Page 11: Recommendations For Mounting
Recommendations for mounting Do not mount Multilogger near sources of interference (Multilogger must not be mounted directly to power switchboard nor to its nearness. Also do not mount data logger near power contactors, motors, frequency converters and other sources of strong interference). ... - Page 12 Do not use cables longer than 30 m generally; for RTD sensors is recommended max. 15 m; cables must be installed only in interior areas. Do not interconnect the inputs with other measuring systems. Use shielded cables for the voltage and current inputs - connect the shielding to the Multilogger but not to the end devices if these do not have a special terminal for it.
- Page 13 Do not use common leads for several inputs. It is recommended to earth larger systems with Multilogger at one point - the GND terminal of the alarm output can be used for this purpose. This grounding will work correctly if the system would not be grounded currently at another point too.

Page 33: Device Setup Using Software
Complete configuration of the device can be done using the Atal Vision software. Some parameters can be changed from the device keyboard or from its web pages. When editing the Multilogger... - Page 34 General - Preferences ____________________________ Here you can select language localization Language on the device terminal, Default temperature unit °C/°F and, for some models, Atmospheric pressure unit. If your model does not measure atmospheric pressure but it is necessary to know it (for calculated humidity values and CO concentration), you need to specify Ambient average pressure.
- Page 35 General - Advanced - Device start ___________________ Here you can disable the “Off key” of the device. General - Advanced - LCD Display __________________ These settings are used for optimizing the backlight of the display in relation to your application. As a default, the Multilogger is set in a way that the backlight (LCD backlight activity) is activated only for several seconds upon the last key pressing.
- Page 36 Recording can be continuous or, alternatively, records can be taken only if any measured quantity is in the alarm state (the system alarms does not trigger recording). Moreover, Multilogger with binary input No. 3 also offer the option to control the recording by the status of this binary input.
- Page 37 It can be optionally applied to acoustic signalization, the ALARM OUT output or both. It can be performed from the keyboard, from the web or from the software Atal Vision. To protect access to these functions, you can use the PIN2 code, which the operation personnel must enter.
- Page 38 Alarm events - Memory occupation __________________ If you need to indicate exceeding of your specified limit of the data memory occupation, use the setup in this section. The signalization can be selected as optical (red LED diode), acoustic, or by the means of the ALARM OUT output activation or sending email to selected recipients.
- Page 39 Ethernet - General _______________________________ Here, you can make the basic connection setup of the Ethernet interface. To obtain some information, you will need to contact your computer network administrator. First of all, you have to find out if you are going to use a fixed IP address or if it will be assigned by the DHCP server in your network.
- Page 40 You can use shortened emails (Short email) especially for forwarding them as SMS messages to mobile phones. You can also insert your own comments to the emails: if the alarm appears (Alarm note), if the alarm expires (Clear alarm note), in the case of system alarm (System alarm note) and in the case of exceeding the memory occupation limit (Memory overflow note).
- Page 41 Inputs _________________________________________ Here you can specify the quantities that you will measure on every one inputs, their recording and alarm states. You can see a simple list of all inputs and measured quantities on the screen. First of all, specify the probe or signal types connected to each input (Settings button).
- Page 42 Next, select if the alarm occurs upon exceeding or dropping under the given limit value (value is greater than / value is lower than) and enter this limit. For binary inputs only define the state of the input. Next, you need to specify the alarm delay (for the duration of), which is used for eliminating short-term exceeding of the limit value.

Page 43: Applications Notes
Applications notes Recommended settings for the portable application______ In this application, the Multilogger is powered from batteries and a fast response time and an easy battery recharge after the measurement are required. Recorded data are downloaded after measurement. We recommend to use the Multilogger with NiMH accumulators; specify the following device configuration: ... - Page 44 Set the acoustic alarm signalization as needed. If you want to operate the Multilogger “remotely”, disable “Off key” on its keyboard (Atal Vision software, option General - Advanced - Device start). You will thus prevent unauthorized or unwanted device turn-off by unqualified personnel.
- Page 45 Recommended settings for a long time battery powered application ______________________________________ In this application, the Multilogger is powered only from batteries and a fast response to changing measured quantities is not required, however, it is required that the device runs from the batteries as long as possible.
- Page 46 If the Multilogger is not equipped with an internal pressure sensor, you have to enter this value using the SW in the device configuration, item General - Preferences. You can enter either the current pressure value at the given location (without conversion to the sea level) or the current altitude.
- Page 47 Multilogger reports this error, the batteries are empty. You can check the battery status in the System information menu or in the software Atal Vision on the Device home page. If the battery voltage drops under 3.45 V, the Multilogger reports a self-test error. A drop of the power supply voltage is also indicated by the given symbol the device status line.
- Page 48 A similarly for sensors with a voltage or current output - unwanted couplings can cause incorrect measurements. If the Multilogger reports an error state, you can find more information in Appendix 1 - Selected error messages. Another group of problems are random spikes of the measured values.

Page 49: Operation And Maintenance Recommendations
Operation and maintenance recommendations Device operation in various applications _______________ Before application it is necessary to consider if Multilogger is suitable for required purpose, adjust optimal configuration and create instructions for its periodical metrological and functional inspections. Since the Multilogger can be powered from the power mains, it is necessary (depending on the character of the application) to secure the appropriate electric revision of its installation and its regular inspections. - Page 50 Recommendations for metrological verification _________ Metrological verification is performed in accordance with application requirements specified by the user. In some cases, calibrations must be performed by the accredited laboratory. The manufacturer recommends to perform these verifications once a year. Note: accuracy of Multilogger input means accuracy of input itself without probes.

Page 54: Alarm Out Output
Fast charging mode current: approximately 350 mA ________________________________________________________________________________________________ Fast charging has to be activated by the Multilogger user. During the fast charging, the Multilogger does not take any measurements nor recording and does not communicate with the computer. Fast charging time: Up to 6 hours Fast charging restriction: Allowed in ambient temperature from 0 °C to 40 °C. -
Page 55: Communication Interfaces
Communication interfaces The Multilogger is equipped with USB, Ethernet and RS232C interfaces with automatic detection of a connected cable. Only one of these interfaces can be used for communication at one time. The USB interface has the highest priority (if the Multilogger is connected via its USB port, the other two interfaces are automatically disabled) while the Ethernet interface has the lowest priority (for its proper function, it is necessary that neither the RS232C nor the USB interfaces are connected). -
