Automatic range adjustment can turn the range up to 120% of the current range and down to less than 10% of the current range. Step 5: Auto Zero: Auto Zero provides the most accurate measurement, but requires additional time to perform the reset-to-zero measurement.
  • Page 31 The AC voltage This section describes how to configure AC voltage measurement from the front panel. Select the default delay to give the correct first reading for most measurements. For the most accurate measurements, the input that prevents the RC time constant must be stabilized to 1/50 of the AC signal level.
  • Page 32 Step 2: Press [ACV] on the front panel. Step 3: Press Range to choose a range for measurement. Auto (auto range adjustment) selects range for measurement based on input. Compared with manually selected range, auto range adjustment is more convenient but can lead to slower measurement.

  • Page 95 Capacitance offset calibration (optional) In general, this calibration is not required. This procedure usually compensates for residual capacitance offsets that are less than a few pF. In normal use, any residual offset is overwritten by the null function (the null function also corrects the cable capacitance), and it is also required to use the null function to implement the capacitance specification of the multimeter.

    Chapter 5 Remote Control USB Communication Connect the Type-A end of the USB cable to the computer, and connect the Type-B end to the USB port on the back of the DMM. A new device will be displayed in the computer device manager.
  • Page 97 After installation, you can see the running IO software in the lower right corner of the screen. Double-click to open the IO software, you can see the connected device information displayed under My Instrument-USB. Click "Interactive IO", send an instruction arbitrarily, and the computer and the oscilloscope will communicate.
  • Page 98 Click “Next” to finish the software install.
  • Page 99 Double-click the software shortcut to open the host computer software, At this point, the host computer has been connected.

    LAN Communication The procedure for LAN communication is as follows: Connect one end of the network cable to the computer and the other end to the back-end LAN port of the multimeter. To set the HDM3000, click Shift+Display to access the I/O Config page in the Utility.
  • Page 101 Manually change the IP address of the computer to the same network segment as the DMM. Open IO, select “LAN instrument” in “Manual Configuration”, and enter the IP Addr of HDM3000 in “Hostname or IP Address” of “Set LAN Address”. “Set Protocol”...
  • Page 102 Click Accept, and the new device is automatically generated in the Instruments column. If IP Mode is set to DHCP in LAN Settings in Step 2, You do not need to manually Set IP Addr and Gateway. Click Apply. The router connected to the DMM automatically assigns IP addresses to the DMM.
  • Page 103 address successfully" is displayed, if failed, the display is “Map IP address failed!”. If the DHCP assignment failed, the original IP address of the DMM is not changed. After the DHCP IP address is successfully assigned, the communication between DMM and PC is as the IP Mode Static.
