reading with a normally open contact (high to low transition of the trigger signal) or a normally closed
contact (low to high transition).
Before the parameters of External Trigger Mode can be configured, it must be enabled. To do so, enter
the main menu, select External Trigger, scroll to one of the four available options and press ENTER.
The options are as follows:
Option Description
Momentary High Low The display will freeze the captured reading until ZERO is pressed. Applies
to a high to low transition of the trigger signal.
Momentary Low High The display will freeze the captured reading until ZERO is pressed. Applies
to a low to high transition of the trigger signal.
Maintained High The display will show the captured reading only for as long as a high signal
is maintained.
Maintained Low The display will show the captured reading only for as long as a low signal
is maintained.
After the selection has been made and the menu has been exited, press MODE until ET is displayed.
External Trigger mode is now armed. Refer to the pin diagram in the Communications section for
connection information.
To exit External Trigger mode, press MODE and select the desired measuring mode.
Note: As long as external trigger has been enabled, it is still active even if the indicator is in Real Time
mode. After the display freezes, any programmed set points will be active. However, if the indicator is in
External Trigger mode, any programmed set points will be inactive.
6 DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select Filters from the menu. The display will appear as follows:
