• Hysteresis (hysteresis width)
Set the hysteresis based on the fluctuations in the measured values around the trigger level.
Hysteresis is applied from the start of the sampling period and prevents timing input chattering.
• Zero reset input is disabled during sampling or while [-----] is displayed in the main display.
• The timing input signal is ignored if the self-trigger level is set to [UP] or [DOWN]. However,
sampling is not affected.
• When a delay time is set, the timing when the measured value falls below or exceeds the self-
trigger level is not synchronous with the end of the sampling period. Sampling ends after the
specified sampling period has elapsed.
Selecting the trigger direction
1.
Use the LEFT and RIGHT keys to display [H-
TRD] on the main display.
H-TRD is not displayed if the hold condition is set to
[OFF].
2.
Press the UP or DOWN key.
The sub-display flashes.
3.
Use the UP or DOWN key to select the
desired trigger type.
[There are three trigger types: [UP], [DOWN] and
[WINDW].
4.
Press the ENT key to confirm the setting.
This registers the selected trigger type.
Setting the self-trigger level (example: when [WINDW] is selected as the trigger direction)
There are two self-trigger levels, [H-LVH] and [H-LVL]. The self-trigger level to be specified differs
according to the trigger direction.
• When trigger direction = UP, specify [H-LVL].
• When trigger direction = DOWN, specify [H-LVH].
• When trigger direction = WINDOW, specify both [H-LVH] and [H-LVL].
