Installation / Setup
The installation/setup highlights for the Models 750, 751, and 752 dataloggers include the following:
– Install the AK-75X software on your PC and connect the IR interface to the serial port (COM1 or COM2).
– Ensure the IR interface of the datalogger is facing the IR interface connected to the PC for scanning.
– Set up the time and date by transferring the PC’s date and time to the datalogger.
– Configure the datalogger by naming it, selecting measurements, sampling rate, and start/end of measurements.
– Ensure the IR window is clean and do not exceed specified voltage and temperature limits.
– Use the software to send the setup to the datalogger and start measurements.
– External connections should not exceed 20 volts, and all inputs have common ground connections.
– Replace the lithium battery as needed, noting polarity and using the correct replacement battery. Model 750 requires seal replacement for waterproofing.
Operation
To operate the datalogger models 750, 751, and 752, follow these steps:
1. Install the AK-75X software on your PC and connect the IR interface to the computer’s serial port (COM1 or COM2). Verify the correct serial port and speed (19200 bps) in the software’s [Option] menu.
2. Use the [Scan] function to search for the datalogger by positioning its IR interface facing the PC’s IR interface. Ensure not to scan two dataloggers with the same address simultaneously.
3. Set up the time and date by transferring the PC’s date and time to the datalogger through the [Option] + [Date & Time] menu.
4. Configure the datalogger by accessing the [Setup] icon or [Datalogger] + [Datalogger Setup] menu. Assign a name, select measurements, sampling rate, start and end of measurements, and set alarms if needed. Send the setup to the datalogger by clicking on SEND SETUP.
5. Start measurements by clicking the [Start] icon. The green LED will flash every 3 seconds to indicate the start command has been processed.
6. Stop measurements by clicking the [Stop] icon. The red LED will flash once, and the green LED will stop flashing.
7. To read stored measurements, click on the [read] icon to transfer data to the computer, where it will be displayed on a chart.
8. Process the data using the software’s features to zoom, adjust scales, add comments, and export data to text or Excel files. Save your data as it will only read from files with a T15 extension.

Safety & Warnings
Do not exceed 30V for input voltage. Alarm output should not exceed 20V. Do not exceed the operating temperature range of -40°F to 185°F (-40°C to +85°C). The IR link operating range is 32°F to 185°F (0°C to 85°C). Ensure the IR window is clean. Using the AK-75X software in Instantaneous Measurement Mode will significantly reduce battery life. Do not scan two dataloggers programmed at the same address simultaneously. Fast sampling rates will reduce battery life. Alarm usage will reduce battery life due to flashing LEDs. Maximum voltage for voltage input must not exceed 25 Volts. When replacing the battery in Model 750, replace the seal to maintain IP68 protection if necessary.
