For low frequency large signals or signals with slow rising edges, low
sensitivity is selected and the measurement results are more accurate.

Press the HF Suppression softkey to toggle ON or OFF high frequency
rejection.
High-frequency rejection can be used to filter high-frequency components
when measuring low-frequency signals, improving measurement accuracy.
When measuring low frequency signals with a frequency less than 1 kHz,
turn on high frequency rejection to filter out high frequency noise
interference; turn off high frequency rejection when measuring high
frequency signals with frequencies greater than 1 kHz.
 Press the Trigger Level softkey. Turn the knob to change the current cursor
position value, press the arrow keys to move the cursor left or right; or use
the numeric keypad to enter a value and then select the desired unit from
the right menu. The trigger level ranges from -2.5 V to 2.5 V.
After the setting is completed, the frequency meter will measure the signal
to be tested at the current setting. If the reading is unstable, repeat the
above adjustment until the display is stable.
