MI 3309 BT DeltaGT General description 1 General description The multifunctional portable appliance tester DeltaGT is intended to measurements for testing the electrical safety of portable electrical equipment.
MI 3309 BT DeltaGT General description 1.1 Warnings In order to reach a high level of operator safety while carrying out various measurements using the instrument, as well as to keep the test equipment undamaged, it is necessary to consider the following general warnings: Warning on the instrument means »Read the Instruction manual with special care to safety operation«.
MI 3309 BT DeltaGT General description 1.2 Battery and charging The instrument uses six AA size rechargeable NiCd or NiMH battery cells. Alkaline battery cells are not allowed. Battery condition is always displayed in the upper right corner of the display. If the battery power becomes too weak, the instrument indicates this as shown in Figure 1.1. This indication appears for a few seconds and then the instrument turns itself off. Figure 1.
MI 3309 BT DeltaGT General description 1.3 New battery cells or cells unused for a longer period Unpredictable chemical processes can occur during the charging of new battery cells or cells that have been left unused for a longer period (more than 3 months). NiMH and NiCd cells can be subjected to these chemical effects (sometimes called the memory effect). As a result the instrument operation time can be significantly reduced during the initial charging/discharging cycles of the batteries.

Print label An appliance label with barcode will be printed. Print results All the data stored at the specified location will be printed. That includes Appliance ID, Appliance NAME, Test date and time, Overall and individual measurement result (Pass or Fail), individual measurement values, limits and other settings.
MI 3309 BT DeltaGT Communication 8 Communication There are three communication interfaces for communication with PC and other external devices: USB, RS232 and Bluetooth. See chapter 4.8.3 Communication for more information. 8.1 USB communication How to establish an USB link: COM PORT: USB should be selected in Communication menu. Connect the PC USB port to the instrument USB connector using the USB interface cable. Switch on the PC and the instrument. Run the PATLink PRO program.
MI 3309 BT DeltaGT Communication 8.3 Bluetooth communication The internal Bluetooth module enables easy communication via Bluetooth with PC and Android devices. How to configure a Bluetooth link between instrument and PC: Switch On the instrument. On PC configure a Standard Serial Port to enable communication over Bluetooth link between instrument and PC. Usually no code for pairing the devices is needed. Run the PATlinkPRO program. Set communication port and baud rate speed.
MI 3309 BT DeltaGT Communication If printing from Android device be sure that Zebra printer is selected in the Metrel Android application as the Bluetooth printer. The configuration tool is available in the Metrel's Android application. The instrument and printer are ready to communicate. Notes: The name of a correctly configured Bluetooth device must consist of the instrument type plus serial number, eg. MI 3309 BT-12240429D.
MI 3309 BT DeltaGT Maintenance 9 Maintenance 9.1 Periodic calibration It is essential that all measuring instruments are regularly calibrated in order for the technical specification listed in this manual to be guaranteed. We recommend an annual calibration. The calibration has to be done by an authorized technical person only. 9.

MI 3309 BT DeltaGT Appendix A – Barcode and QR code formats Appendix A – Barcode and QR code formats Barcode formats The instrument DeltaGT supports two barcode formats (single and double). Autotest code and appliance ID Autotest codes are represented as a three digits code. These autotest codes can also be represented by the barcode. Using the barcode scanner, the instruments can accept autotest code from barcode label. A0 1 Autotest code Also appliance ID can be read from barcode label.
