Panel LB-755A is a recorder of the measurement data sent by the attached to it two LAB-EL measurement devices type LB-XXX, each equipped with an interface S300.
The measurement data received is presented on a built-in display and can be registered automatically in a capacious non-volatile internal memory. The recorded data can be viewed directly on a panel display, sent to a computer in order to be documented on the disk files as well as printed directly in a form of reports on an outside printer. A user can determine the upper and bottom values for all of the measured values. Exceeding the measured threshold volume value is signaled by a sound signal and a switch on of a LED diode built-in the panel.
Ultimately the panel will cooperate with all of the LAB-EL devices type LB-XXX, equipped with an interface S300. Available at present version (3.0.0) can cooperate simultaneously with two of the following devices:
Because some of the mentioned above devices perform simultaneously the measurements of few values, the panel’s LB-755A display presents their values alternately. Except from a numerical quantity of a given value and its unit, an information is displayed about a channel to which the device is attached, from which comes the measurement result and a section number attributed to the actually displayed value (i.e. LB-710 has two sections – temperature and humidity and LB-710T one field). Additionally an information can be displayed about the alarm in case when the actually displayed value exceeds set to it alarm thresholds.
The recorder LB-755A is equipped with one or two thermometers LB-710T (measurement of one or two temperatures) or a thermometer LB-711 (measurement of up to eight temperatures) is especially recommended for temperature registry in the trucks. Using intelligent thermometers with digital transmission resulted in elimination of influences (caused by a connection quality) on a measurement result between the recorder (installed in a truck’s cabin) and the thermometers (installed on a semi-trailer). It allows on using the typical outside cables with the terminals installed in a tractor’s driver cabin and on the semi-trailer with measurement correctness guarantee (authenticated by a Calibration Certificate from the Accredited Laboratory LAB-EL) independently from which one of the semi-trailers is to be attached to the tractor.
The panel is equipped with an extensive memory in which the measurement data may be collected. It is possible to register the measurements in the memory: from 30540 points for registry of one temperature ( LB-710T), up to 2545 points for registry of 16 temperatures (2 x LB-711). The number of measurements is configured through selecting the adequate LAB-EL devices cooperating with the panel. A user decides about the crucial parameters for the whole session, when beginning the registry session, in particular:
After starting the session, the changes in those parameters are not possible, this blockage lasts until the end of the session and memory cancel.
The recorded data can be viewed directly on the panel’s display and
can also be sent to a computer in order to visualize and document the
course of registry in the files or print out on an attached small
printer, the data form optionally chosen time interval.
The reports created by the panel are specific documents that visualize history of the stored measurement results. A report can be created from a chosen by a user period of time (choosing an accurate date for the report’s beginning and end) or by choosing for the report the last hours of registry. It is possible to print out two types of reports: simplified and full.
A simplified report includes:
A full report includes apart from all of the information mentioned
above also the following values of the recorded measurements results
(measurement history). In every line of the measurement history a
symbol ! can appear informing that the alarm status was signaled it
that channel. Additionally the following measurement history positions
can be interrupted by the line with the information stating that in
this section the panel’s power supply was switched off and there is no
continuity in the recorded data.
