3. To Set the Trig Level
The trig level (-3V～+3V) is divided into 1000 (00.0~99.9) shares, each “0.1” is 6
mV, it means the adjustment interval is 6 mV. For example, the input is “62.0”,
then the trig level is: -3V + (62.0 / 0.1) × 6 mV=0.72V.
(1) Press Utility Count Setup TrigLev to set the trig level.
The trig level display on the screen is the default value when power on or the
value set at the last time. If the current value is effective, it could be use
immediately.
(2) Input the required trig level.
Use the knob to change the value as shown in the following figure, the counter
will immediately adjust the trig level, and trigger according to the specified value.

To set the trig level
NOTE: In DC coupling mode, users need to adjust the trig level manually.
