WXF-ONST8HOBO MX Analog/Temp/RH/Light Data Logger, InTemp CX460 4-Channel Analog Data logger

29123-A1 InTemp CX460 Data Logger Models: • 4- Channel Analog (CX460) Included Items: • Two AAA 1.5 V alkaline batteries (installed) Required Items: • InTemp app • Mobile device with Bluetooth and iOS, iPadOS®, or Android™, The InTemp CX 4-Channel Analog (CX460) data logger measures and transmits data wirelessly to a mobile device using Bluetooth® Low Energy (BLE) technology. The CX460 has four analog inputs and supports a wide variety of external sensors (sold separately), including self- describing temperature, split-core AC current transformer, 4- 20 mA input, and DC voltage input sensors. The self-describing sensors are designed with integrated strain relief for a secure connection to the loggers and are automatically detected by the InTemp® app for easy setup. Using the app, you can configure the loggers, read out and view data, and export the data for further analysis. The loggers can calculate minimum, maximum, average, and standard deviation statistics and can also be configured to trip audible or visual alarms at thresholds you specify. This compact logger also has a built-in LCD screen to display current sensor readings, logging status, battery use, memory consumption, and more. Specifications InTemp® CX 4-Channel Analog CX460 Data Logger User Guide Logger Operating Range -20° to 70°C (-4° to 158°F) Radio Power 1 mW (0 dBm) Transmission Range Approximately 30.5 m (100 ft) line-of-sight Wireless Data Standard Bluetooth Low Energy Logging Interval 1 second to 18 hours Start Modes Start now, on interval, on button push, after elapsed time, or date & time Time Accuracy ±1 minute per month at 25°C (77°F) Battery Type Two AAA 1.5 V alkaline batteries, user replaceable Battery Life 1 year, typical with logging interval of 1 minute and Bluetooth Always On enabled; 2 years, typical with logging interval of 1 minute and Bluetooth Always On disabled; and temperatures between 0° and 50°C (32° and 122°F). Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life. Memory 4 MB (1.9 million measurements, maximum) Full Memory Download Time Approximately 4 to 15 minutes depending on the mobile device; may take longer the further the device is from the logger LCD LCD is visible from 0° to 50°C (32° to 122°F); the LCD may react slowly or go blank in temperatures outside this range Size 11.28 x 5.41 x 2.92 cm (4.44 x 2.13 x 1.15 in.) Weight 123 g (4.34 oz) Environmental Rating IP54 See last page InTemp CX 4-Channel Analog (CX460) Manual U.S. and International Sales: 1-508-743-3309 2 www.onsetcomp.com Logger Components and Operation Self-Describing Sensor Mounting Loop Analog Sensor Port: Use this 2.5 mm jack to connect a self- describing sensor or other analog sensor. The CX460 has four ports. Top Button: Press this button for 3 seconds to start logging (if the logger is configured with the Start On Button Push option). This requires configuring the logger in the app with a logger profile that has Start on Button Push selected for the start mode (see Configure the Logger). You can also press the top button for 1 second to wake up the logger, bring the logger to the top of the list in the app, cycle through each channel on the LCD, and silence a beeping alarm (see Logger Alarms). Bottom Button: You can press this button for 1 second to wake up the logger or silence a beeping alarm. Press both the top and bottom buttons simultaneously for 10 seconds to reset a logger password. Self-Describing Sensor: This is a type of external sensor available for CX460loggers. Turn the sensor plug one-quarter clockwise when inserting it into an analog sensor port to secure it in place. This sensor also features automatic detection by the logger (see Working with External Sensors). Plug: Use this Santoprene® (TPE) plug to fill an empty analog sensor port. Mounting Loops: Use the two mounting loops (only one visible in the diagrams) to mount the logger (see Mounting the Logger). LCD Screen: This logger is equipped with an LCD screen that displays details about the current status. This example shows all symbols illuminated on the LCD screen followed by definitions of each symbol. LCD Screen Plug LCD Symbol Description The logger is waiting to be started or restarted. Press and hold the top button for 3 seconds to start the logger; the logger also displays HOLD during this time. The logger displays HOLD when you press the top button for 3 seconds to start the logger, or while pressing the bottom button for 3 seconds to clear an alarm. The logger displays NEXT when it is logging more than one. Press the top button to cycle through each channel to view sensor measurements. The battery indicator shows the approximate battery power remaining. The logger is set to Stop When Memory Fills. The memory bar indicates the approximate amount of storage space remaining in the logger. When the logger first starts logging data, all five segments are empty. The logger is currently logging. The bell icon indicates a sensor alarm has tripped. Press the top button to view the channel with the alarm icon. This indicates a problem with an external sensor. See Working with External Sensors for more details. This is an example of a sensor reading, with the latest reading displayed above the unit type for that sensor. To switch between US and SI units, change the units in the Settings area of the app (reconfigure the logger to have your unit’s changes take effect). Note: If the sensor value exceeds five digits, the scientific notation E3 is appended to the value on the LCD to signify that the displayed digits are multiplied by 1,000 The logger has been configured to start logging on a particular date/time. The display counts down in days, hours, minutes, and seconds until logging begins. In this example, 5 minutes and 38 seconds remain until logging begins. The configuration settings are being loaded onto the logger from the app. The logg…

HOBO® MX Analog/Temp/RH/Light (MX1104) and MX 4‐Channel Analog (MX1105) Data Logger Manual 23968‐B The HOBO MX Analog/Temp/RH/Light (MX1104) and HOBO MX 4‐Channel Analog (MX1105) data loggers measure and transmit data wirelessly from indoor environments to mobile devices using Bluetooth® Low Energy technology. The MX1104 model has integrated temperature, relative humidity (RH), and light intensity sensors and one analog input while the MX1105 model has four analog inputs. Both models support a wide variety of external sensors (sold separately), including self‐describing temperature, split‐core AC current transformer, 4‐20 mA input, and DC voltage input sensors. The self‐describing sensors are designed with integrated strain relief for a secure connection to the loggers and are automatically detected by the HOBOmobile app for easy setup. Using the app, you can configure the loggers, read out and view data, and export the data for further analysis. The loggers can calculate minimum, maximum, average, and standard deviation statistics and can also be configured to trip audible or visual alarms at thresholds you specify. In addition, both loggers support burst logging in which data is logged at a different interval when sensor readings are above or below certain limits. These compact loggers also have built‐in LCD screens to display current sensor readings, logging status, battery use, memory consumption, and more.
