TRIGGER CONTROL

5. ↓↑ Toggles the trigger slope (rising or falling). The current trigger

slope is indicated on the top right of the display.

↑= trigger on rising edge

↓= trigger on falling edge

6. TRIG There are three Trigger Modes: NORMAL, AUTO, and SINGLE

SHOT. Pressing 6 cycles through the three modes.

In NORMAL mode (the default mode), the Tester waits for the

trigger to occur before the waveform is displayed. Normal mode is

indicated by a "n" in the upper right corner of the display.

In AUTO mode, if a trigger does not occur for 250 ms, a trigger is

forced to occur. This allows signals to be found more easily since

the display shows the waveform even when a trigger does not

occur. Auto mode is indicated by an "a" in the upper right corner of

the display.

In SINGLE SHOT mode, the trigger is only activated when the

signal crosses the trigger level, or the E key is pressed.

While waiting for the trigger the single shot indicator shows an

upper case "S". When a trigger occurs, the indicator changes to a

lower case "s". The display remains frozen until the E key

is pressed, or a new trigger mode is chosen.

7. HOLD The HOLD mode freezes the current display so that the waveform

can be analyzed. The display is frozen until the 7 key is pressed

again, the trigger mode is changed, or the display is adjusted (time

scale or scale changed). When the hold mode is active, the right

Red LED is turned on.
