3. Press to choose Set, enter measurement setting menu.

To set the coupling mode: Press F1 to switch Coupling as AC/DC.

To set the sensitivity: Press F2 to switch Sens as Low/Middle/High.

For low amplitude signal, the "Middle" or "High" sensitivity should be used.

For low frequency signal with high amplitude and slower rising edge, low sensitivity is
a better choice.

To set the high frequency restrain on/off:

Press F3 to switch HFR as ON/OFF.
High frequency restrain is used for filtering the high frequency signal in measuring the
low frequency signal, and improve the measure accuracy.
To measure low frequency signal lower than 1kHz, you should put on the high
frequency restrain to filter the high frequency noise disturb.
To measure high frequency signal higher than 1kHz, you should put off the high
frequency restrain.

To set the trig level: Press
value, press
number keys to input the desired value and choose the unit. The range of trig levle is
0～2.5V.

Press F5 to choose Back to previous menu, view the result.
After all the set was done, the counter will measure the signal according to the current set.
If the reading is unsteady, please repeat the above step until it is steady.
