The Rear Panel

1. Connect the terminals and the current input fuse.
   The multimeter uses two types of fuses to provide input protection for small and large current ranges. The internal fuse provides the maximum protection limit of 10.5A for the input of large current range. The fuse will be blown when the input current exceeds 10.5A. The rear panel current input fuse provides the maximum protection limit of 3.1A for small current range input, and the fuse will be blown when the input current exceeds 3.1A. The multimeter is equipped with a high current input fuse when leaving the factory. If you need to replace the small current fuse, please do it in the following way:

   • Turn off the power of the multimeter and unplug the power cord.
   • Use the straight screwdriver to push in slightly and rotate along the direction shown in the picture to pull out the fuse holder.
   • Replace specified fuses.
   • Put the fuse holder into the card slot.
     Note: the large current input fuse is located inside the instrument and is not allowed to be replaced by the user. If needing replacement, please contact Qingdao Hantek Electronic Co., Ltd.

2. The fan

3. The GPIB interface (non-standard)
   This interface can be configured using the Keysight IO Libraries Connection Expert utility.

4. Power jack
   This multimeter can input two specifications of AC power supply. Connect alternating current to the multimeter through the socket using the power cord provided in the attachment.
   Note: Please select the correct voltage range (using voltage selector) before connecting AC.

5. VM Comp
   You can use the VMC OUT soft key to set the edge slope of the VM Comp (voltmeter complete) output on the rear panel of the instrument. This connector emits a signal whenever completing a measurement, allowing you to send signals to other devices in the measurement system.

6. External trigger input
   You can trigger a multimeter by adding a trigger pulse to the [Ext Trig] connector. At this point, you need to select an external trigger source.

7. LAN interface
   Through this interface, the multimeter is connected to the network for remote control.

8. The RS232 interface
   Through this interface, the computer is connected to the multimeter. You can control the multimeter remotely using the SCPI command or PC software.

9. USB Device interface
   Through this interface, the computer is connected to the multimeter. You can control the multimeter remotely using the SCPI command or PC software.

10. The power fuse
    The multimeter leaves the factory with a power fuse installed. If needing to replace the fuse, please do it in the following way:

    • Turn off the power of the multimeter and unplug the power cord.
    • Use the screwdriver to press the tongue, and then pull out the fuse seat.
    • Select the correct voltage range at the voltage selector.
    • Replace the specified specification of the fuse.
    • Put the fuse holder into the card slot.

11. Voltage selector
    Select the correct voltage range according to the AC specification you are using. Two AC input voltage ranges are available: 110 V and 220 V.

First Use of The Multimeter

When using the multimeter for the first time, refer to the steps below to start the multimeter.

1. Connect the AC power supply.

   • Adjust the power supply voltage selector on the rear panel according to your power supply voltage.
   • Connect the multimeter to the AC power supply using the power cord.

2. Start the multimeter.

   • Press the power button on the front panel to start the instrument.

3. Start-up process
   Normal startup: Display the user interface.

4. If the instrument does not start normally, please follow the following steps to check.

   • If the instrument is still not started after checking without error, please check whether the power fuse has been blown. If necessary, please replace the fuse.
   • If the instrument is still not started after the above check, please contact Qingdao Hantek Electronic Co., Ltd.

Measuring Connection

This multimeter provides a variety of measuring functions. After selecting the required measuring function, connect the measured signal (device) to the multimeter as shown in the following figure. In the process of measurement, do not switch the measuring function at will, otherwise it may damage the multimeter. For example, do not use the measuring lead to measure AC voltage when it is connected to the current terminals.

Note: To avoid damaging the multimeter, be sure to follow the instructions below for DC/AC current measurements.

1. When measuring the current, make sure to select the correct current input terminal according to the expected current size before switching on the multimeter power.
