the
displayed temperature value is the last logged sample, oth-
erwise (logger is in delayed start or log ended status) it is
the real time temperature reading during last polling pro-
cedure. If the reading is over-range the indication will be
“>>>>>”, while for under-range value the displayed
indication will be “<<<<<“.

• : current logger status. There are four

operating status for HI142 loggers:

• “Log wait... (

NING>)”: the logger is currently waiting to start the log-
ging procedure; GINNING> field keeps information about date and time
when the HI142 device will start to log the first sample of
the lot.

• “Logging... ()”:

HI142 is currently logging; GING END> field keeps information about date and
time when the HI142 device will record the last sample
of the current lot.

• “Logging... (cyclic memory)”: HI142 is currently logging

in cyclic memory mode; once the memory is full, the log-
ger can continue to log by overwriting the older samples
with the new ones.

• “Log ended”: HI142 is not currently logging; logging

ended or it was interrupted by the user.

• “Low al.: ###.#C or F”: alarm low limit value in Celsius

(“C”) or Fahreneit (“F”) unit, depending on last datalogger
configuration (refer to HI92140 on-line-help for details).
If no low alarm limit was set by the user, then the indication
will be “Low al.: -----C or F”.
