•Data Hold
Press HOLD to freeze the displayed value. Press again to resume measurement.
•Automatic Shutoff
The meter shuts off after 15 minutes of inactivity by default. When shut off, press WAKE or turn the rotary selection switch to reactivate the
multimeter. To deactivate the automatic shutoff function, press the power switch and WAKE simultaneously. Remember to shut off the multimeter
using the power switch after use as the multimeter will still drain batteries when in standby.
•Relative Value Measurement
This function applies for all measurement except for frequency, duty cycle and diode measurements. Press REL∆to determine the relative value.
The next displayed value represents the present measured value minus the recorded relative value. Press again to exit the function.
•Maximum/Minimum Value Measurement
This function applies for all measurement except for frequency and diode measurements. Press MAX/MIN to determine the maximum, the minimum
or both values respectively. Hold MAX/MIN pressed for 2 seconds to exit the function.
•Connecting the Multimeter to a Computer
Connect your DVM2000 to a computer using the included optical USB cable. Hold HOLD pressed for 2 seconds to send the data to the computer.
You will now be able to edit the recorded data on your computer using the appropriate software. Hold HOLD pressed for 2 seconds to stop sending
the data.
