3. The Keys
Make sure to connect your DVM13MFC2U to an AC 220V/110V (± 10%) mains socket. Maximum consumption is 5W. Switch on your device
20 minutes before measuring. This preheats the unit and the crystal oscillator to ensure accurate readings and stability.
FUNCTION key (3 steps)
Step 1: 50MHz ~ 2.4GHz range, input from channel B, measurement unit indication in MHz/ms.
Step 2: 2MHz ~ 50MHz range, input from channel A, measurement unit indication in MHz/ms.
Step 3: 0.01Hz ~ 2MHz range, input from channel A, measurement unit indication in KHz/s.
PERIOD key
Press this key to enter the period measurement mode.
CONFIRM key
Press this key, the instrument will start working according the preset mode.
AC/DC COUPLING key
Position this button in the down position for DC measurements. Position this button in the up position for AC measurements.
RESET key
Press this key to reset your DVM13MFC2U.
ATT key
Position this button in the down position for a measurement attenuated by 20dB. Position this button in the up position for a non-
attenuated measurement.
4. Operation
Make sure to match the voltage from the local mains with the voltage on your DVM13MFC2U.
Check the 220V/110V switch at the back of the device.
Connect the power cord to a power outlet (AC 220V/110V, 50Hz or 60Hz) and switch on your DVM13MFC2U. Allow the unit to warm up for
20 minutes.
